# GPS Module Wiring Guide
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This guide shows how to connect a GPS module (e.g., MakerFocus GT-U7, NEO-6M) to the ESP32 boards supported by this firmware. The GPS provides NMEA sentences for position/time and an optional PPS (pulse-per-second) signal for precise timing.
|
||||||
|
|
||||||
|
## Supported GPS Modules
|
||||||
|
|
||||||
|
- **MakerFocus GT-U7** (recommended) — 3.3V compatible, NMEA output, PPS, 9600 baud default
|
||||||
|
- **NEO-6M** — Same pinout and NMEA format
|
||||||
|
|
||||||
|
## Connections Required
|
||||||
|
|
||||||
|
| GPS Pin | ESP32 Side | Function |
|
||||||
|
|---------|------------|----------|
|
||||||
|
| VCC | 3.3V | Power (3.3V only) |
|
||||||
|
| GND | GND | Ground |
|
||||||
|
| TXD | ESP32 RX | NMEA data from GPS → ESP32 |
|
||||||
|
| RXD | ESP32 TX | Optional: config/commands to GPS |
|
||||||
|
| PPS | GPIO input | Pulse-per-second (optional but recommended) |
|
||||||
|
|
||||||
|
**Note:** TX and RX are crossed: GPS TXD → ESP32 RX, GPS RXD → ESP32 TX.
|
||||||
|
|
||||||
|
**Power with SD card:** If you also use the SparkFun microSD breakout, **J1 Pin 1 (3.3V)** and **J1 Pin 15 (GND)** must use **Y-cables**: one branch to the GPS, one to the SD breakout, so both devices are powered from the same 3.3V and GND. See [SD_CARD_WIRING.md](SD_CARD_WIRING.md) for the combined pin diagram.

|
||||||
|
|
||||||
|
### Wiring Table
|
||||||
|
|
||||||
|
| GPS Module Pin | ESP32-C5 GPIO | Header Location | Function |
|
||||||
|
|----------------|---------------|-----------------|----------|
|

## ESP32 (Original / Standard)
|
||||||
|
|
||||||
|
| GPS Module Pin | ESP32 GPIO | Function |
|
||||||
|
|----------------|------------|----------|
|
||||||
|
| VCC | 3V3 | Power |
|
||||||
|
| GND | GND | Ground |
|
||||||
|
| TXD | GPIO16 (RX) | GPS → ESP32 |
|
||||||
|
| RXD | GPIO17 (TX) | ESP32 → GPS (optional) |
|
||||||
|
| PPS | GPIO4 | Pulse per second |
|
||||||
|
|
||||||
|
### Quick Wiring
|
||||||
|
|
||||||
|
```
|
||||||
|
GT-U7 VCC → 3V3
|
||||||
|
GT-U7 GND → GND
|
||||||
|
GT-U7 TXD → GPIO16 (RX)
|
||||||
|
GT-U7 RXD → GPIO17 (TX)
|
||||||
|
GT-U7 PPS → GPIO4
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## PPS Polarity
|
||||||
|
|
||||||
|
The firmware supports both **rising-edge** and **falling-edge** (active-low) PPS. Many u-blox GT-U7/NEO-6M modules use **active-low** PPS (line pulls low for ~100 ms at each second). The default is `GPS_PPS_ACTIVE_LOW=1` in `board_config.h`. If PPS Lock shows NO despite correct wiring, try flipping this (set to 0 for rising-edge).
|
||||||
|
|
||||||
|
## Important Notes
|
||||||
|
|
||||||
|
⚠️ **Warnings:**
|
||||||
|
- **Use 3.3V only** — Do not connect GPS VCC to 5V; many modules are 3.3V logic.
|
||||||
|
- **TX ↔ RX crossover** — GPS TXD connects to ESP32 RX; GPS RXD connects to ESP32 TX.
|
||||||
|
- Avoid strapping pins (e.g., GPIO2, GPIO3 on ESP32-C5) for general I/O.
|
||||||
|
|
||||||
|
## Testing
|
||||||
|
|
||||||
|
After wiring, use the `gps` console command to check NMEA output and fix status. Example:
|
||||||
|
|
||||||
|
```
|
||||||
|
gps status
|
||||||
|
gps nmea
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### NMEA Valid: NO
|
||||||
|
|
||||||
|
- **TX/RX swapped** — GPS TXD must go to ESP32 RX (GPIO23 on C5). If you swapped them, NMEA won't parse.
|
||||||
|
- **Wrong pins** — Double-check GPIO numbers. Older guides (e.g. `esp32-c5-gps-sync-guide.html`) use GPIO4/5 for UART; the firmware expects GPIO23/24.
|
||||||
|
- **No satellite fix** — Move the antenna near a window or outdoors. Cold start can take 1–2 minutes.
|
||||||
|
- **Power** — Ensure VCC is 3.3V. Some modules draw more current during acquisition.
|
||||||
|
|
||||||
|
### PPS Locked: NO (but NMEA Valid: YES)
|
||||||
|
|
||||||
|
- **Verify signal** — Run `gps pps-test` (or `gps pps-test -d 5`) to poll the PPS GPIO. If no edges are detected, the signal isn't reaching the ESP32.
|
||||||
|
- **Wrong PPS pin** — The firmware expects PPS on GPIO1 (J1 Pin 6). GPIO25 (Pin 13) is a strapping pin and can interfere; use Pin 6 instead.
|
||||||
|
- **PPS polarity** — Many u-blox modules use active-low PPS. The default `GPS_PPS_ACTIVE_LOW=1` in `board_config.h` triggers on falling edge. If it still fails, try setting `GPS_PPS_ACTIVE_LOW=0` (rising-edge).
|
||||||
|
- **PPS not enabled** — Some modules need UBX configuration to output PPS. GT-U7 usually outputs it by default once a fix is acquired.
|
||||||
|
- **Loose connection** — PPS is a 1 Hz signal; a bad connection will cause missed edges.
|
||||||
|
|
||||||
|
### No Time / No Fix
|
||||||
|
|
||||||
|
- **Antenna** — Active antennas need power; ensure the module’s antenna connector matches. Outdoor or window placement helps.
|
||||||
|
- **Startup delay** — Allow 1–2 minutes for cold start. Check `gps nmea` for $GPGGA with "A" (valid) vs "V" (invalid).
|
||||||
|
|
||||||
|
### Documentation Mismatch
|
||||||
|
|
||||||
|
If you followed `doc/esp32-c5-gps-sync-guide.html`, note its pinout differs from the current firmware:
|
||||||
|
|
||||||
|
| Signal | Old guide | Current firmware |

|
||||||
|
| RX (GPS TXD) | GPIO4, J3 Pin 8 | GPIO23, J3 Pin 5 |
|
||||||
|
| TX (GPS RXD) | GPIO5, J3 Pin 9 | GPIO24, J3 Pin 4 |
|
||||||
|
| PPS | GPIO1, J1 Pin 6 | GPIO1, J1 Pin 6 ✓ (same) |
|
||||||
|
|
||||||
|
Use the pinout in this document for compatibility with the firmware.
|
||||||
|
|
||||||
|
## Configuration Source
|
||||||
|
|
||||||
|
Pin assignments are defined in `main/board_config.h`. To change pins for a custom board, edit the appropriate `#elif defined (CONFIG_IDF_TARGET_...)` block.

# SparkFun microSD Transflash Breakout - ESP32-C5 Wiring Guide
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
This guide shows how to connect the SparkFun microSD Transflash Breakout board to the ESP32-C5 DevKit. **ESP32-C5 does not support SDMMC/SDIO host**, so the firmware uses **SPI mode** for SD card access.
|
||||||
|
|
||||||
|
**If you also have a GPS module (e.g. GT-U7):** J1 Pin 1 (3.3V) and Pin 15 (GND) must each use a **Y-cable** (or splice) so one leg goes to the SD breakout and one to the GPS — both devices share the same 3.3V and GND from the ESP32-C5.
|
||||||
|
|
||||||
|
## Required Connections (SPI mode)
|
||||||
|
|
||||||
|
- VCC (3.3V)
|
||||||
|
- GND (Ground)
|
||||||
|
- CLK (SPI SCLK)
|
||||||
|
- DI (SPI MOSI - Data In to card)
|
||||||
|
- DO (SPI MISO - Data Out from card)
|
||||||
|
- CS (Chip Select)
|
||||||
|
- CD (Card Detect, optional)
|
||||||
|
|
||||||
|
## Wiring Table (SPI Mode)
|
||||||
|
|
||||||
|
| SparkFun Label | ESP32-C5 Pin | Header Location | GPIO Number | Function |
|
||||||
|
|----------------|--------------|-----------------|-------------|----------|
|
||||||
|
| **VCC** | Pin 1 | J1 (Left Side) | 3V3 | Power |
|
||||||
|
| **GND** | Pin 15 | J1 (Left Side) | GND | Ground |
|
||||||
|
| **SCK** | Pin 10 | J1 (Left Side) | GPIO9 | SPI_CLK |
|
||||||
|
| **DI** | Pin 11 | J1 (Left Side) | GPIO10 | SPI_MOSI |
|
||||||
|
| **DO** | Pin 9 | J1 (Left Side) | GPIO8 | SPI_MISO |
|
||||||
|
| **CS** | Pin 8 | J1 (Left Side) | GPIO7 | SPI_CS |
|
||||||
|
| **CD** | Pin 12 | J1 (Left Side) | GPIO26 | Card Detect (Input Pull-up) |
|
||||||
|
|
||||||
|
Note: If your SparkFun breakout does not expose CS, some breakouts tie CS to GND (always selected). The firmware expects CS on GPIO7.

## Combined Pin Diagram (SD Card + GPS)
|
||||||
|
|
||||||
|
When using **both** the SparkFun microSD breakout and a GPS module (e.g. GT-U7 / NEO-6M), power and ground are shared:
|
||||||
|
|
||||||
|
- **J1 Pin 1 (3.3V)** and **J1 Pin 15 (GND)** each need a **Y-cable** (or one 3.3V and one GND split): one branch to the SD breakout, one branch to the GPS. Do **not** rely on a single wire to the first device and then daisy‑chain to the second; use a proper Y (or star) so both get a direct connection to 3.3V and GND.

||||||
|
|
||||||
|

```
|
||||||
|
|
||||||
|
**Summary:** Use Y-cables (or equivalent) on **3.3V (Pin 1)** and **GND (Pin 15)** so the SD card and GPS each have their own lead from the ESP32-C5. Same 3.3V and GND rail, two physical wires per net.
|
||||||
|
|
||||||
|
## Quick Wiring Reference
|
||||||
|
|
||||||
|
```
|
||||||
|
SparkFun microSD Breakout → ESP32-C5 DevKit
|
||||||
|
|
||||||
|
1. VCC → J1 Pin 1 (3V3) [Left side, top; use Y-cable if also powering GPS]
|
||||||
|
2. GND → J1 Pin 15 (GND) [Left side, bottom; use Y-cable if also powering GPS]
|
||||||
|
3. SCK → J1 Pin 10 (GPIO9) SPI_CLK
|
||||||
|
4. DI → J1 Pin 11 (GPIO10) SPI_MOSI
|
||||||
|
5. DO → J1 Pin 9 (GPIO8) SPI_MISO
|
||||||
|
6. CS → J1 Pin 8 (GPIO7) SPI_CS
|
||||||
|
7. CD → J1 Pin 12 (GPIO26) Card Detect (optional)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Card Detect (CD) Logic
|
||||||
|
|
||||||
|
- **LOW (0V):** Card is **Inserted** (default: `CONFIG_SD_CD_ACTIVE_LOW=y`)
|
||||||
|
- **HIGH (3.3V):** Card is **Removed** (pin floats high with pull-up)
|
||||||
|
|
||||||
|
If your breakout uses inverted logic (HIGH = inserted), run `idf.py menuconfig` → **ESP32 iperf Configuration** → **SD Card** → uncheck **Card Detect: LOW = inserted**.
|
||||||
|
|
||||||
|
**Breakout doesn’t support CD:** Some SparkFun-style breakouts have a CD pad or through-hole that is **not** connected to the slot’s card-detect switch (the slot may not have a CD pin). If wiring is correct but status always shows REMOVED (or CD never changes), disable CD: `idf.py menuconfig` → **ESP32 iperf Configuration** → **SD Card** → set **Card Detect GPIO** to **-1**. The card will still mount and work; only insert/remove detection is disabled.
|
||||||
|
|
||||||
|
## Pin Locations on ESP32-C5 DevKit
|
||||||
|
|
||||||
|
### J1 (LEFT SIDE - Top to Bottom):
|
||||||
|
```
|
||||||
|
Pin 1: 3V3 ← VCC
|
||||||
|
Pin 2: RST (Reset - do not connect)
|
||||||
|
Pin 3: GPIO2 (Strapping - do not use)
|
||||||
|
Pin 4: GPIO3 (Strapping - do not use)
|
||||||
|
Pin 5: GPIO0
|
||||||
|
Pin 6: GPIO1 (GPS PPS - if used)
|
||||||
|
Pin 7: GPIO6
|
||||||
|
Pin 8: GPIO7 ← CS
|
||||||
|
Pin 9: GPIO8 ← MISO (DO)
|
||||||
|
Pin 10: GPIO9 ← CLK (SCK)
|
||||||
|
Pin 11: GPIO10 ← MOSI (DI)
|
||||||
|
Pin 12: GPIO26 ← CD (optional)
|
||||||
|
Pin 13: GPIO25 (GPS PPS - if used)
|
||||||
|
Pin 14: 5V (do not use - too high voltage)
|
||||||
|
Pin 15: GND ← GND
|
||||||
|
Pin 16: NC (No connection)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Important Notes
|
||||||
|
|
||||||
|
⚠️ **Warnings:**
|
||||||
|
- **Use 3.3V ONLY** - Do NOT connect to 5V (Pin 14) - this will damage the microSD card!
|
||||||
|
- ESP32-C5 does not have SDMMC host; SPI mode is required
|
||||||
|
- CD is optional: LOW = inserted, HIGH = removed (with pull-up)
|
||||||
|
|
||||||
|
## Current Configuration
|
||||||
|
|
||||||
|
The firmware is configured for **SPI mode** using:
|
||||||
|
- CLK: GPIO9
|
||||||
|
- MOSI: GPIO10
|
||||||
|
- MISO: GPIO8
|
||||||
|
- CS: GPIO7
|
||||||
|
- CD: GPIO26 (optional)
|
||||||
|
|
||||||
|
## Testing
|
||||||
|
|
||||||
|
After wiring, the firmware will automatically detect the SD card on boot. You should see:
|
||||||
|
```
|
||||||
|
I (xxx) sd_card: Initializing SD card via SPI...
|
||||||
|
I (xxx) sd_card: SD card mounted successfully at /sdcard
|
||||||
|
I (xxx) sd_card: SD card ready: XX.XX MB total, XX.XX MB free
|
||||||
|
```
|
||||||
|
|
||||||
|
If the card is not detected, check:
|
||||||
|
1. All connections are secure
|
||||||
|
2. Card is properly inserted in the breakout board
|
||||||
|
3. Card is formatted (FAT32)
|
||||||
|
4. Power supply is stable (3.3V)
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
**Card not detected:**
|
||||||
|
- Verify VCC is connected to 3V3 (Pin 1), NOT 5V
|
||||||
|
- Check GND connection
|
||||||
|
- Ensure card is properly seated in the breakout board
|
||||||
|
- Try a different microSD card
|
||||||
|
|
||||||
|
**Initialization fails:**
|
||||||
|
- Card may need formatting (FAT32)
|
||||||
|
- Check for loose connections
|
||||||
|
- Verify GPIO pins are correct
|
||||||
|
- Some cards may not work in SPI mode - try a different brand
|
||||||
|
|
||||||
|
**File system errors:**
|
||||||
|
- Card may be corrupted - reformat as FAT32
|
||||||
|
- Check card capacity (very large cards may have issues)
|
||||||
|
- Ensure proper power supply
|
||||||
|
|
||||||
|
**CD always shows REMOVED but card works:**
|
||||||
|
- Your breakout or slot may not support Card Detect (CD pad may be unconnected). Disable CD: menuconfig → ESP32 iperf Configuration → SD Card → Card Detect GPIO = **-1**.
