## V1.1
|
|
**Release Date:** Late 2023
|
|
|
|
### Changes:
|
|
- **Fixed:** Power loss issue affecting the GNSS module during LoRa operation
|
|
- **Enhanced:** Low-power functionality
|
|
- **Added:** Additional LDO to supply power to the UC6580 GNSS module independently
|
|
- **Changed:** GNSS control pin removed; GPIO 3 set to `HIGH` enables GNSS power
|
|
|
|
### Key Differences from V1.0:
|
|
|
|
| Feature | V1.0 | V1.1 |
|
|
|---------|------|------|
|
|
| GNSS Power | Shared rail | Dedicated LDO |
|
|
| GNSS Control | N/A | GPIO3 |
|
|
| Power Isolation | Limited | Improved |
|
|
| Low Power Mode | Basic | Enhanced |

## Hardware Version Detection
|
|
|
|
To determine your hardware version programmatically:
|
|
|
|
```cpp
|
|
// V1.1 requires GPIO3 HIGH to enable GNSS
|
|
#define GNSS_CTRL_PIN 3
|
|
|
|
void setup() {
|
|
// For V1.1 hardware - enable GNSS power
|
|
pinMode(GNSS_CTRL_PIN, OUTPUT);
|
|
digitalWrite(GNSS_CTRL_PIN, HIGH);
|
|
}
|
|
```
