Useful Test Points
The Airsense S10 mainboard is covered in test points. Here are some that may be of interest.
| Pin | Description |
|---|---|
| STM32_3V3 | Core voltage for main uC. |
| GND | Ground. |
| SWDIO | Used to program and debug main uC. |
| SWCLK | Used to program and debug main uC. |
| SWO | Could potentially be used to get further debug output from main uC (TBD). |
| STM32_NRST | Reset pin for main uC. |
| PSENSOR | Scope this to get an analog pressure readout without external equipment. |
| STM8_UART | UART_TX from STM8 aux uC to main uC |
| STM8_3V3 | Core voltage for aux uC |
| STM8_SWIM | Single-wire programming and debug pin for aux uC |
