That is by design: * Four PWM pins on two independent TC channels * Five interrupt pins (two can wake from backup mode) +![image](/images/sensor-board-pinout.png) + These tiny “sensor boards” have a set outline, and the available area for your electronics is quite small (5.7 × 5.7 × 1 mm). Still, this is plenty of room for an environmental sensor, MEMS accelerometer or magnetometer and a couple of decoupling capacitors. Note that you will likely be limited to QFN and LGA type parts; SOICs are too large, and even SSOP packages are generally too thick. You can find reference designs for several sensor boards in the `PCB/Sensor Boards` directory within this repository. Getting code on the watch |
