@rogerli said in Unable to communicate with add-on board:
@Vinny I have another VOXL2 where only DS1 and DS2 lights up constantly, but D1 doesn't light up. Is this normal? (There was a slight deformation near the power interface due to a previous fall.)
@tom The SDK version of the VOXL2 that I'm using is 1.1.3.
I initially bought two VOXL2 boards, both version 1.1.2. One was deformed due to a crash, but the other still works well. Later, I purchased two more VOXL2 boards, which arrived with version 1.1.3. One of them was completely non-functional, and the other also had communication issues. Due to time constraints, we urgently ordered two more VOXL2 boards. Should we downgrade the SDK to 1.1.2 for safety? Currently, as we are in the pre-mass production stage and sending products for inspection, we cannot afford sudden failures of critical components.
