**Hardware:** (board / drone / SKU, serial # if you have it): M0041, M0173

**Software version:** (paste the output of `voxl-version`): 

**Configuration / services:** (paste the output of `voxl-inspect-services`)

**What I am trying to do:** : 
**1. Current Sensor on the M0041 Board**
Could you provide the part number of the current sensor used on the M0041 board? Also, what I2C slave address is configured for this sensor on the board?
**2. Connector Pinout on the M0173 Board**
Could you provide the signal name for each pin of the M0173 board connector highlighted in the image below? We would specifically like to know which pins carry the SPI signals.
