Hello, I am using voxl2 new SDK 1.0.0. I want to understand integration of i2c device to apps-processor. I am looking to integrate PCA9685 PWM driver IC with voxl2. I am aware of using J3 and J5 on VOXL2 to expose i2c bus for integration. But in my current architecture we need to use Microhard add-on board over B2B interface on voxl2, so how to enable i2c bus over Microhard add-on board? Is it possible?

@ Aaky Depending on what you are trying to do with the PCA9685 you could use the PX4 driver and the spare i2c port coming from the DSP on J19

@Eric-Katzfey Thanks for the information. The add on board is Microhard modem B2B board without any Microhard radio in it acting just as USB port provider for my doodle labs modem. How can I get UART port if I am using this board?

@Aaky The Microhard board does not expose an apps processor UART but you could use a USB to UART adapter to connect to the Gimbal via one of the USB ports.
