Hi again,
I have an optical flow sensor that needs SPI and I2C to work, most flight controllers don’t have an SPI port. Is it it possible to use an arduino to send the optical flow data via telemetry to the FC, an arduino has 1x SPI, 1x I2C and 1x UART (using an ESP-01 for the telemetry).
This is the optical flow sensor I have (https://www.bitcraze.io/products/flow-deck-v2/)
Thanks
