Well… I am working on a Nordic project…
Right now I connect to it over my phone on Bluetooth and I can turn the motor on and off that’s attached to it.
I’m writing a driver for it because one doesn’t exist yet to also run the ws2812 chain… it also has an IMU on board.
It would be a challenge but you can take the reference design from seed for the NRF 54l15 and build a whole ultra low power drone co controller to run alongside an ESPrunning Ardpilot.
I bet those chips paired on a board and talking over i2c would be a very powerful combination.
