RB5 3rd part ESC support

[benjamin linne]

Hey, are there any plans to support 3rd party ESCs with the RB5? Specifically blheli ESCs with DShot support. I'm looking for ESCs that are capable in the 100A range and heard there was some progress being made in . I like the reduced wiring with the modalAI ESC since it uses a single UART, so if there are other compatible ESCs with a higher amperage rating, I'd be interesting in learning about them.

Hi @benjamin-linne,

Supporting more ESCs in the future is definitely on the roadmap, but no hard timelines to provide.

In general, the current ESC is interfaced with a UART based driver, eg. here:
https://github.com/modalai/px4-firmware/blob/v1.2.x-modalai-rb5-flight-alpha/src/drivers/uart_esc/modalai_esc/modalai_esc_serial.cpp#L50

This UART itself actually resides in the DSP, so it's customizable but we need to get a bit more docs up for this to make it achievable for others!
