Summary:
This is the updated version for Darwin AIO. We integrated the ELRS receiver on the FC to make it easier to apply to the mini Drone. ESC adopts Bluejay firmware and is compatible with 1-3S Lipo input, and the maximum current reaches 17A.FC provides 2 sets of Uarts interfaces and at the same time provides various external devices interfaces such as SBUS, Softserial, CTR, BUZZ, RGB and so on , which perfectly solves the problem of insufficient quantity of F411 Uarts.

lass range and latency. It achieves this using a highly optimized over-the-air packet structure, giving simultaneous range and latency advantages.
