Happymodel CrazyF411 AIO (ELRS)

Overview:

The Happymodel CrazyF411 ELRS AIO board ships with an integrated UART based ELRS receiver and 20A 4in1 ESC - all on one board. The UART based ELRS receiver allows more convenient flashing then an SPI based receiver as its physically seperate on the board. It ELRS firmware can be upgraded over WIFI or via Betaflight pass-through. The 20A ESCS are most suited to toothpick style quads, this board shouldnt be chosen for a larger quad build where more appropriate high amperage ESCs should be chosen.
