Aikon F4

Description

FC with no PDB aimed at multi-rotor and fixed wing use, Aikon F4 features a carefully-chosen timer design which allowed to run 4-6 motors with burst DSHOT with maximum efficiency. On board are dedicated pads for ESC telemetry, VTX and camera control. Board also features an 11-pin connector for plug-and-play connection with Aikon AK32 4in1 ESC, providing voltage, current and ESC telemetry reading with no additional wires.

Features

UART3 inverter is controllable by software, you can use the SBUS pad for any unidirectional protocol by setting serialrx_inverted accordingly. There's also a solder-jumper to bypass the inverter and connecto UART3_RX to DSMX pad directly.

Software serial is preconfigured by default, all you have to do is enable SOFTSERIAL1 for VTX control and SOFTSERIAL2 for ESC sensor on the Ports tab in Configurator.

FAQ & Known Issues

  • First revision has no diode protecting the 5V input on the 11-pin ESC connector, make sure to pull the 5V wire coming from our ESC in order to avoid two regulators fighting against each other
  • First revision has RX4 (ESC Telemetry) and GND pad silkscreen swapped near motor outputs Aikon F4 top Aikon F4 bottom
