GEPRC GEP-20A-F4 AIO toothpick flight controller

GEPRC is the second manufacturer, who has released the 20A capable toothpick flight controller (the first was BetaFPV 20A F4 AIO) . GEP20A-F4-AIO board is rated for 20A continuous current and even 30A on peak (burst)! The MOSFETs on the board are TOSHIBA TPN2R203NC, that are capable of providing max 45A of the current. The board has no connector sockets, just solder pads for motor wires. And that is reasonable decision as the currents are high and the board is intended to be used with bigger motors on 3″- 4″- 5″ inch toothpicks.
