Overview
The Fiodel 4-in-1 ESC drives four brushless motors from a 6S pack at 60 A continuous per motor. Each motor channel is a complete controller of its own: an Artery AT32F421 microcontroller running AM32, a Texas Instruments DRV8300 three-phase gate driver and six Toshiba TPHR8504PL MOSFETs.
The power stage is built for clean switching. Every phase has its own RC snubber, every FET bank its own ceramic decoupling, and battery and phase current run on paired copper zones across eight 1 oz layers stitched by via arrays. A TVS diode guards the battery input, and a 470 µF capacitor is supplied to fit at the battery leads.
A TI INA190 amplifier on a 0.1 mΩ shunt reports total current to the flight controller as an analog voltage. Battery and motor wires solder into castellated pads that take solder from both sides. The flight controller connects through a 10-pin JST-SH socket in the Betaflight pinout, or through a matching row of solder pads.

Questions
- Which firmware does it run?
- AM32, on all four controllers. Settings are changed through the flight controller with any AM32 configurator.
- Does it work with flight controllers from other brands?
- Yes. The socket follows the Betaflight 10-pin ESC pinout and the same signals are on solder pads.
- Does it power my flight controller?
- It passes battery voltage through the 10-pin cable. Your flight controller needs its own regulators, as the Fiodel F405 has.
- When will it ship?
- This is a pre-order. Shipping starts end of November 2026, in the order pre-orders were placed. You can cancel for a full refund any time before your order is dispatched.
