F Series ESC

Outline of the APD F_Series ESCs.
Operating on a genuine STM32F3 processor ensures no input commands are missed, even at the highest input update rates. Its bleeding-edge features include PWM-frequency dithering to ensure the smoothest control at high power, whilst maintaining maximum efficiency.


Version 1 vs Version 2 Variations

As part of our commitment to delivering top-notch products, we have diligently worked on improving the F_Series ESCs. We're excited to announce the release of our latest V2 hardware, which features some notable enhancements. These improvements include a built-in bootloader for configuration, passthrough firmware updating from a supported flight controller, Bi-Directional DShot (supported units), and UART pin overvoltage protection (supported units).
We have designed the V2 F_Series ESCs to be a drop-in replacement for the existing units, ensuring a seamless transition for our customers. There is no requirement to firmware update V2 units once delivered to introduce the following features.

Version 2 Improvements

The following improvements have been made to the version 1 variations:
  • All units:
    • Configuration of drive parameters, signal types and fault handling.
    • On board bootloader.
    • Additional Telemetry types: PWM Telemetry and RPM Output.
    • High-speed telemetry rates (digital protocols).
    • Reversible drive mode operation support (full forwards to full reverse).
    • Dynamic signal quality checks across supported input protocols.
  • 80F3[X]v2 and 120F3[X]v2:
    • Bi-Directional DShot for RPM Filtering support.
    • Passthrough firmware updating and configuration.
    • Hardware protection for UART programming pins.

Unit Identification

The V2 variation units are designed to be a drop-in replacement over the V1 counterparts, for minimum system-level changes. The PCB model number is visible for unit identification, as can be seen in the example below.
