Board documentation
A compact, CM5-form-factor Electronic Speed Controller (ESC) powered by an STM32F051K8U6 MCU and FD6288Q motor driver, running AM32 firmware. Rated up to 6S and 60A, it features an integrated INA238 high-precision current sensor broken out to I2C, and supports convenient firmware flashing and debugging via an ST-Link V2 interface.
•Dimension: 55mm × 40mm
•Firmware: AM32_AM32REF_F051 (v1.99)
•Core: STM32F051K8U6
•Motor Driver: FD6288Q
•Power: Up to 6S LiPo and 60A continuous
•Form Factor: CM5 stackable layout
•Sensors: INA238 current sensor (I2C breakout)
•Programming: SWDIO & SWDCLK via ST-Link V2
•Shunt Resistor: 5W 0.5mΩ
•Onboard Bulk Capacitor Bank: 47uF
•External Capacitor Recommended: 400uF
•Onboard LDO Regulators: TS3480 (3.3V), HT75xx (5V)
•Power Regulation: Transitioning to a synchronous switching regulator for the 5V rail to significantly reduce heat dissipation and improve thermal efficiency.
•Interface & Testability: Replacing the 2.54mm header pins with optimized pogo pads for the SWD interface, reducing board footprint and BOM cost.
•Surface Finish: Upgrading to an ENIG (Electroless Nickel Immersion Gold) coating to ensure durable, oxidation-free contact surfaces for reliable pogo-pin programming and probing.
•Telemetry & Feedback: Adding an onboard WS2812 addressable RGB LED for visual status and diagnostic feedback.
