Overview
MAD Components BLHeli_32 70A 2-8S Drone ESC for brushless multirotor/FPV power systems. The provided materials state this BLHeli version is a beta build and cannot be updated, and that BLHeli32 service has stopped; with Betaflight 4.5 it cannot support bidirectional DShot. AM32 firmware versions are recommended by the manufacturer for future availability.
Key Features
- Continuous current: 70A
- Input voltage: 2-8S LiPo (also see the additional spec set below)
- Drive signal support: DShot150/300/600/1200, MultiShot, OneShot, PWM
- Current sensor: support
- Telemetry passback/backhaul: support
- Processor (image spec): STM32G071; integrated 3-in-1 driver
- Hardware notes (from image text): 8-layer PCB with 4*4*4*3OZ copper thickness (total thickness stated as 28OZ), TG-180 board, via-hole copper filling process
- Capacitors (from image text): 11 pcs TDK 22uF 35V low ESR (total capacity stated as 240uF)
- MOSFETs (from image text): Infineon “DirectFET” package, internal resistance stated as < 1mR
- Onboard RGB LED (from image text)
- Firmware notes (from image text): supports ESC parameter adjustment by flight controller (Betaflight 3.2.0 or above); includes “Damped Light” and regenerative braking function
