PDF icon Manual202.86 KB

The latest tekko32 50A 4in1 (F4 Revision) ESC has got some improvements on its performance:

  • Current rating up from 45A to 50A
  • New and faster F4 MCU @ 150Mhz (compared to F3 @108Mhz & F0 @48Mhz)
  • PWM output up to 96K (default 48K)
  • The PCB design uses a design in which the drive circuit and the control circuit are separated. This design broadens the overcurrent capability of the drive circuit, and at the same time reduces the electrical interference to the control circuit.

Holybro's Tekko32 50A 4-in-1 ESC features an F4 MCU to give smooth operation and quick response. It supports 50A continuous current and up to 60A burst, making it compatible with most 5-6inch racing drone setups, even up to 6S. The ESC is the 4-in-1 that features in Holybro's F7 HDV Stack for the DJI HD FPV System; it can also be used with other FCs too. The layout of the PCB is very logical and with large contact pads it's also easy to solder.

For 6S setups please use the included extra low ESR 35V capacitor. This can be attached to the dedicated + / - pads on top of the ESC.


  • F4 MCU runs double faster than F051
  • 32bit ESC with BLHELI32 firmware
  • 4-in-1 ESC with 30.5x30.5mm mounting holes
  • Added more CAPS to reduce power noise
  • 4S – 6S LiPo Input
  • 50A Continuous Current Rating, 60A Bursts (10 seconds)
  • Supports Oneshot / Multishot / Dshot PWM / DSHOT 1200 / Damped light
  • Separate current sensors for each motor, Voltage output (VBAT), ESC Telemetry (TELEM)
  • No BEC
