Holybro FETTEC FC-G4 Stacks
Updated:New Rev1.7Recommending method: https://gui.fettec.net/FC/index.html Description: The Holybro FETtec FC G4 features the latest STM32 G4 MCU with math accelerator for the ultimate in-flight performance, onboard OSD for KISS flight tuning, 2 dedicated BECs for 5V and 16V switchable power, DSHOT2400 outputs for support of up to 8 motors, and dual 20x20 and 30x30 mounting holes. Note: Currently, the Holybro Fettec FC G4 does not support BLHeli_32 ESC Configuration via FC Passthrough and BLHeli_32 ESC telemetry/current reading. An Betaflight Flight Controller is needed to configure BLHeli32 ESC Setting.

Features: New & faster F4 MCU @ 150Mhz (compared to F3 @108Mhz & F0 @48Mhz) PWM output up to 96K (default 48K) Separate drive & control circuit, this broadens the current capability of the drive circuit while reducing the electrical interference to the control circuit. Specification: Continuous Current: 50A x4 Burst Current: 60A x4 Supports 4-6S battery Supports DShot 150/300/600/1200 & MultiShot/OneShot/Proshot/PWM etc. ESC telemetry Supported Onboard analog current sensor No output BEC BLHeli_32 firmware 1000uf 35v capacitor included (highly recommended for 6s setup) Dimensions: 45x37x6mm / Weight: 13.8g Mounting holes: M4 30.5×30.5mm (M3 grommets included) PIN MAP: Tekko32 F4 Metal 4in1 65A ESC F4 MCU @150Mhz / Metal-Cased MOSFET / PWM output up to 96K / 4~6S / BLHELI32 The all new Tekko32 Metal is the first 4in1 ESC in the market to adapt the fast F4 MCU. Powerful & reliable metal-cased MOSFET 4in1 ESC with smooth control and quick response. Features: New & faster F4 MCU @ 150Mhz (compared to F3 @108Mhz & F0 @48Mhz) PWM output up to 96K (default 48K) Metal-cased MOSFET for excellent heat dissipation Massive on-board capacitance for noise filtering at 2068uf 3 oz copper PCB design to allow bigger current and better heat dissipation Separate drive & control circuit, this broadens the current capability of the drive circuit while reducing the electrical interference to the control circuit. Specification: Continuous Current: 65A x4 Burst Current: 75A x4 Supports 4-6S battery Supports DShot 150/300/600/1200 & MultiShot/OneShot/Proshot/PWM etc. ESC telemetry Supported Onboard analog current sensor No output BEC BLHeli_32 firmware 1000uf 35v capacitor included (highly recommended for 6s setup) Dimensions: 43 x 44mm / Weight: 15.8g Mounting holes: M4 30.5x30.5mm (M3 grommets included) Note: Air flow for the ESC is very important if you want to run this 4in1 in high current. The battery wire (from Lipo to 4in1 ESC) should be at least 12AWG and well soldered.
