Botlab Dynamics BotWing F722 FC + BotDrive 55A AM32 4-in-1 ESC Stack

Botlab Dynamics' BotStack pairs the BotWing F722 flight controller with the BotDrive 55A AM32 4-in-1 ESC on a 30.5x30.5 mm footprint for 2–6S builds. The FC follows a solderless, plug-in design with Betaflight-standard connectors, and the stack targets 5-inch freestyle, heavier freestyle rigs and long-range quads flown on Betaflight or INAV. Botlab Dynamics designs and manufactures its drone electronics in India.

Key features

• STM32F722 MCU with an ICM42688P gyro, AT7456E OSD chip and 32 MB blackbox flash

• DPS310 barometer plus I2C pads (SDA/SCL) for an external magnetometer, useful for INAV altitude hold and GPS navigation

• BotDrive ESC rated 55 A continuous and 60 A burst per motor, running AM32 on an AT32F421 MCU

• DShot300/600 and PWM motor protocols, with a built-in current sensor and VBAT output to the FC

• Firmware target BOTWING F722 in Betaflight and INAV, with a boot button for DFU flashing

• Connects a GPS, ELRS or SBUS receiver, DJI air unit and LED strips (5 LED pads)

Check that your frame takes a 30.5x30.5 mm stack and solder the low-ESR capacitor across the ESC battery pads. The 55 A per-motor rating leaves headroom for 6S 5-inch freestyle and heavier freestyle rigs.
