HGLRC Specter F411 12A AIO

The HGLRC Specter F411 12A AIO packs a flight controller, 4-in-1 ESC, 400mW video transmitter and ExpressLRS receiver onto a single 25.5x25.5mm whoop-format board, aimed at 2S-4S micro and toothpick builds.

Key features

• Integrated 400mW analog VTX and onboard ELRS receiver remove two separate modules from the stack, cutting wiring and weight.
• F411 processor paired with an ICM42688P gyro for low-noise sampling in Betaflight.
• 12A continuous 4-in-1 ESC runs BLHeli_S firmware, flashable to Bluejay for bidirectional DShot and RPM filtering.
• Rated for 2S to 4S LiPo, giving more headroom than 1S-only whoop boards.
• Standard 25.5x25.5mm mounting pattern drops into common micro and toothpick frames.
• Two spare UARTs, so plan external peripherals such as GPS or telemetry accordingly.

Specifications

• MCU: STM32F411
• Gyro: ICM42688P
• Input Voltage: 2S-4S
• ESC Current: 12A continuous
• ESC Firmware: BLHeli_S
• VTX Power: 400mW (integrated)
• Receiver: Integrated ELRS
• Mounting Size: 25.5x25.5mm
• UARTs: 2

Its all-in-one layout suits 2.5 to 3.5-inch toothpick and micro freestyle builds where you want a stack-free setup without adding a standalone VTX or receiver module.
