Product overview
The GEPRC STABLE 20A Toothpick Stack AIO combines an AIO brushless flight controller and ESC assembly with a separate GEP-VTX200-Whoop video transmitter for toothpick FPV micro quad builds. Its 32 × 32mm controller board uses a 26.5 × 26.5mm M2 mounting pattern, defining the space and attachment points needed in the frame. GEPRC recommends 12XX–15xx motors with 3–4-inch propellers. The controller accepts 2–4S LiPo input and specifies 20A continuous current and 30A peak current.
Flight control uses an STM32F411 MCU and an SPI-connected MPU6000 gyro/accelerometer, with Betaflight OSD, current monitoring, external buzzer and LED support; no barometer is fitted. The video transmitter provides switchable Pit/25/100/200mW output, PAL/NTSC video and IRC Tramp control, and requires 4.5V–5.3V input. Its stated 2g weight excludes the antenna. Supplied equipment comprises one GEP-20A-F4, one GEP-VTX200-Whoop, a power cable, eight screws and four soft silicone pieces, making this an electronics package for integration into a quad build.
