Product overview
The GEPRC CEP-STABLE 12A Whoop Stack combines the GEP-12A-F4 flight controller and GEP-VTX200-Whoop video transmitter for small indoor Whoop and toothpick builds. Its flight control hardware uses an STM32F411 processor, an SPI-connected MPU6000 gyro/accelerometer and BetaFlight OSD with an AT7456E chip. The 28.5×28.5mm board has a 25.5×25.5mm M2 mounting pattern, defining the installation space required in a compatible frame. Power provisions include a 5V@1A BEC and integrated LC filter. The ESC specification lists 12A continuous current, 2–4S LiPo input and support for Dshot600, Oneshot and Multishot; no barometer is fitted.
The included video transmitter provides 5.8GHz operation across five bands and 48 channels, including Raceband, with selectable Pit, 25, 100 and 200mW output settings. It accepts 4.5V–5.3V, has typical current consumption of 300mA and weighs 2g without its antenna. An RG178 antenna with a U.FL interface, PAL/NTSC video support and IRC Tramp control define its video integration requirements. Receiver support includes the named Frsky, Futaba, DSM/DSMX, FlySky, TBS Crossfire and AC900 options, plus most SBUS receivers. The supplied electronics package contains both modules, a power cable, eight screws and four soft silicone pieces.
