Product overview
The Happymodel Beecore VTX is a brushed flight controller for Tiny Whoop-style frames, with replacement applications covering Kingkongrc/LDARC Tiny6/6x/7/7x/8/8x models. Its board combines an STM32F303CCT6 MCU running at 72MHZ with 256K FLASH, an MPU-6000 sensor connected over SPI, and four high-current NMOS transistors with operating current of up to 10A each. The controller accepts a 1S battery input at DC 3.5-4.35V. Its 29mm*29mm board has mounting hole spacing of 26mm * 26mm and weighs 4.0 g.
Integrated FPV equipment includes Betaflight OSD and a 5.8G, 25mw, 40-channel video transmitter. The F3 MCU controls the OSD over the SPI bus in DMA mode, while SmartAudio allows VTX channel changes using the radio sticks. Receiver compatibility includes PPM, SBUS, IBUS, DSM2 and DSMX protocols, and the controller is heading LED ready. These flight-control, on-screen display and video-transmission functions are built into the Beecore VTX board for use in Tiny Whoop-style brushed builds.
