Product overview
The BETAFPV Toothpick F4 2-4S AIO Brushless Flight Controller 12A(BLHeli_S) combines flight control, on-screen display and electronic speed control in a compact board for toothpick drones. It is an electronics component supplied with installation accessories. The board measures 32.5*32.5mm and uses a whoop mounting pattern with enclosed holes at 26.5*26.5mm spacing. Its weight depends on the pin configuration: 6.2g without pins or 6.5g with pins pre-soldered. Included rubber dampers support installation in builds with limited stack height.
Integration access is concentrated around the board edges, with a side-mounted USB connector and edge-positioned solder pads. Double-sided motor pads accommodate connector-based or directly soldered motor wiring, while the motor headers use 1.25mm connectors. Three complete UARTs provide integration space suitable for DJI HD video transmission. The controller also supports the specified external receiver families, programmable LEDs such as WS2812 and built-in current sensing. Its STM32F411CEU6 CPU operates at 100MHZ, paired with an MPU6000 six-axis sensor over SPI and an AT7456E OSD chip.
The ESC accepts 2S-4S LiPo input, with a continuous current specification of 12A and a peak specification of 15A. It uses BLHELI_S firmware and supports the listed PWM, Oneshot, Multishot and Dshot protocols. Battery selection should follow the corresponding recommended motor combinations because mismatched batteries and motors can compromise power and performance. The supplied package contains the controller, an XT30 pigtail, four M2x10mm screws, four M2 nuts and four rubber dampers. Four motor pluggable pins accompany the version without pre-soldered pins.
