BetaFPV BMI270 Gyro F4 12A AIO ELRS 2.4G 1-2S (26X26mm) Brushless Flight Controller For 3″Toothpick BT-F4AIO12

BetaFPV BMI270 Gyro F4 12A AIO ELRS 2.4G 1-2S (26X26mm) Brushless Flight Controller For 3"Toothpick BT-F4AIO12

F4 1S 12A AIO Brushless Flight Controller V2.2 is the default FC for Cetus X brushless whoop quadcopter, also great for 85mm whoop drones like Meteor85 and 3" toothpick drones like HX115 SE Toothpick Drone and HX115 LR Toothpick Drone. We updated the FC to V2.2 with BMI270 gyro and BB51 ESC hardware in place of ICM20689 gyro and BB21 ESC hardware.

Bullet Point

• F4 1S 12A AIO Flight Controller is the best choice for building ultra-lightweight 3" toothpick drones like HX115 SE FPV Quad and 85mm whoop drones. Recommend Meteor85.
• Most of the 1S flight controllers on the market come with 5A ESC by now, but this FC especially integrates 1S 12A ESC, providing more sufficient power for 3" toothpick drones or 85mm whoop drones.
• Built-in current meter, 2 programmable RGB LEDs, and SPI ELRS. At the same time, all the pads are left for the external receivers with UART1 and UART2, for buzzers, etc.
• Large pads are reserved for solder motor cables, this design will make solder easier.

USB Port: SH1.0 4-Pin

Specification of 1S 12A ESC
Built-in ESC with 12A continuous and peak 25A current
Input voltage: 1S-2S
ESC firmware: C_X_30_48_V0.18.1.hex for Bluejay BB51 hardware
Signal support: D-shot150, D- shot300, D-shot600, Oneshot125, Multishot, PWM

The Bluejay firmware could support the BB51 hardware now.  ELRS boards are powered by BB51 hardware. If you want to setup the ESC specification, please use the BLHeliSuite16714902A_Beta or ESC-Configurator.

Note: Only SPI ELRS 2.4G version supports motor direction set through Betaflight Configurator and SPI Frsky version does not support it. BLHeli Configurator and Bluejay Configurator are invalid for the BB51 ESC (both versions).
