STorM32-BGC v4.1
- MCU: STM32F103RC at 72 MHz
- motor drivers: DRV8839
- voltage regulator: 5 V, 2 A (??) switching regulator
- on-board IMU: ICM42688P/ICM42688V
- 2x NT port and 1x NT-X port
- UART2 port
- on-board USB-TTL adapter CP2102, permits flashing per USB
- USB-C connector

- joystick port for two axes
- 2 auxiliary ports, BUT port
|
- supply voltage: 6 - 12 V or 2 - 3S (with motor drivers enabled)
Comment: The motor drivers are enabled by closing the JP1 solder bridge. When the solder bridge is open, the board can be used with voltages up to 20 V or 4S (??).
- motor current: 1.0 A (??)
- board dimensions: 40 mm x 28 mm, 35 mm bolt to bolt, holes Ø3 mm

- voltage regulator: 5 V, 0.6 A low-noise switching regulator
- on-board IMU: ICM42605/ICM42688P/ICM42688V (v3.3i), or MPU9250 (v3.3m)
- 2x NT port and 1x NT-X port
- UART2/ESP port
- on-board USB-TTL adapter CP2102, permits flashing per USB
- Futaba S-Bus, CRSF, Spektrum satellite
- up to four PWM/Sum-PPM inputs/outputs
- joystick port for two axes
- 2 auxiliary ports, BUT port
- CAN bus port (obsolete, not supported anymore)

Comment: Tthe v3.3i version has a ICM42605/ICM42688P/ICM42688V on-board IMU, the v3.3m version has a MPU9250 on-board IMU.
Comment: This board has no motor drivers; NT motor modules are thus mandatorily required.
