STorM32 Boards

At present, three different versions of STorM32-BGC boards are around.

Comments:

• The boards can in principle be populated with different microcontrollers; below the "typical" configuration is mentioned.
• To avoid confusion/missunderstandings please note: The boards provide many features hardware-wise, but not all are however currently supported by the firmware.

STorM32-BGC v1.2

STorM32 BGC board v1.2

MCU: STM32F103RC Motor drivers: TC4452VMF on-board Bluetooth (optional) on-board 6DOF IMU (MPU6050) IR led Futaba S-Bus Spektrum satellite up to seven PWM/Sum-PPM inputs/outputs joystick for each axis additional I2C port (I2C#2) 2 auxiliary ports BUT port

max. voltage: 18 V or 4S max. current: not yet fully exploited, depends also on motor driver package (SO08 or DFN8) with the DFN packages, motors with resistances of 15 Ohm or larger are easily handled, it is expected that also motors with 10 Ohm or larger can be handled

STorM32-BGC v1.1

differences to the v1.2 board:

• no Futaba S-bus support
• Spektrum satellite is supported, but no extra Spektrum connector on board

Comments:

• The order of pins on the I2C#2 port is reversed to that on the I2C#1 port; please consider this then connecting an MPU module to this port.

STorM32-BGC v0.17/v1.0

• MCU: STM32F103RB

Comments:

• The location of the pins needed to flash the firmware via an USB-TTL adapter is different here. Namely:

RC-GND = GND -> connect it to GND on the usb-ttl adapter

RC-1 = Uart1-Tx -> connect it to Rx on the usb-ttl adapter

RC-2 = Uart1-Rx -> connect it to Tx on the usb-ttl adapter
