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) Comment: 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
