Revision as of 12:40, 22 March 2014

At present, three different versions of STorM32-BGC boards are in use (the v0.17/v1.0 seems not to be in used anymoe).


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 currently supported by the firmware.

STorM32-BGC v1.3

  • 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)
  • 3 auxiliary ports
  • BUT port
  • supply voltage: 6 - 18 V or 2 - 4S
  • motor current: max. 1.5 A per motor
    comment: this is not yet fully exploited and depends also on the motor driver package (SOIC or DFN); for DFN packages, motors with resistances of 15 Ohm or larger have been tested to be easily handled at 4S, it is expected that also motors with 10 Ohm or larger are handled well (for more details see here).


STorM32-BGC v1.2

STorM32 BGC board v1.2 with motor drivers in DFN package

Differences to the v1.3 board:

  • voltage regulator: smaller SOT223 package
  • only 2 auxiliary ports

STorM32-BGC v1.1

STorM32 BGC board v1.1 with motor drivers in SOIC package

Differences to the v1.2 board:

  • no Futaba S-bus support
  • Spektrum satellite is supported, but no extra Spektrum connector on board
  • no extra USB voltage protection diode
  • voltage regulator: smaller SOT223 package
  • only 2 auxiliary ports

Comment: 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

Differences to the v1.2 board:

  • MCU: STM32F103RB
  • motor drivers: only TC4452VAO in SO08 package
  • no IR led support
  • only three PWM/Sum-PPM inputs/outputs
  • no Futaba S-bus support
  • Spektrum satellite can be supported, but no extra Spektrum connector on board
  • no additional I2C port
  • no reverse voltage protection on the v0.17 board
  • voltage regulator: smaller SOT223 package
  • only 2 auxiliary ports
  • pin assignment on RC port different

Comment: 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
