Revision as of 12:51, 3 July 2015
The technical specifications of various STorM32 boards are presented. For suppliers/vendors please refer to Where to buy STorM32 boards. For a detailed description of the various connectors on the boards see Pins and Connectors.
"Original" STorM32 Boards
At present, the versions v1.1, v1.2, and v1.3 are in use (v0.17/v1.0 boards are deprecated). Their commonality is a resistive voltage regulator and the TC4452 motor drivers.
Comments:
- The boards can be populated with different motor drivers, namely TC4452 driver in DFN package or TC4452 driver in SOIC package; the DFN package allows somewhat higher motor currents. To date (25.June.2015) all commercially available boards have the DFN package.
- The boards can in principle be populated with different micro controllers; the standard configuration is a STM32F103RC.
STorM32-BGC v1.3
STorM32-BGC board v1.3 with motor drivers in SOIC package
STorM32-BGC board v1.2 with motor drivers in DFN package
STorM32-BGC board v1.1 with motor drivers in SOIC package
- MCU: STM32F103RC at 72 MHz
- motor drivers: TC4452
- voltage regulator: linear resistive
- 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 ports for all three axes
- 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 also depends on the package, with DFN packages motors with resistances of 12 Ohm or larger have been tested to be well handled at 4S, motors with 10 Ohm may be handled with care; for the latest summary see here (for details see also here, here), here and here).
- board dimensions: 50 mm x 50 mm, 45 mm bolt to bolt, holes Ø3 mm
|
STorM32-BGC v1.2
Differences to the v1.3 board:
- voltage regulator: smaller SOT223 package
- only 2 auxiliary ports
STorM32-BGC v1.1
Differences to the v1.3 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
WARNING: The pins of connector I2C#2 are in reverse order to those of connector I2C, which implies also reversed voltage polarity. Pay attention to that before connecting a second IMU to the I2C#2 port.
Descendants
The STorM32 boards listed here are based on/derived from the layout of the "original" board designed by Martinez and OlliW, but modified in some ways.
GLB STorM32 v1.31
STorM32-BGC board v1.31 with DRV8313 motor drivers
- MCU: STM32F103RC at 72 MHz
- motor drivers: DRV8313
- voltage regulator: switched step-down
- 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 ports for all three axes
- additional I2C port (I2C#2)
- 3 auxiliary ports
- BUT port
|
- supply voltage: 9 - 25 V or 3 - 6S (according to the specs given by GLB, not yet confirmed in practice)
- motor current: 1.5 A
Comment: The board uses the same motor drivers as the BaseCam SimpleBGC 32-bit board, and the same spec can hence be expected, but the real capability has not yet been tested in practice.
- board dimensions: 50 mm x 50 mm, 45 mm bolt to bolt, holes Ø3 mm

Witespy STorM32-BGC v1.1 Mosfet Version
Witespy STorM32-BGC v1.1 board with mosfet motor drivers
- MCU: STM32F103RC at 72 MHz
- motor drivers: mosfet
- voltage regulator: linear
|
- supply voltage: ? (no specs given by witespy)
- motor current: ? (no specs given by wiitespy)
- board dimensions: 50 mm x 50 mm, 45 mm bolt to bolt, holes Ø3 mm

Comment: The info given on some pages is definitely wrong in some aspects. What we know so far (see also here and followup posts:
- the DRV8313 motor drives do not allow 2S operation
- only the RC port is available
- SBus is not supported
- it can be doubted that a BT module can be installed on board
