== "Original" STorM32 Boards ==


Comments:
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.
* 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.

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.

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.

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.

Comment: This board cannot really be recommended; it's probably better to get a v1.31, which tends to be cheaper and especially offers a switching voltage regulator.

Third-Party Boards

The terms of usage of the STorM32 project allows, and in fact encourages, making own hardware, for both DIY and commercial purposes, without restrictions.

Micro STorM32 BGC

Micro STorM32-BGC board
  • MCU: STM32F103RC at 72 MHz
  • motor drivers: TC4452
  • voltage regulator: linear (LG33)
  • supply voltage: 7.4 - 16.8 V or 2 - 4S
  • motor current: 1.5 A (according to the given specs, whatever this means)
  • board dimensions: 40 mm x 22 mm, no mounting holes
  • no BOOT0 and RESET buttons

Comment: This board is suitable only for 2S (see [[1]]), with higher voltages it gets quite hot and may malfunction. Read also this: [[2]]. The board can only be flashed with a ST-Link adapter via SWD, it cannot be flashed via the "usual" procedure. Many pins/ports are not available. Overall, this board cannot be recommended, except for special applications.

Comment: The info given on some pages is definitely wrong in some aspects. What we know so far (see also here and followup posts):

  • DRV8313 motor drivers do not allow 2S operation
  • it is not clear which motor drivers this board uses, or if it in fact has motor drivers at all
  • only the RC port is available
  • SBus is not supported
  • it can be doubted that a BT module can be installed on board
