Revision as of 15:43, 11 June 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.
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.
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 packageSTorM32-BGC board v1.2 with motor drivers in DFN packageSTorM32-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)

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
