The technical specifications of various STorM32 boards are presented, as far as they are known. To find suppliers/vendors please go to Where to buy STorM32 boards. For a detailed description of the various connectors on the (original) boards see Pins and Connectors.
"Original" STorM32 Boards
At present, board versions v1.3, v3.3 and v4.1 are in use and supported (v0.17/v1.0, v1.1, v1.2 and v2.4 boards are deprecated).
- The characteristic of the v1.3 board is a linear voltage regulator and on-board TC4452 motor drivers.
- The v3.3 board is specifically designed for NT and especially T-STorM32, and is available in different form factors. It is distinguished by a low-noise 5 V switching voltage regulator and a 2nd UART2 port, but it has no motor drivers on board.
- The v4.1 board combines, so to say, the v1.3 and v3.3 boards; it is designed for NT and T-STorM32 but also provides DRV8839 motor drivers on board.
STorM32-BGC v4.1
|
|
Comment: This board is design of KrattWorks, [1].
STorM32-BGC v3.3m, v3.3i
|
|
Comment: The v3.3m version has a MPU9250 on-board IMU and the v3.3i version has a ICM42605/ICM42688P/ICM42688V on-board IMU.
Comment: This board has no motor drivers; NT motor modules are thus mandatorily required.
Micro STorM32-BGC v3.3i
|
|
Comment: This board has no motor drivers; NT motor modules are thus mandatorily required.
Comment: Also the STorM32 Raspberry Pi Hat v3.3i exists, which is essentially the Micro board in different form factor with some additional peripherals useful for Raspberry Pi applications.
STorM32-BGC v1.3
|
|
Comment: This board was designed in cooperation with Martinez.
Descendants
The STorM32 boards listed here are designs of third parties, which are based on or derived from the "original" board designs, but modified in some ways.
Ensys STorM32 v3.3
|
|
Comment: This board has no motor drivers; NT motor modules are thus mandatorily required.
GLB STorM32 v1.31
|
|
Comment: The 3.3V power on this board seems to be quite weak, and has caused repeatedly issues with powering NT modules. One single NT IMU seems to be ok, but not more. See also [[2]].
Comment: There had been cases with a problem with EMI noise on the 433/915 MHz band from this board, see [[3]]. For solutions see [[4]]. EMI noise seems not to be a problem in general, however, see [[5]].
STorM32 v1.32
|
|
Comment: For NT setups this board might be preferred over the v1.31 board, since it uses the same linear regulator as the v1.3 and not the weak switching regulator of the v1.31. For older I2C-based setups 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. The STorM32 boards listed here are independent designs by third-parties.
Micro STorM32 BGC
|
|
Comment: This board is suitable only for 2S (see [[6]]), with higher voltages it gets quite hot and may malfunction. Read also this: [[7]]. 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.
GLB Mini STorM32 BGC

AliExpress Mini STorM32 BGC
|

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
- only the RC port is available
- SBus is not supported
- BT module cannot be installed on-board
