"Original" STorM32 Boards

At present, board versions v6.x are supported (v0.17/v1.0, v1.1, v1.2, v1.3x, v2.4, v3.3, v4.1 boards are not supported).

The STorM32 boards offer two types of NT bus ports, the NT and NT-X ports. They both are different from the NT bus connectors on the NT modules in that they have swapped Rx, Tx pins.

Comment: The Rx, Tx pins of the NT and NT-X ports on the STorM32 board must be connected to the Tx, Rx pins on the NT modules.

Comment: The v6.2 STorM32 board has no motor drivers on-board, i.e., NT motor modules are needed in addition.

In addition to the boards shown here, also other variants exist, such as e.g. micro versions.

The design schemes are located in https://github.com/olliw42/storm32bgc

STorM32-BGC v6.3


  • MCU: STM32H7A3RG at 280 MHz
  • motor drivers: DRV8839
  • voltage regulator: 5 V, 2 A (??) switching regulator
  • on-board IMU: ICM42688P/ICM42688V
  • 2x NT port and 1x NT-X port
  • USB-C connector, VCP & DFU
  • UART2/ESP port
  • CRSF, Futaba S-Bus
  • up to four PWM/Sum-PPM inputs/outputs
  • joystick port (analog) for two axes
  • 2 auxiliary ports (digital), BUT port
  • supply voltage: 6 - 12 V or 2 - 3S (with motor drivers enabled)
    Comment: The motor drivers are enabled by closing the JP1 solder bridge (on the bottom side of the board). When the solder bridge is open, the board can be used with voltages up to 20 V or 4S (??).
  • motor current: 1.0 A (??)
  • board dimensions: 40 mm x 28 mm, 35 mm bolt to bolt, holes Ø3 mm

STorM32-BGC v6.2


  • MCU: STM32H7A3RG at 280 MHz
  • motor drivers: none
  • voltage regulator: 5 V, 2.0 A low-noise switching regulator
  • on-board IMU: ICM42688P/ICM42688V
  • 2x NT port and 1x NT-X port
  • USB-C connector, VCP & DFU
  • UART2/ESP port
  • CRSF, Futaba S-Bus
  • up to four PWM/Sum-PPM inputs/outputs
  • joystick port (analog) for two axes
  • 2 auxiliary ports (digital), BUT port
  • supply voltage: 6 - 27 V or 2 - 6S
  • motor current: depends on used NT motor modules
  • board dimensions: 40 mm x 25 mm, 35 mm bolt to bolt, holes Ø3 mm

Comment: This board has no motor drivers; NT motor modules are thus mandatorily required.
