"Original" STorM32 Boards

At present, board versions v6.2 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 v3.3 and v6.2 STorM32 boards have 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 v6.2


  • 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.
