STorM32 v2.x Boards

The STorM32 v2.4 main board provides two types of NT bus ports, the NT and NT-X ports, which in addition are also different from the NT bus connectors found on the NT modules in as much as they have swapped Rx, Tx pins.

Comment: The Rx, Tx pins on the STorM32 board must be connected to the Tx, Rx pins on the NT modules.

STorM32 v1.x Boards

On the STorM32 v1.x main boards, the I2C plug is used as NT bus connector, with the pin assignments as shown below.

Comment: The Rx and Tx pins on the STorM32 board must be connected to the Tx and Rx pins on the NT modules. This needs a "crossing" of the Rx, Tx lines for the v1.x boards, see also the diagram in What is STorM32 NT about?

Comment: If starting from a "classic" (non-NT) STorM32 gimbal kit with an I2C IMU module, it is usually necessary to rewire existing cables to match the pinout of the NT bus.

CC3D Atom STorM32 Board

Since firmware version v2.27 it is possible to use a Atom CC3D as STorM32 main board. The Flexi Port plug is used as NT bus connector, with the pin assignments as shown below. Further information on the CC3D Atom can be found here.
