Pins and Connectors

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. Look at wiring on this this page

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.

NT v1.x Modules

All NT v1.x modules have a 4 pin JST plug for the NT bus connector, with the pin assignments as shown below. They in addition offer a BOOT0 solder jumper, to allow for a first-time flashing. Some modules offer some further solder jumper for configuring them, some others expose also the SWD pins, and yet some others may provide access to additional extension pins.
