This page provides diagrams of the many connections on the STorM32 boards.
The STorM32 connections are grouped into ports. A port consists typically of one or more pins, a Gnd pin and possibly a 3.3 V or 5 V pin. The pins of a port are labeled by the port name plus a number (e.g. AUX-0 refers to the pin 0 on the AUX port) or by its commonly known function (such as Gnd, 3.3 V, Tx, Rx, SCL, SDA etc.). Some pins can serve multiple purposes, e.g., pin RC-0 can serve also as Futaba S-Bus input, as CRSF input or as UARTX-Rx.
For a general description of the ports and pins see Ports and Pins by Function. For the details of their function and usage please consult the other wiki pages.
Except of the ports POT, BUT and UART2/ESP all ports are 5 V tolerant, which means that you can apply signals with voltages of up to 5 V to their pins without damaging the board. The ports POT, BUT and UART2/ESP are however not 5 V tolerant. The voltage on the POT, BUT and UART2/ESP pins must not exceed 3.3 V.
The 3.3 V and 5 V pins must only be used as supply. Never apply any voltage to a 3.3 V or 5 V pin (unless you're an expert and know what you do).
STorM32 v4.1 Board
The STorM32 v4.1 main board provides two types of NT bus ports, the NT and NT-X ports. They both are 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 of the NT and NT-X ports on the STorM32 board must be connected to the Tx, Rx pins on the NT modules.
On the bottom side of the board is located the JP1 solder bridge (not visible in the picture below). When closed: The motor drivers are connected to VBat and are powered, and can be used. The voltage shall then not exceed 12 V or 3S. When open: The motor drivers are disabled and non-functional, and the voltage can be up to 27 V or 6S.
Comment: The board shown in the picture is a pre-release version.
STorM32 v3.3 Board
The STorM32 v3.3 main board provides two types of NT bus ports, the NT and NT-X ports. They both are 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 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 STorM32 boards have no motor drivers on-board, i.e., NT motor modules are needed in addition.
Comment: The CAN port is obsolete, and not supported anymore since firmware v2.57e.
Micro STorM32 v3.3 Board
The v3.3i Micro STorM32 board provides the same connections as the v3.3 Board (with the exception of the USB port), but exposes them as solder pads.
The Micro STorM32 board is designed to be stackable with other extension boards, such as USB, power, motor, logger boards, see e.g. the rcgroups post here.
Comment: The v3.3 Micro STorM32 board has no motor drivers on-board, i.e., NT motor modules are needed in addition.
STorM32 RaspberryPi Hat v3.3
The v3.3i STorM32 RaspberryPi Hat provides the same connections as the Micro STorM32 v3.3 board, but in RaspberryPi micro-Hat form factor. The hat is designed to be compatible with the extension boards of the Micro STorM32 series. In addition it provides an EEPROM as required by the RaspberryPi Hat specification (not populated in the picture). Furthermore it provides a dual UART expansion module, and some more connections with the RaspberryPi GPIOs.
STorM32 v1.x Boards
On STorM32 v1.3x main boards, the I2C plug is used as NT bus connector, with the pin assignment as shown below.
The scheme below refers to a v1.3 board. The pins of the v1.31 board are identical to that of the v1.3 board.
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.
Comment: v1.1 and v1.2 boards are deprecated and not supported anymore. The v1.2 board run the firmware for the v1.3x board, with only few caveats.
