Pins and Connectors

The info on this page refers to the STorM32bgc v1.3.

The STorM32bgc provides many connections, which are grouped into what shall be called ports. A port consists typically of one or more pins, a Gnd pin and possibly a 3.3V pin. The pins of a port are typically labelled by the port name plus a number, e.g. AUX-0 refers to the pin 0 on the AUX port, unless the pins are related to commonly known functions, such as Gnd, 3.3V, Tx, Rx, SCL, SDA and so on. Some few pins serve multiple purposes, such as e.g. the pin RC-0 which is also UART1-Rx.

The following ports are available:

MOT0, MOT1, MOT2

Function: These ports are the connectors for the motors. The yaw motor has to be connected to MOT2.

I2C

Pins: Gnd, SCL, SDA, 3.3V

Function: Connector for the external camera MPU module.

I2C#2

Pins: Gnd, SCL, SDA, 3.3V

Function: If an external 2nd MPU module shall be used instead of the on-board MPU, then it's connected here.

RC

Pins: Gnd, RC-0, RC-1, RC-2

Function:

RC2

Pins: Gnd, RC2-0, RC2-1, RC2-2, RC2-3

Function: RC PWM signals from e.g. RC recievers can be connected to here.

POT

Pins: Gnd, POT-0, POT-1, POT-2, 3.3V

Function: These three pins are connected to the analog digital converter (ADC) of the microprocessor and hence can digest analog signals. Typically potentiometers of e.g. a joystick are connected to here.

BUT

Pins: Gnd, BUT-0

Function: This pin is actually also connected to the analog digital converter (ADC) of the microprocessor, but the analog signal are processed differently than those on the POT port. Currently this port is used to connect a key to it.

AUX

Pins: Gnd, AUX-0, AUX-1, AUX-2

Function: These are general purpose pins. Currently they are used to connect keys to them.

Comment: on v1.2 and earlier bords this port has the pins Gnd, AUX-0, AUX-1, 3.3V

IR

Pins: Gnd, IR-0

Function: Allows to connect an IR led to remote control a camera.

UART

Pins: Gnd, Rx, Tx

Function:

SWD

Pins: SWDIO, Gnd, SWCLK, 3.3V

Function:
