Socket Type C

Controller-area network (CAN, or CAN-Bus). Pins number 4 and 5 serve as the CAN transmit (TD) and receive (RD) pins, and double as general-purpose input/outputs. In addition, pins number 3 abd 6 are general-purpose input/outputs, and pin number 3 supports interrupt capabilities.

Legend:

CAN CAN signal pin.
GPIO

A general-purpose digital input/output pin, operating at 3.3 Volts.

(G)

In addition to another functionality, a pin that is also usable as a GPIO.

[UN]

Modules must not connect to this pin if using this socket type. Mainboards can support multiple socket types on one socket, as long as individual pin functionalities overlap in a compatible manner, so that a pin from one socket type can overlap with a [UN] pin of another.

! Interrupt-capable and software pull-up capable GPIO (the pull-up is switchable and in the range of 10,000 to 100,000 ohms).
+3.3V Connection to the +3.3V power net.
+5V Connection to the +5V power net.
GND Connection the power ground net.

Connector Pin Numbering

Pins numbers for the male 10-pin connector standard Gadgeteer socket, as seen from above. In most cases, the ribbon cables will have the pin 1 conductor marked in red.
