Schematic and Expansion Connectors¶
It’s easy to expand your CodeX with external hardware. There are two types of hardware expansion connections on the CodeX.
Expansion Headers J1 and J2¶
These 5-pin headers on the top of the board are labeled “Expansion”. They are designed to be compatible with CodeBot expansion boards, like the breadboard expansion
J1 is on the left
J2 is on the right
Pin-1 is the bottom pin of each connector
Peripheral Connectors 0, 1, 2, and 3¶
These 3-pin connectors provide +5V, GND, and a Signal line. They are suitable for directly connecting servos or any other peripheral you’d like to experiment with!
Note that to turn on the +5V power to these connectors you’ll need to use:
power.enable_periph_vcc(True)
See https://docs.firialabs.com/_modules/codex.html#Expansion for details of the IO pins connected to each connector.
