Case has a close fit, but a knife edge near the corner can be used to open the case. Standard serial header pattern present on the board as shown:

GPIO Pinout

Pin	Function
GPIO00	Reset BUTTON
GPIO01	TX
GPIO03	RX
GPIO04	Red status LED
GPIO12	Door Relay
GPIO13	Green status LED
GPIO14	Door Closed Sensor

Basic Config

Pressing the reset button .5-2 seconds will pulse the door relay. On each transition of the door sensor, the green LED will blink.

Delux Config

This adds sensor checking, so that the closed button does nothing when the door is already closed. Similarly if the door is open, the open button does nothing.
