GITHUB REPO: https://github.com/sparkfun/SparkFun_MicroMod_Main_Board_Double
DEVELOPMENT ENVIRONMENT SPECIFICS:
Firmware developed using Arduino IDE v1.8.12
========== DESCRIPTION==========
This example code toggles the Function Board's AP2112 3.3V voltage
regulator's enable pin. The Function Boards built-in power LED should blink.
This example is based on Arduino's built-in Blink Example:
https://www.arduino.cc/en/Tutorial/BuiltInExamples/Blink
Note that this example code uses the MicroMod Main Board - Double. The MicroMod
Main Board - Single routes the PWR_EN0 pin slightly different for the
function board.
========== HARDWARE CONNECTIONS ==========
MicroMod Artemis Processor Board => MicroMod Main Board - Double => Function Boards

/*Define the power enable pins for the processor board with SDIO_DATA2.
Depending on the processor board, the Arduino pin may be different.
Note: Certain Processor Boards like the Artemis have more than one pin available
to control the Function Board's voltage regulator (e.g. SDIO_DATA2 and G5).
SAMD51, ESP32, and STM32 Processor Board pins do not have SDIO Data 2, so
users will need to reference the Processor Pin G5. Below are a few examples. */
