SparkFun Blocks for Intel® Edison - Base Block
CaseyTheRobot 
Board Overview
USB OTG - The USB Micro AB port provides access to the Edison OTG port. This port is capable of providing power to an OTG device or power can be supplied to the Edison through this port.
Console - The Micro USB B port provides power and a console access port to an Intel Edison Stack. This Block supplies a voltage to the Edison and other Blocks through the VSYS line at 4V. This voltage may vary up to +/-0.1V depending on load.
Power Button - The power switch is connected to the "PWRBTN" line on the Edison. This gives the user the ability to place an Edison in sleep or power down the module completely. This does not affect power to other Blocks in the stack.
Power LED - The power LED illuminates when power is present on VSYS. This can come from the Console Block, or any other powered Block in the stack.
Data LEDs - The Data LEDs help the user identify if the console is active. This is a feature commonly found on our FTDI breakout.
LED Jumpers - If power consumption is an issue, cut each jumper to disable LEDs
Expansion Header - The 70-pin Expansion header breaks out the functionality of the Intel Edison. This header also passes signals and power throughout the stack. These function much like an Arduino Shield.
