SparkFun Blocks for Intel® Edison - UART Block
UART Header - Standard FTDI header with RX, TX, VCC, and GND broken out.
Select Switch - Select between Console (UART2) and UART1
Power Button - The power switch is connected to the "PWRBTN" line on the Edison. This give 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.
LED Jumper - If power consumption is an issue, cut each jumper to disable LED
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.
