UART Block Functional Diagram

• 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.

Using the UART Block

To use the UART Block, attach an Intel Edison to the back of the board or

add it to your current stack. Blocks can be stacked without hardware, but it

leaves the expansion connectors unprotected from mechanical stress.

UART Block Installed

We have a nice Hardware Pack available that gives enough hardware to

secure three blocks and an Edison.
