====== Hardware Design Requirements ======

Hardware design requirements are for general requirements that help improve the ability to test, debug and program the hardware device.

**Platforms must**:

  * Provide an in circuit programming interface
  * Provide self-programming support through a UART interface
  * The UART interface must be compatiable with the FTDI breakout boards supplied by adafruit and sparkfun
  * Be able to be powered and operational without a battery - meaning the board must provide an external interface to be able to power the board.
  * Platforms with an XBee transceiver must provide a LED linked to the RSSI pin
  * Provide a functional block diagram outlining functional modules down to the MCU level.
  * Provide a circuit diagram
  * Provide an equivalent circuit model(s) for all components
