Shown here is a high level block diagram of the board and its main components. The bottom block represents the Xpresso board for LPC54102. The Xpresso board offers on-board debugger, current measurement circuitry and one tri-color LED among other features. The sensor shield board stacks on top of the Xpresso board and contains multiple sensors. These sensors are connected to the LPC54102 MCU via I²C port. The board also contains an infrared LED and receiver for IR remote control applications. The Bluetooth LE module from ACKme is connected via UART.
