 32 kbit I2C E2PROM for storing non-volatile parameters
 Powered via Android device’s normal USB power plug
 +5V DC external supply can also be connected via standard 2.1mm power jack
 SWD/JTAG connector
 2x5 pos, 50 mil/1.27 mm pitch, standard SWD/JTAG connector
 Small prototyping area
 100 mil pitch matrix of holes, 64 x 23 mm in size
 Compact size of complete board: 135 x 100 mm (5.4 x 3.9 inch)
 Four layer PCB design for best noise immunity
2.1.2 LPC11C24 side features
 NXP's LPC11C24 ARM Cortex-M0 microcontroller in 48-pin LQFP package, with 8 KByte
internal SRAM, 32 KByte internal FLASH and integrated CAN transceiver.
 12.0000 MHz crystal for maximum execution speed and standard serial bit rates, including
CAN requirements. The LPC11C24 runs at frequencies up to 50 MHz.
 Can be broken off from LPC1769 side of the board to create a remote CAN node.
 DSUB9 and RJ45 CAN interface
 Pads exist but connectors not mounted (only needed to expand CAN network or when
LPC11C24 CAN node broken off from LPC1769 side).
 RGB-LED
 LED on PIO0_7 (compatible with LPCXpresso LPC11C24 board design)
 Push-button
 On wakeup pin (PIO1_4), allowing low-power experiments
 LM75 temperature sensor on I
2
C
 ISL29003 light sensor on I

C
 Powered via CAN interface
 +5V supplied, local 3.3V regulator on board
 All relevant LPC11C24 pins available on expansion connectors (dual 20 pos edge connector,
100 mil/2.54 mm pitch rows, 700 mil apart).
 SWD/JTAG connector
 2x5 pos, 50 mil/1.27 mm pitch, standard SWD/JTAG connector
 Compact size of LPC11C24 node: 69 x 23 mm (complete board is 135 x 100 mm)
2.2 ESD Precaution
Please note that the AOAA Board comes without any case/box and all
components are exposed for finger touches – and therefore extra attention must
be paid to ESD (electrostatic discharge) precaution.
