LPC812breakout

Breakout Board for the NXP LPC812M101JPH20 microcontroller. Includes push buttons for reset and activating the serial bootloader. The board has an integrated 500mA 3.3V LDO to supply both the MCU and connected devices from the USB port.

The four pins on the top side (5V,RX,TX,GND) can be used to connect a cheap USB to serial adapter (<$2 on ebay) and program the device via the internal bootloader using FlashMagic. Note that you have to cross RX and TX. RX from the serial port goes to TX and vice versa for TX.

• FlashMagic can be downloaded here.
• Developer environemt and LPC800 datasheets by NXP can be found here.

The entire board with LPC812 is smaller than a DIP LPC1114. See below for size comparison.

Bonus: Eagle Library for all LPC800 parts

You can order PCB's here: Shared design at OSH Park The price is $3.30 including shipping for three boards.
