Board Pinout

The pinout diagrams below show the expansion interface signals. Arduino UNO shields can be used on these connectors by aligning D15 on the shield and LPCXpresso55S69 board. https://os.mbed.com/media/uploads/brendonslade/pinouts_page_1.png https://os.mbed.com/media/uploads/brendonslade/pinouts_page_2.png

Interface Firmware

Prepare the board for usage with Keil Studio Cloud

Before connecting your board to Keil Studio Cloud, you need to flash the latest firmware onto the integrated debug adapter that is connected to the Micro-USB connector P6.

Download the latest LPC-Link2 firmware page and follow the update instructions on the UPdating LPCXpresso firmware page.

Alternatively, you can use a ULINKplus debug adapter and connect it to the 10-pin Arm Cortex connector (P7). This debug adapter is recognized by Keil Studio Cloud and can be used to flash and debug any development board.
