Getting Started with CB030, Rev0

This guide assume you already have a fully assembled CB030 rev0 as shown in the picture above.

The console serial port is the 6-pin connector labelled 'P6'. The pin assignment is for direct connection to a CP2102 USB-serial adapter as shown in the picture below. Set the terminal emulator to 38400 N-8-1

CB030 requires regulated 5V, 1amp. The power plug is 2.5mm X 5.5mm which is not compatible with the more popular 2.1mm X 5.5mm connector.

Apply power to CB030 and the following message will display after about 1 second delay:
