• Female USB breakout

    The first thing I wanted to do was to make sure that I could interface the Trinket Pro with the serial console port of a router. To do this I used a Cisco 1841, an RJ45-to-DB9 adapter, and a DB9 to USB male adapter on the end. To interface with the Atmega328 UART port I had to first break out the USB pins.

    For this I used a knock-off Apple Lightning to USB adapter. I had ordered the adapter for work, but because it was a cheap clone it didn't meet the power requirements of the iPad Air I was using it with. So I cut off the lightning connector to get to the 4 USB wires. I soldered them to a common perfboard and then some male headers to that.

    Next I plan on writing a simple program to basically turn the serial monitor in the Arduino IDE into a terminal for the 1841.
