You will damage the HC1 when you connect a 3.3v adapter to the UART connector. The Odroid UART-USB adapter is able to switch between both voltage levels automatically, so you can use it with any Odroid board. The Odroid C1 and C2 (and the N1) are using 3.3v levels. For these devices you can use a regular 3.3v adapter and connect it with breadboard cables with the UART pins on the board. -------------- next part -------------- A non-text attachment was scrubbed...
