Datasheet

Max Voltage Input: 16VDC
Max Current Output: 150mA
Remember, RXI is an input pin into OpenLog.
This board is meant to couple directly to Arduino Pro and Pro Mini.
This board cannot be directly connected to an FTDI Basic.
To connect OpenLog to an FTDI basic, you will need to swap
TX and RX lines between boards.
