This Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Arduino Pro Mini also works with the FTDI cable, without the auto-reset. There is a voltage regulator on board so it can accept voltage up to 12VDC. If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin, not the VCC.
