This Pro Mini Breakout Board is a great low power alternative to a 5V Pro Mini in your projects. Just solder on the header & programming pins and pop onto a breadboard or solder directly into your projects to save space! Power using a 3.3V-12V power supply and that's it! Wire into your circuit using the pin diagram in the images above and plug into your computer's USB port using the FTDI Cable to program! This version is the 3.3V version which makes it consume less power as well as easier to integrate with other 3.3V devices such as GPS modules, Raspberry Pi, MSP430, etc. The main difference between the Pro Mini and Pro Micro is that the Pro Mini has header pins that require a separate FTDI USB Serial Adapter for programming while the Pro Micro has an onboard microUSB port. We recommend the Pro Micro with onboard USB if you're working on a single project and don't already have the FTDI USB Serial Cable.
