This is a small Arduino pro mini 328 3.3v 8mhz that runs the bootloader. Arduino Pro Mini does not have connectors that are populated, which allows you to connect any wire or connector in any orientation you require. We suggest that first-time Arduino users to start on Uno R3. Uno R3.
It’s a fantastic board that can get on the right track quickly. Arduino Pro is a great board that will get you up and running quickly. Arduino Pro series is meant to be used by those who are aware of the limitations of the system voltage (3.3V) as well as the absence of connectors, as well as USB off-board.
Arduino pro mini 328 3.3v 8mhz board is connected directly with the FTDI Basic Breakout Board and has auto-reset capabilities. This board is similar to the Arduino Pro Mini also works with the FTDI cable, however, the FTDI cable is not able to allow access to the DTR pin, so the auto-reset feature won’t perform.
The voltage regulator is on the board, which will accept voltages as high as 12 VDC. If you’re connecting non-regulated electricity to your board ensure that you connect directly to RAW and not VCC.
The most recent and best model of the board cuts off both the ADC6 as well as the ADC7 pins and includes footprints for the optional I2C pulled-up resistors!
