Funduino Pro Mini

Funduino Pro Mini

The Funduino Pro Mini is a copy of the Arduino Pro Mini. It is generally less expensive, but is still a reliable board. Since there is no USB converter on-board, a USB to Serial TTL cable of the appropriate voltage will be needed to program it (if you have USB ports). It is pinned out for the same USB to TTL converter as the Arduino Pro - the FTDI FT232R-5V or FT232R-3V3.

The board comes with no headers installed, but in most cases includes the headers. The pinout is typical, with the exception of the analog inputs. A0-A3 are in the normal place, as are A4 & A5. There are A6 & A7 pins on the end opposite the programming pins. Various other pinouts have been seen on boards claiming to be Funduino Pro Mini, but the boards turn out to be other clones.

A size comparison of the four small form factor Arduino boards is helpful to see where the Funduino Pro Mini fits in the tiny Arduino board lineup.

Funduino Pro Mini Pinout

The Funduino Pro Mini follows the standard Arduino Pro Mini pinout, but has a unique location for the A6 and A7 pins. They are located on the end opposite the programming header - next to the reset switch. There is a ground pad with them.
