This board is a clone of the Arduino Mini Revision 5. While generally more affordable, it remains a reliable option for embedded projects. Since it does not include an onboard USB-to-serial converter, programming requires a USB-to-Serial TTL adapter (such as the FTDI FT232R-5V or FT232R-3V3).

The board is typically shipped without pre-soldered headers, though headers are often included separately. Its pinout is mostly standard: A0–A3 are in the usual positions, while A4 and A5 remain I²C-compatible. Additionally, it provides A6 and A7 analog pins located on the opposite side from the programming header. Note that some clones with varying pinouts are marketed as “Funduino Pro Mini,” but may differ from this layout.

Arduino Mini (revision 05) has a new package for the ATmega328, which enables all components to be on the top of the board. It also has an onboard reset button. The new version has the same pin configuration as revision 04.
Warning: Don't power the Arduino mini with more than 9 volts, or plug the power in backwards: you'll probably kill it. Headrers are not soldered in our current stock.
