Iduino Pro Mini is a clone of the older Arduino Pro Mini. It has only 6 analog inputs, rather than the current Pro Mini's 8 inputs. It is available with either an ATmega168 or an ATmega328. The ATmega168 version is more expensive. The board is only available in a 5V version. We tested the ATmega168 version, since it was unusual to find one these days. The top of the MCU was defaced so it couldn't be read, but the device code is for an ATmega168.

It turned out to be just what we expected. The ATmega168 version compares to the Arduino Pro Mini in every way except memory capacity. Some of our test programs are over 20k, and just won't fit. We ran a few that would fit, and all went well.

The pinout of the Iduino Pro Mini is typical of the Arduino Pro Mini boards, with the exception of the missing A6 and A7 pins.
