I ordered some pro minis, but they supplied the old pattern minis. After popping 2 of them before I realised the pinout is different I've now got 3 left. Too much hassle to get a refund, and too much pointless learning curve to use them, so does anyone want them for free. Just pm me your dirt mail address.

Hi, Duncan

Are you sure you have the 'wrong' boards. The following was copied from the official Arduino site: – note the last two lines – you may have the wrong voltage. Elsewhere I found a comment that the Arduino Mini has been 'retired'

The Arduino Pro Mini is a microcontroller board based on the ATmega328.
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. A six pin header can be connected to an FTDI cable or Sparkfun breakout board to provide USB power and communication to the board.
The Arduino Pro Mini is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires.

The pin layout is compatible with the Arduino Mini.
There are two version of the Pro Mini. One runs at 3.3V and 8 MHz, the other at 5V and 16 MHz.

Regards

I'm absolutely convinced. The layout of the programming pins on the end is reversed, and there is an obvious crystal on the mini, absent from the pro-mini. 3.3 and 5 v pro-mini are physically identical
