Olimex DuinoMite-Mini Maximite-Compatible Basic Computer

The Olimex DuinoMite-Mini is a Maximite-compatible Basic computer, originally designed by Geoff Graham, with additional features.

The DuinoMite allows you to program in BASIC language and includes a VGA and PS/2 keyboard interface, so you can develop and write your code in Basic without the need for any other computers.

You can store your code on a Micro-SD card and execute it on power-up through autoexec.bas main code.

Warning

Do not use the ‘programmer-to-go’ button when there is no image on the OLIMEX PIC-KIT3 or MICROCHIP PIC-KIT3 because that might put your microcontroller in an irrecoverable state. We have tested the mentioned scenario and we can confirm it destroys PIC32 chips (using both our and the original Microchip PICKIT3). We cannot take responsibility if you break your chip this way.
