Firmware (HEX) file and user manual for the Micromite
Firmware and PDF user manual for the 28-pin Micromite device.
Load the firmware onto a PIC32MX150F128B-50I/SP or similar (see articles).
Please note: this is a revised version compared to the one originall posted (now V4.5C) which fixes a rare bug which can cause the Micromite to become "bricked". We recommend users upgrade to this version if possible.

CP2102-based USB/TTL serial converter with 5-pin header and 30cm jumper cable
A small USB/serial converter module which plugs straight into a USB port and provides a standard 5-pin header interface with 5V, 3.3V, GND and TTL (3.3V) serial TX/RX pins. Suitable for direct connection to any of the Maximite or Micromite projects.
Modern operating systems like Windows 10 should not require any drivers to use this device - plug it in and it should be recognised and ready to use straight away.
The 5-way cable supplied has female "Dupont" headers on both ends, which plug into standard pin headers. It can be used to connect the adaptor to a Micromite LCD BackPack.
We have only tested this adaptor in Windows; it should work with Linux and Mac OSX.

PIC32MX170F256B-50I/SP programmed for the Micromite Mk2 plus capacitor
A 32-bit PIC microcontroller in 28-pin DIP programmed as the Micromite Mk2. Also includes a through-hole Tantalum capacitor to use for its internal regulator - with sufficient capacitance and voltage rating for the job, adn batch tested to have suitably low ESR.
Chips are now programmed with the revised v5.05.03 software (or higher). Note that the capacitor supplied may be a Kemet Solid Molded Tantalum type, in which case the positive lead is indicated by the rounded edge on the case and a dot marking on the top.
