Firmware (HEX) file and documents for the Micromite Mk.2 and Micromite Plus
Firmware, user manuals, change log and sample C functions for the Micromite Mk.2 and Micromite Plus (v5.05.03).
The regular Micromite HEX file will work on the 28-pin DIP package chip (PIC32MX170F256B) and the 44-pin SMD chip (PIC32MX170F256D).
It's also suitable for the MicroMite LCD BackPack including V2 and V3. See the articles in the January 2015, February 2016 and August 2019 issues for more details.
The Micromite Plus HEX file will work on the 64-pin and 100-pin TQFP package chips (PIC32MX470F512H/L).

Matte/Gloss Black UB3 Lid for 2.8-inch Micromite LCD BackPack
A lid laser cut from 3mm black acrylic which replaces the lid supplied with a UB3 "Jiffy" box. Attaches with the supplied screws. One side is gloss black, the other side is matte black. You can fit it either way around.
The 2.8-inch Micromite LCD BackPack is mounted on the rear of the lid using four M3 machine screws, with the touch-screen flush with the top surface. The cut-out is sized to leave minimal clearance around the screen. The cut-out and mounting holes are positioned so that the viewable area of the TFT display is centred. This lid can also be used with the Micromite Plus LCD BackPack.
130.5 x 68.2mm.
Note: for the lid to fit, the LCD pin header solder joints (top side) must be trimmed. Use two M3 washers (or one 1mm thick Nylon washer) as spacers between the TFT PCB and the lid.
