Firmware (HEX) file and BASIC source code for the Micromite-based Touch-screen Boat Computer with GPS [V7]
Revised firmware (both with and without pre-loaded BASIC code) and BASIC source for the GPS Boat Computer.
Includes Micromite firmware.
Version 7 improvements: Added altitude readout as described in Circuit Notebook, August 2020.
Version 6 improvements: Changed the 'speed' variable to a float to improve Km/h accuracy.
Version 5 improvements: Fixed a small issue related to drawing the blue border which only affects Micromites running MMBasic V5.2. Note that BoatComputerFullV5.hex uses MMBasic V5.1.
Version 4 improvements: Fixed an issue that prevented selecting the SET button for some POIs.
Version 3 improvements: Fixed a bug which could cause the software to repeatedly crash and restart when creating a POI at lat/lon 0,0 (or another distant location).
Version 2 improvements: You can now have over fifty Points of Interest. The heading indicator and POI direction indicator are now suppressed when the boat is stationary. Improved the rendering of the heading needle. Removed the slash from the numeric zero character in one of the fonts. See changelog in ZIP file for more details.
For the Micromite user manual, see the separate shop item.

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.

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.
