After a fresh CircuitPython install on a new controller, you’ll still need to add the support framework for TerrainTronics boards. The “lib” directory on your CIRCUITPY drive should be empty.

Install external CircuitPython content

• download https://gitlab.com/lumensalis/demodata/-/raw/main/CircuitPyDependencies.zip 
• unzip contents into your CIRCUITPY drive
• you should now have a bunch of adafruit files and directories in CIRCUITPY:\lib, and a font5x8.bin file in the root directory

Install TerrainTronics modules

• download https://gitlab.com/lumensalis/terraintronicscp/-/archive/main/terraintronicscp-main.zip?path=CircuitPyPartialImage 
• open terraintronicscp-main-CircuitPyPartialImage.zip and go to terraintronicscp-main-CircuitPyPartialImage/CircuitPyPartialImage/lib. You should see a directory called TerrainTronics. Copy (drag & drop) this directory into CIRCUITPY:\lib
