I was digging around trying to find some information on an obscure LCD module, and came across this interesting table (compiled partially in Russian) that correlates a lot of older mobile phones with their specific LCDs, LCD controllers, dimensions, serial bus, etc. If you’re looking for cheap LCDs of a specific physical size or resolution, this might be a good starting point since there may still be spare parts floating around out there. If nothing else, it’s just an interesting read looking at how much time and effort went into this thing (presumably a repair shop owner, or something similar).

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
