Thin case for TM1638 LED&Key and microcontroller
Description
I still like my previous remix of the TM1638 case, but I've made a version where the base of the case is considerably thinner. This doesn't necessarily accommodate the ElectroCookie PCB or pin headers, but especially if you solder the microcontroller directly to the TM1638 (using solid-core wires), this is a more svelte case. **WARNING** TM1638 boards are not all the same. At the time of this posting, this case fits the TM1638 listing **mentioned above** but didn't fit another listing I ordered. Power comes in from the bottom. I assume you are using a MicroUSB cable to power it. The case uses countersunk [m3 screws](https://www.amazon.com/gp/product/B07CYNKLT2) to affix the lid to the case, instead of glue or tape. Lid and Base to attach using four m3 screws (12mm is about perfect). This design requires m3 heat inserts in the Base. It uses [these m3 heat inserts](https://www.amazon.com/gp/product/B08BJD3W4X).
