39c3PCBLEDC100R
39c3PCBLEDC100R is an open source PCB design by c3re: a 2-layer, 100 × 100 mm board with 14 components (6 distinct parts).
The 39c3PCBLEDC100 is a Coaster for your drinks with option for LED and microcontroller upgrade. By stacking the coasters, you can also build nice blinky towers.

Important: Do not power the board by USB and an external power supply at the same time! The Din pin of the first LED is connected to pin D4 (GPIO2) of the Wemos D1 mini. ...well, not directly: there is a MOS-FET Transistor in between to shift the signal level from 3.3V to 5V. Two of the mounting holes are connected to GND, two of the holes are connected to 5V. You can use this feature to stack multiple 39c3PCBLEDc100R Boards with…
