 # pico-led-matrix
+
+Tiny modular LED matrix. Idea is to have a matrix of 50x50mm modules:
+
+- LED modules with a 20x20 matrix of 0603 red LEDs.
+- Multiplexer/driver modules at the end of rows and columns
+- Microcontroller (RP2040) board in the corner.
+
+JLCPCB Assembly optimized.
+
+This is an electronics learning experiment, will likely fail. I do not know what I'm doing

+Learning how to use shift registers, darlington arrays, and mosfets. I don't know what I'm doing.
+
+Demo board containing LED Matrix module + some of the above components for hands-on experimentation.
