The RPi LED array is a printed circuit board that mates directly with the GPIO (general purpose input/output) headers of a Raspberry Pi computer. This module adds a 10 LED array that can be controlled ...

This board uses two 10 LED bargraphs to make up the display. 20 LED arrays are available but are not suitable for this design. This board layout has two links. Again R3 is fitted in the lower of ...

Circuit Diagram: The circuit Diagram this Bluetooth controlled LED board built using the EasyEDA application. We will use the same schematics to develop a PCB from it and fabricate it using EasyEDA..

In this paper, we report the design and fabrication of fine-pitch and pixelated-addressed micro-light emitting diode (LED) arrays with emission wavelengths of red (R), green (G), blue (B), and ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some… ...

Single LED array version Note the two links on the circuit board and that R3 is fitted in it's "alternate" position. Component layout - top view (left) and Track layout - Viewed from above (right) ...
