- Case for a MAX 7219 display, controlled by a ESP 8266 (or ESP 32). Standard plugable USB-connection for power input. Simple wiring via jumper-cables. - Used for displaying data (such as time, weather etc.). - Designed for mounting below a shelf board (114 mm spacing between the mountings (3, 4)). - Front side is slightly tilted (for optimal view when sitting on a couch and display is mounted in the livingroom cabinet :-)). - No supports required (print case and adapter IR frontside facing down). - Lock into position MAX 7219 (9) and the four fixings (5, 8) as well as the magnets (1, 7) with some two-component adhesive. - Adequate software is available in a huge amount in the net.
NOTE: Solder an additional electrolytic capacitor between the plus and minus contacts of the MAX 7219 (see picture) for enhanced voltage stability.
