This is the board layout for a circuit containing two 8x8 LED matrices controlled by some MAX7219 drivers and an ESP8266 microcontroller. It is also possible to cascade multiple boards to get a wider display.
- ESP2866 development board
- 2x MAX27XX LED drivers
- 2x 8x8 single color 60.2mm LED matrices with row cathodes and column anodes
- 2x 10kOhm resistors
- 1x 200nF ceramic capacitor
- 1x 4.4uF electrolytic capacitor
- a power jack
- some sockets and headers
