MAX6953 LED Matrix or development board
The MAX6953 from Dallas Maxim is a compact cathode-row display driver that interfaces a microprocessor (like PIC or AVR) to four 5×7 dot matrix LED display trough an I2C compatible serial interface. The Max chip includes some nice features like:
- low-power shutdown mode
- segment blinking
- test mode that forces all LEDs on
- 16-Step digital brightness control
This project can be considered both a led matrix controller and a development board for MAX6953. The project presents only the max6953 and the led matrix, if you want it to display anything, you’ll also need to stick a microcontroller in there and write some code. You might want to check this other article 50×7 LED Matrix which has everything included.

Hey, i want to make something very similar but can’t find anywhere that sells the MAX6953. Where did you get yours? I’ve tried asking Maxim for samples but their distributor in Australia knocked me back

I can’t seem to find it either, so they must of retired the product.

Maxim still have these chips as active. I recently ordered some for a 4-digit Shield from Maxim direct. They are quite expensive even in quantities.
