The AZDelivery 4-digit display is your bright choice for quick and energy-saving display of counters, time or a high scores for home-made mini-games.
The control works without problems via one of the numerous open source libraries available on the Internet. Not only can each character be controlled separately, but also each individual segment as a LOW level. Furthermore, the brightness of the module is adjustable in 8 levels.
Thanks to the software-emulated I²C interface, the display can be addressed via any GPIO port. Only two additional data pins per display are required in addition to the shared 5V and GND connections. The whole board is, not counting the protruding pins, 41.5mm long, 23.5mm wide and 11mm high. The individual 7-segment characters measure 5x9.5mm. For the LED module itself, a 20x14mm rectangle must be cut out for rear panel mounting. Four mounting holes are already provided for fixing, suitable for M2 screws.
