Product description
Large 4-digit 7-segment LED display with red digits and I²C control via Qwiic. The display has 30.5 mm high digits and is supplied with a fully assembled and tested driver board. The driver board handles multiplexing and features constant-current drive and 16-step brightness control.
Communication is via I²C. The address can be selected with jumpers between 0x70 and 0x77, allowing up to eight 7-segment displays to be connected to the same I²C bus. The current version features level shifting and a boost converter and can be used with either 3.3 V or 5 V for both supply voltage and data signals.
The display must be soldered to the driver board before use.
