The HT1632 is a multiplexing LED driver that can control up to 384 LEDs at once. If you’d like to use the HT1632 in a project, this pre-built board complete with four 64-LED dot matrix displays can be used to start testing your code while you design the rest of your project. An easy way to get started would be to use the Adafruit HT1632 Arduino library; Adafruit_HT1632.h. Note that while the HT1632 can control up to 384 LEDs, this module only features 256 LEDs.

The module features a 6-pin JST-XH 2.54 mm connector for which an optional wire connector may be included at extra cost. The cable may be supplied with bare ends or terminated with female DuPont connectors.

The 52-pin TM1681 seems to be a pin-compatible drop-in replacement for the HT1632 but I haven’t yet tested that myself.

The pound coin shown in one of the photographs is intended to give a sense of scale and is not included in the sale.
