Other key parts include the TLC5971PWPR. By type, the board carries 16 diodes, 5 capacitors, 4 ICs, 4 resistors and 3 connectors.

It belongs with the displays & leds designs in this gallery.

From the project

LEDBoard with 4x4 Nichia SMD-LEDs with controller for individual 16bit-channel control

a LED-Matrix Board that can be combined seamlessly to bigger areas. It uses the TI TLC5971 Constant-Current LED-Driver Chip with 16bit dimming resolution.

The original LED-footprint was for Nichia NSSM032A RGB-LED. Back in 2017 on of the brightest low power SMD LEDs in this size - They are only available as full reel directly from Nichia.

so there is a second branch with the LED-Type changed to Nichia NSSM124D - these are available as cut-tape from an distributor.
