HT16K33

Quick Decision Notes

HT16K33 is indexed as a displays part from Holtek. ChipScout tracks it by practical maker-facing dimensions: interfaces, library readiness, estimated price, field-level sources, and whether the page is strong enough for selection rather than only lookup.

Pinout Table

Pinout is not yet source-verified. Use the table as an integration checklist, then confirm exact pins against the module vendor page before wiring hardware.

Common Wiring

Arduino Example

#include <Wire.h>

void setup() {
  Serial.begin(115200);
  Wire.begin();
  Serial.println("HT16K33 I2C wiring smoke test");
}

void loop() {
  // Replace this with the maintained HT16K33 library call.
  Serial.println("Check HT16K33 on the I2C bus, then read a sample.");
  delay(1000);
}

MicroPython Example

MicroPython support is pending. Treat community scripts as prototypes until a maintained driver is linked and tested on a known development board.
