HT16K33 0.56" Four Digit Red LED Clock Display Module
$9.95
SKU 94641003
Now available from PMD Way are these convenient assembled LED clock-style displays, with red LEDs. They're 0.56" four digit, seven segment LED displays with a clock colon so you can use them to display time, data or anything else.
The best thing is that they're driven by a HT16K33 LED display controller IC, so you only need the I2C bus from your Arduino or microcontroller, plus power and GND.
Inline headers as shown are included but not soldered to the board.
Display runs from both 5V or 3.3V DC, pinouts are +/-/I2C data "D"/I2C clock "C".
You can change I2C bus address by shorting varierty of pads on rear of PCB. Use I2C scanner code to determine I2C bus, for Arduino, for Raspberry Pi.
