HT1621 6桁 7セグメントLCDモジュール

The six digits are nice and large, so I can read readings from across my bench without squinting. Hooked it up to an HT1621 driver and it fired right up with the green backlight making everything crisp.

That green backlight really makes the digits pop, even in a bright room. I've got it wired up as a simple counter and the large characters are a huge plus for readability from across the desk.

The 6-digit display is surprisingly easy to read from across the room, and the black-on-green contrast is perfect for my workbench. I've had it up for a week now and the built-in communication interface made setup really straightforward.
