Grove - 4-Digit Display
Seeed Studio · 2055
2055Grove - 4-Digit Display module is een 12-pins module. In deze module wordt een TM1637 chip gebruikt om het aantal besturingspinnen terug te brengen tot 2. Dat wil zeggen, hij bestuurt zowel de inhoud als de luminantie via slechts 2 digitale pinnen van Arduino of Seeeduino.
