Driverul de afi\u0219are TM1637 comanda \u00een acest caz un afi\u0219aj digital de 4 x 7 segmente LED cu catod comun.
\nFoarte u\u015for de folosit \u00een proiectele tip Arduino.
\nChipul integrat este B-type BCD encoders.
\nModulul este compatibil cu 5V \/ 3,3V la diverse tipuri de microcontrolere.
\nDimensiuni : 71 mm x 22 mm x 12 mm<\/p>\n

 <\/p>\n

Pini :
\nVCC – 5V
\nGND – GND
\nDIO – Pin Arduino
\nCLK – Pin Arduino<\/p>\n

Precautii: Atentie nu inversa\u0163i VCC \u0219i GND , altfel arde\u021bi cipul.
\nDac\u0103 utiliza\u0163i microcontrolere din seria 51 monta\u021bi pe porturile P0 rezistori pull-up.<\/p>\n
