Varianta cu pini
 

Acest produs este disponibil atat in varianta fara pini (ca in pozele de mai sus), cat si in varianta cu pini tata gata lipiti, ca in imaginea de mai jos. Daca doriti varianta cu pini, selectati optiunea "Da, cu pini lipiti". Acest lucru va adauga 5 RON la pretul produsului. Daca alegeti varianta cu pini, cea mai simpla conectare cu placa Arduino se face folosind un set de fire mama-tata.
