Cátodo Común en Displays

0:08

Es cátodo común.

En el contexto del proyecto aparece explícitamente como “Common cathode” en la descripción del display TDCG1060M, junto con “10 mm digit height displayed in green”

Si quieres, también te puedo decir qué pines son los cátodos comunes y cuáles corresponden a cada segmento según el datasheet.

PERO EN QUE PIN SE ALIMENTA?

En un display de cátodo común, no se “alimenta” por un solo pin positivo fijo.

Los pines comunes van a GND.
Cada segmento se enciende aplicando voltaje positivo a su pin correspondiente a través de una resistencia.
O sea: el común se conecta a tierra, y “alimentas” cada segmento individualmente.

Entonces, en tu caso:

Cátodo común = a tierra
Ánodos de segmentos = señal positiva para encenderlos

Si quieres, te saco el pinout exacto y te digo:

qué pines son COM
qué pin es a, b, c, d, e, f, g, DP

Eso sí, para decirte el número de pin exacto necesito leer el pinout del datasheet, porque no debo adivinarlo.
