Abrazadera de empalme - Abrazadera de conexión - Panel de extensión de terminal rojo, medios interactivos, compatible con el módulo Uno R3

We are still experiencing a poor connection at the port. Both the use of inline breadboards and the use of the sensor cable expansion card with DuPont are less reliable.

It also increases the number of pins to facilitate connection to digital or analog sensors.
