Reviewed in Spain on January 27, 2022
La placa del esp32 es muy completa, pues integra un sistema de carga para baterías de litio ion. Muy bien!!!
Su refigrafia, nombre de los pines, creo que es justa, soldados ya casi no se ve
Pero el hecho de tener 4 estrellas es debido a que le falta una cosa para ser una compra redonda. Que menos que un cablecito de 5 o 10cm con el conector correspondiente para la batería ? Ahora tengo que comprarlo a parte (creo que es el 2.0mm JST PH 2-pin) Sería un detalle que se incluyera.
Por lo demás, es breadboard frindely. Ver la foto. Permite tener una fila de pins libre.
