The measuring circuit is completely isolated (with optocouplers and DC-DC 5v Isolated) from the other circuits: processor, USB, charging. Does not charge from the communication USB-B. It has 2 18650 batteries (Much autonomy) Indicates the level of charge on the screen. It does not indicate whether it is charging or powered from the outside, although it has a red light behind. The display looks spectacular: viewing angles, backlight and contrast (black good) I do not think about its operation because there are already reviews on the internet that give a lot of information.

El circuito de medida esta completamente aislado (con optoacopladores y DC-DC 5v Isolated) del resto de circuitos: procesador, USB, Carga. No carga desde el USB-B de comunicacion. Tiene 2 baterias 18650 (Mucha autonomia) Indica nivel de carga en pantalla. No indica si esta cargando o esta alimentado desde fuera, aunque tiene un piloto rojo por detras. La pantalla se ve espectacular: angulos de vision, retroiluminacion y contraste (negro buenisimo) No opino sobre su funcionamiento por que ya hay reviews en internet que dan mucha informacion.
