El m\u00f3dulo de desarrollo Heltec Wireless Stick Lite tiene el circuito de sensor y alimentaci\u00f3n por bater\u00edas. El diagrama de pines muestra que el pin 13 se encuentra conectado como detector de energ\u00eda, que se incorpora a las instrucciones como PowerDetection. En los nuevos modelos, el detector de energ\u00eda es el pin 37.<\/p>\n

Preparaci\u00f3n de trama<\/h2>\n

El valor del sensor ADC para bateria es de tipo entero, entrega la cuantificaci\u00f3n en el rango [0, 4096], por lo que un entero de 2 bytes es suficiente para los datos. El proceso de conversi\u00f3n a voltaje se realiza en el decodificador en Application-Server del Broker ChirpStack.<\/p>\n
