Description
Overview
Amuse Tech Solutions LoRa Wi-Fi module is crucial and must connect to the IPEX interface to prevent potential damage to the LoRa chip. The device includes a lithium battery charge and discharge circuit with a status indicator LED that stops when the battery is fully charged. When using the IO port for touch screen signal input, it’s essential to add a 100 nF pull-down capacitor to ensure stable signal reception.
