Two dry cell batteries cannot provide a stable voltage for a long time. The voltage range of two dry cell batteries is 1.8V-3V, or a maximum of about 3.2V.PW5100 can be used for boosting and stabilizi
Battery life is one of the most important factors to consider for IoT devices. It’s easy to understand why. Consumers generally expect their applications and devices to have longer battery life. For e
1. Start testing after getting the module. I downloaded an Arduino development kit from the official website. Because I haven't tested the Arduino development board recently, even the software is down
