While it may look like a simple knob, the HW-044 is a rotary encoder module favored by Arduino and ESP32 enthusiasts for its reliability and ease of use. In this post, we will break down the "datasheet" specifications, explain how it works, pinout configurations, and provide a wiring guide to get you started.
The HW-044 module operates as a constant-current/constant-voltage (CC/CV) linear charger. Below are the key electrical and physical parameters: 4.5V to 5.5V DC Full Charge Voltage: 4.2V DC (accuracy within ±1%) hw-044 datasheet
