This battery level display module provides a clear visual indication of power supply status. It features a retro digital tube design with 5 red LED segments representing the charge level, set within a green LED frame for aesthetic contrast.
Controlled by the TM1651 chip, the module uses a simple 2-wire serial interface (data and clock), making it easy to integrate with microcontrollers like Arduino. It operates on a power supply of 3.3 to 5.5 V DC and supports both 3.3 V and 5 V logic levels.
Wiring examples and libraries are available in the documentation.
