Description: 1. Function: Solar Power Manager (SPM) is a versatile microcontroller-based charging controller designed for 5V solar applications. It efficiently manages charging processes of LiPo, NiMH, and lead-acid batteries from various renewable energy sources like solar panels. 2. Features: SPM comes with an adjustable charge voltage up to 6.6V, current limiting (up to 4A), overcharge protection, low voltage cutoff, and reverse polarity protection for battery safety. It also includes an integrated voltage regulator that outputs a stable 5V DC for powering loads. 3. Benefits: Compact size (57mm x 32mm), easy-to-use design, and wide compatibility with various battery types make Solar Power Manager an ideal choice for portable projects such as solar charging systems, DIY electronic devices, and remote sensing applications. 4. User interface: SPM offers a simple yet effective user interface through LED indicators showing charging status (Charging, Full, Fault) and a single button to reset the c
