The TP4056 Type-B Charging Module is based on the TP4056 lithium battery charging IC and is used for safely charging single-cell 3.7V Li-ion/Li-Po batteries such as 18650 Li-ion Battery.
Unlike the Type-C version, this module uses a Micro USB Type-B connector, which is common in older Arduino cables and mobile chargers.
Most versions include:
Overcharge protection
Over-discharge protection
Short-circuit protection
It is widely used in DIY power banks, portable devices, robotics, and battery-powered projects.
