TP4056 Li-ion Battery Charger Module (with circuit protect, 1A, 4.2V)




The TP4056 charger module is a single-cell Li-Ion battery charger board with a constant current/constant voltage linear charge output. The board has a micro USB and input pin so it’s suitable for USB and power adapter supplies source. This board has a built-in protection circuit for over voltage and over current to prevent the batteries from damaging.  This board can accept 5V input, if the input voltage is too high, like 5.2V, the current will be less than 1000 mA where it is normal.

Other features of the TP4056 include battery temperature sensing, under voltage lockout, automatic recharge. This board also has two LED status pins for charging (red) and for complete charging (blue).
