Here is a simple and a low cost Lithium Battery charging breakout board. This article is about the charger breakout board based on TP4056.

It uses a Micro USB for connecting the breakout board to any computer or 'USB wall adapter'. It works with linear charging method. It offers 1000mA charge current by default but it is adjustable from 50mA to 1000mA by soldering a resistor. The default resistor soldered in on the board is 1.2K Ohm. A resistance and current table has been shown below on this page.

Look at the image below to know the functions of different components on the breakout board:

It is recommended that when you charge a battery, the current(in mA) offered by the breakout board is 37-40% of the battery capacity(in mAh). For example, if you are charging a battery of 1000mAh capacity, you should adjust the resistance in a way that the current offered is approximately 370mA-400mA.

 

Other details:

  • Item Name: 5V Mini USB 1A Lithium Battery Charging Board
  • Charge module: Linear charging
  • Current: 1A adjustable
  • Charge precision: 1.5%
  • Input voltage: 4.5V-5.5V
  • Work temperature: -10℃ to +85℃
  • Inverse polarity: No
  • LED indicator: Red is charging,and GREEN is full charged
  • Input interface: Micro USB
  • Size: 25X19X5mm.

 

Points to be remembered:

  • Ampere meter can only be connected to 5V input end of the module.
  • It is recommended that the charging current is 37% of the battery capacity. If you charge the battery of 1000mAH, current of 400 is enough.
  • The connection wire should not be too thick.
  • No reverse polarity.

 

Use the following table of resistance and current values to solder the right resistor to obtain the required current:

RPROG (k) IBAT(mA)
