The TP4056 module is suitable for charging smaller lithium batteries (e.g. from mobile devices, drones) and can be supplied with power via the USB port.
Overview:
- Charging method: linear charging
- Charging current: 100 - 1000 mA, adjustable
- Charging accuracy: 1.5 %
- Input voltage: 4.5 V - 5.5 V
- Full charging voltage: 4.2 V
- Charging indicator: blue light (red light illuminates when fully charged)
- Charging input interface: Micro-USB
- Operating temperature: -10 degrees to +85 degrees
- Weight: 1.8 g
- Dimensions: 23.3 x 17.3 x 3.4 mm
Note: Observe the correct polarity! A reversed connection of the input has no effect on the chip, but a reversed connection of the output (battery end) will short-circuit the chip!
For experienced users: The maximum charging current is 1 ampere as standard. This can be changed by changing the 1k2 (122) resistor next to the "IN-" pad. The following table illustrates the resistance and charging current:
| Resistance | max. current (mA) |
| 30KOhm | 50 |
| 20KOhm | 70 |
| 10KOhm | 130 |
| 5KOhm | 250 |
| 4KOhm | 300 |
| 3KOhm | 400 |
| 2KOhm | 580 |
| 1.66KOhm | 690 |
| 1.5KOhm | 780 |
| 1.33KOhm | 900 |
| 1.2KOhm | 1000 |
