TP4056 Li-ion चार्जर मॉड्यूल पिनआउट

पिन

IN+ / IN− (5V in — or just the USB connector)
B+ / B− (the single Li-ion cell, 4.2V charge termination)
OUT+ / OUT− (protected output — only on boards with the DW01 + FS8205 protection pair)
Red LED = charging, blue/green LED = done
Charge current is 1A by default (Rprog 1.2kΩ) — swap Rprog to lower it for small cells
Basic boards have no load-sharing: power the load from OUT and expect charge termination to misbehave if the load draws during charging

Charger IC	TP4056 (linear, constant current / constant voltage)
Input voltage	5 V nominal (4–8 V per the datasheet)
Charge voltage	4.2 V ±1%
चार्ज करंट	Up to 1 A, I = 1200 / Rprog (1.2 kΩ = 1 A on most modules)
Trickle charge	1/10 of set current below 2.9 V
Charge termination	When current falls to 1/10 of the set value
Recharge threshold	≈ 4.05 V
Battery	Single Li-ion / Li-Po cell (1S) only
Protection (DW01A boards)	Over-charge ≈ 4.3 V, over-discharge ≈ 2.4 V, over-current and short-circuit cut-off
Status LEDs	Red = charging, blue/green = done
