Concept
A rechargeable lithium pouch cell. Energy-dense but needs correct charging and protection.
A little theory
Nominal 3.7 V; never charge above 4.2 V/cell. Use TP4056 with protection or a dedicated balance charger. Boost (MT3608) to make 5 V. In the classroom, treat 3.7 V LiPo Pouch 1000 mAh + JST-PH as a intermediate part using JST-PH 2-pin. Typical India street price is about ₹150–₹350. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
How it works in a project
JST to TP4056 OUT or protected pack → boost/regulator → MCU. Never leave charging unattended in class.
Classroom & project use
- Wearable badges
- Small robots
