"Power Inputs"


"Power Management"


"Voltage Regulation"


"Protection and Indicators"


"Regulated Outputs"


























"Solar Panel (6V, node_2W)"
"USB Power (5V)"
"Li-ion Battery (3.7V, node_2000mAh)"
"Battery Charger (MCP73831)"
Power Selection Circuit
"Boost Converter (MT3608)"
"Buck Converter (AP7333-33)"
"Buck Converter (AP7333-18)"
Schottky Diodes & Capacitors
LED Indicators
5V Output
3.3V Output
1.8V Output
This diagram shows:
  • The inputs from the solar panel, USB, and battery feeding into the battery charger, which then charges the battery.
  • The power selection circuit automatically switching between power sources.
  • The voltage regulation paths where the battery voltage is boosted to 5V or bucked down to 3.3V and 1.8V.
  • The protection components along with LED indicators for status monitoring.
  • The final regulated outputs (5V, 3.3V, and 1.8V).
Feel free to adjust or ask if you need further modifications!
