Power

CN3065

Solar lithium battery charger IC used in small solar sensor nodes.

China-madeConsonanceActiveModerate

Best For

Projects needing Solar charging and Li-ion with a commonly available power part.

Avoid If

You need production-grade certainty without checking the exact module vendor, pinout, and library maintenance status.

Quick Decision Notes

CN3065 is indexed as a power part from Consonance. ChipScout tracks it by practical maker-facing dimensions: interfaces, library readiness, estimated price, field-level sources, and whether the page is strong enough for selection rather than only lookup.

Source Resources

Pinout Table

VCC3.3VPower the module from a rail that matches the breakout board, not just the bare IC.
GNDCommon groundConnect ground between the controller, sensor/module, and external power supply.
SignalMCU GPIO / ADCUse a digital input, output, PWM, or ADC pin based on the module output type.

Pinout is not yet source-verified. Use the table as an integration checklist, then confirm exact pins against the module vendor page before wiring hardware.

Common Wiring

VCC

Power the module from a rail that matches the breakout board, not just the bare IC.

GND

Connect ground between the controller, sensor/module, and external power supply.

Signal

Use a digital input, output, PWM, or ADC pin based on the module output type.

Arduino Example

Arduino support is not verified for this record yet. Add a library resource in the admin panel once a maintained driver or vendor SDK example is confirmed.

MicroPython Example

MicroPython support is pending. Treat community scripts as prototypes until a maintained driver is linked and tested on a known development board.

Recommended Development Boards

ESP32-C3 development board

Low-cost Wi-Fi/BLE board with enough interfaces for most sensors and modules.

Arduino Uno R4 / compatible

Good baseline for beginner wiring and library validation.

Raspberry Pi Pico W

Practical MicroPython target for I2C, SPI, UART, PWM, and ADC experiments.
