Smart Solar Camping Lantern with USB-C PD

Smart solar camping lantern with rugged rubber frame

Droid Technologies designed and developed a smart solar-powered camping lantern with smartphone control, USB-C Power Delivery, solar charging, motion sensing, and power-bank functionality.

The device is based on the Nordic nRF52840 and uses Bluetooth Low Energy (BLE) for smartphone control of light brightness and color. The lantern can be charged through USB-C PD or an integrated solar panel, while the internal battery can also charge external devices through USB-C.

Droid Technologies provided hardware design services, firmware development, PCB design, power electronics, BLE integration, USB-C PD implementation, battery management, solar charging electronics, motion sensor integration, and LED driver development.

Key features:

• Nordic nRF52840 MCU
• BLE smartphone control
• Adjustable brightness and color
• USB-C PD input and output
• Integrated solar charging
• Power-bank functionality
• Motion sensor
• Battery management and protection
• LED driver electronics
• Custom PCB and embedded firmware

This project demonstrates Droid Technologies’ expertise in smart lighting development, Nordic nRF52 firmware, BLE devices, USB-C Power Delivery, battery-powered electronics, solar-powered embedded systems, power management, and connected consumer electronics.

Droid Technologies provides hardware design services, firmware development services, PCB design, embedded systems development, power electronics, IoT development, mechanical design services, prototyping, and full-cycle electronic product development.
