Description

Editor-in-Chief of Embedded Computing Design, Brandon Lewis, unpacks the Indoor Solar Development Kit with Nordic BLE.

 

The Indoor Solar Development Kit with Nordic BLE (DEV-IN-BLE-NS) is perfect for developers looking to design or add PowerFilm’s high-performance indoor solar to BLE products.

 

The kit works out of the box and operates at extremely low light levels down to 200 lux and below. It includes an onboard energy harvester/power management IC, BLE circuitry, Indoor Solar Panels, and all required components to be plug and play. It also includes a custom onboard capacitor charger (“Cap-Charger”), enabling operation without a storage element.

 

This development kit is fully compatible with Nordic’s development tools and connects to the simulated Heart Rate Sensor Demo in the nRF Toolbox mobile app.

nRF52832 Nordic BLE Module

Fully functional BLE module configured for ultra-low-power operation. It connects to iOS and Android devices through Nordic’s Heart Rate Sensor example in the nRF Toolbox mobile App.

  • iOS and Android connectivity

  • IO Break-out connectors for additional sensors or components

  • Segger Embedded Studio project solution files

  • Small footprint with compact meandering antenna design

 

Energy Harvesting Modules

The Indoor Solar Development Kit with Nordic BLE comes with the two charging circuits detailed below. The first is a custom battery-free capacitor charger (“Cap-Charger”) and the second implements TI’s BQ25570 energy harvesting/power management IC and is identical to the Indoor Solar Development Kit (DEV-IN-BASIC). The desired charging circuit can be chosen with jumper J1.

 

Cap-Charger

This custom circuit allows the Indoor Solar Development Kit with Nordic BLE to operate without a storage element connected, instead using two 220uF surface mount capacitors.

  • Up to 2x performance vs standard energy harvesting IC solutions

  • Rapid charging during initial off state (0-2V)

  • Low voltage load disconnect with hysteresis and high voltage charge termination

  • Low cost and small footprint

 

BQ25570 Energy Harvesting and Power Management IC

This module is identical to the Indoor Solar Development Kit. The BQ25570 IC uses nano-power boost charging technology to efficiently extract energy from the indoor solar, while the integrated power management can be configured to charge a connected storage element and also provides a power output to connect external electronics. Compatible storage elements include Lithium based rechargeable batteries, thin-film batteries and supercapacitors.

  • MPPT Input with low voltage boost converter

  • Integrated battery charger (default 4.2V Li-ion) with low voltage load disconnect and high voltage charge termination

  • Regulated power output (default 3V)

 

What’s Included?

Everything you need to begin developing an indoor solar-powered BLE device.

  • DEV-IN-BLE-NS circuit board assembly

  • (2) LL200-3.6-75 high performance indoor solar panels w/ leads

  • 40mAh rechargeable Li-Polymer battery

  • Instructions, hardware and software files, and other documentation

 

Use Cases

Wireless connectivity is now standard in modern electronics and the growing IoT and sensing industries. Many applications in this area are very low power and can run completely off a solar energy harvesting solution.
