Cypress' solar-powered Internet of Things (IoT) device development kit provides an easy-to-use platform for the development of a solar-powered IoT device with Bluetooth® low energy (BLE) wireless connectivity. It includes the S6AE101A energy harvesting PMIC device. Also included in the kit is Cypress' EZ-BLE™ PRoC™ module (CYBLE-022001-00), a fully integrated BLE module solution that offers high flexibility for a wide variety of IoT device uses. A USB port is provided by Cypress' USB-UART LP bridge controller device (CY7C65213).
Features
The solar-powered IoT device kit provides everything needed to develop a light-powered sensor node that transmits sensor data using BLE:
|
- Firmware provided for the following applications:
- BLE beacon, transmitting data at 1.5 sec intervals with ambient light as low as 200 lx
- Wireless sensor node (WSN), transmitting data at 6 sec intervals with ambient light as low as 200 lx
- BLE communication with a PC supported through the included BLE-USB bridge that is pre-programmed with custom firmware for this kit
- Operation using energy harvested from light as low as 200 lx supported with the included solar cell module, which eliminates the need for a battery
- Use of a vibration energy harvesting device with an external diode bridge also supported (not included)
|
|
- Reference schematic, BOM list, and layout data provided
- Expandable terminal on the energy harvesting motherboard provided, enabling support for the following:
- Reset button for EZ-BLE module
- JTAG header to debug EZ-BLE module
- Expandable sensor interface (I2C/UART/SPI/GPIO)
- DIP switch for future expansion (not mounted)
- LEDs for USB power and status
