Ricoh Electronics RIOT-001 Environment Sensing Board | New Product Brief
This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
Ricoh Electronics RIOT-001 Environment Sensing Board
Ricoh Electronic Devices’ RIOT-001 Environment Sensing Board demonstrates Ricoh’s high-efficiency power management ICs for use in IoT edge devices. The RIOT-001 includes sensors and a BLE module to transmit sensor data to a tablet or other device.
The board is designed for independent operation from a solar panel, which supplies the Ricoh R1800K series energy harvesting buck DC/DC converter that has low quiescent current and low starting power and optimizes charge current to a small secondary Li-ion battery. The Ricoh RP604, a low current buck-boost regulator, provides a stable output to power the sensors and BLE module.
The RIOT-001 also transmits the secondary battery voltage over BLE, which is measured by Ricoh’s RP124, a low current LDO with integrated battery monitoring.
- Sensors: BME280 Temperature/Humidity/Pressure sensor and MAX44009 ambient light sensor
- Designed for solar panel energy harvesting (solar panel not included)
- R1800K Series DC/DC Converter: Low IQ (144nA) and low starting power (720nW)
- High-efficiency energy harvesting works in low light environments
- RP604 Buck-Boost DC/DC Converter: Low IQ (300nA) and low standby current (10nA)
- Ideal for devices primarily in sleep mode
- RP124 LDO with Battery Monitoring: more efficient battery monitoring than using a resistive divider
