Boost-converter evaluation board for wireless sensors
The R-78S Evaluation Board (R-78S3.3-0.1-EVM-1) maximises run-time by generating a regulated 3.3V output as the battery discharges to as low as 0.65V. In addition, test points for measuring load current and voltage help predict the application’s run-time in active and standby modes. There is also a holder for users to insert a 1.5V AA battery, which can store more energy than the coin cells often used to power plug-and-play IoT modules. Combining the extra battery energy, run-time predictability, and the R-78’s low-voltage boost, this board lets users significantly extend the operating window of devices like wireless sensors. To make this flexibility easily accessible for IoT-device developers, Dengrove is also stocking the R-78S3.3-0.1-EVM-1/STM-1 breakout board for connecting the R-78S Evaluation Board to the STMicroelectronics SensorTile module. The SensorTile combines MEMS inertial sensors, pressure, temperature, and humidity sensors, and a digital microphone, with a Bluetooth Low Energy (BLE) radio module.
