As the world of smart connected devices grows so does the Bluetooth standard. Our newest click board – RN4870 click – carries a Bluetooth® 4.2 module from Microchip.
RN4870 click carries the RN4870 Bluetooth® 4.2 low energy module from Microchip. The module contains an integral ceramic chip antenna.
The click board is designed to run on a 3.3V power supply. It uses ASCII Command Interface over UART for communication with target microcontroller.
Bluetooth Low Energy and IoT
Sensors, gas meters, light switches, and other smart devices sending small amounts of data - all these devices need to be connected to the cloud. Thankfully, BLE has very low power consumption. No more drained batteries and devices shutting down.
RN4870 click has the average current consumption of 0.23mA in standby mode and 2.77mA when data transmission is in progress. You can start designing an IoT project without worrying about the battery.
