Apollo2 Blue - Ultra-Low Power System on Chip with integrated BLE
THE APOLLO 2 BLUE HAS BEEN ISSUED AS EOL, LAST STOCK AVAILABLE!
The Apollo2 Blue builds upon the industry's best power management efficiency of the Apollo2 SoC Family with a System-In-Package comprised of the Apollo2 SoC and Bluetooth Low Energy controller to deliver a totally integrated Bluetooth Low Energy connectivity solution.
The device offers Bluetooth 5 ready radio and integrates 1 MB of flash memory and 256 KB of RAM to accommodate radio and sensor overhead while leaving space for application code. This System on Chip also includes several masters and one slave SPI and I²C ports and two UART ports for communicating with sensors including accelerometers, gyroscopes, and magnetometers.
Apollo2 Blue adds top rated Bluetooth Low Energy radio capability to an already-existing aray of relevent functionality built around the Cortex®-M4 processor expressly designed for use in IoT and wearables applications.
