Product Description
Long Range FCC CE Ipex BLE Module BT5.0 nRF52840 Wireless Wifi Module
The RC52840B is Bluetooth Low Energy (BLE) module based on Nordic NRF52840 SoC solution. The nRF52840 is designed around an ARM Cortex-M4 CPU with floating Point unit (FPU) and has 1MB flash with cache and 256kB RAM. As such it has the ability to support complex and demanding applications as a single chip solution. It offers a wealth of peripherals that include NFC, USB and multiple interface options including Quad SPI (QSPI). Security is paramount in today's IoT designs and the nRF52840 has high-end security features included to achieve best in class security with an ARM Cryptocell-310 cryptographic system on chip and a full AES 128-bit encryption suite.
