Nordic nRF52840 BLE dongle bluetooth 4.0 bluetooth 5.0 for computer

Description

Holyiot-17120 BLE dongle module is based on Nordic nRF52840 Soc, 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 clas security with an ARM CryptoCEll cryptographic system on chip and a full AES 128-bit encryption suite. it also support BLE mesh
