nRF52820

Feature

Bluetooth 5.2 SoC with built-in USB supporting Bluetooth Low Energy, Bluetooth mesh, Thread and Zigbee

The nRF52820 is a System-on-Chip (SoC) offering USB and advanced wireless connectivity in a small package, for HID, smart home, commercial, and industrial applications.

The nRF52820 features an Arm Cortex-M4 processor, clocked at 64 MHz. It has 256 KB Flash and 32 KB RAM, and a range of analog and digital interfaces such as an analog comparator, UART, SPI, TWI, QDEC, and last but not least, USB. It can be supplied with a voltage from 1.7 to 5.5 V which enables powering the device from sources such as rechargeable batteries or via USB. The 2.4 GHz multiprotocol radio is fully featured and provides up to +8 dBm output power.
