nRF52840 Bluetooth 5.0 Evaluation Kit

nRF52840 Bluetooth 5.0 Evaluation Kit

NRF52840 Eval Kit is a development/evaluation kit based on nRF52840, features Arduino / Raspberry Pi connectivity, and several common used peripherals.

It supports the new generation Bluetooth 5.0, compared to Bluetooth 4.0, the data rate is twice, up to 2Mbps, the transfer distance is quadruple. Based on the ARM Cortex-M4F architecture, the CPU frequency achieves up to 64MHz. Bluetooth MESH and 2.4GHz radio are also available, that means higher performance, and more suitable applications.

Thanks to the onboard Arduino / Raspberry Pi compatible headers, both Arduino shields and Raspberry Pi HATs can be attached at the same time, make it easy to use more expansion resources.

Features

• Arduino connectivity, supports Arduino shields
• Raspberry Pi connectivity, supports Raspberry Pi HATs
• Integrates CP2102 USB TO UART, for serial debugging
• Onboard several peripherals and interfaces, convenient for study / development
• Comes with development resources and manual (examples for Bluetooth 5.0 / Bluetooth MESH)
