Overview
NRF52840 Eval Kitis 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.
Only one NRF52840 module is included in the kit, it should be noted that at least three NRF52840 modules are required for Bluetooth MESH networking.
