nRF5340 (nRF53 series) support?

[Hedda]

nRF5340 is the latest SoC from Nordic Semiconductor with Zigbee support (combining all features of nRF52840 and nRF52833)

It features 1 MB Flash + 512 kB RAM, and it provides better RX sensitivity (less sensitive to EMF/RMI noise) while using less power.

"The 0 dBm TX current is 3.4 mA, while the RX current is only 2.7 mA, resulting in a reduction of 29% and 41% when comparing to the nRF52840 SoC. The RX sensitivity is -98 dBm, 3 dB better than nRF52840, meaning that the nRF5340 provides 3 dB better sensitivity, while using 41% less current."

Other than using about half the power, another reason why you might want to add support for it is for its nRF5340-DK development kit:

Ebyte/cdEbyte have an E83-2G4M03S SMD radio module as well which can be found on their E83-2G4M03S-TB evaluation board

Initial goal of the project is to support nRF52840 based devices, with expansion to nRF53 series.
