For our new prototype, I’m considering the nrf5340. It has hardware AES 256 acceleration, 1 MB flash, 512 kb ram and a dual core CPU. We can use the slower core for usual stuff, and the high power one for heavy lifting.
The new device we’re making needs to be flexible so it will support both EU and US frequencies, at 500 mW and 1 watt respectively, license free while also supporting SMA antennas. If you enter a ham ID in the EU, we will unlock the 1W mode in EU too.
This will limit our frequency range but allow a higher duty cycle and power limit. For lower power limit, we will unlock all the normal frequencies meshtastic usually does.
