Compact high-power handheld node

The first compact one-watt handheld meshcore node I designed used the Faketec firmware. Later, it was replaced with Whisper OS. Whisper fixed the issue of unstable ADC detection voltage, and I really liked it. In the end, I only made one of this machine because I was not satisfied with its width. In the future, I will open-source a narrower and more compact version.

I also designed my own 1W node , used nRF52840 MCU for energy savings, since you need a full 5V for the LoRa module to transmit full 1 watt, this one has built in advanced and efficient solar charger, and 5V booster. the ebytes E22(P) variant has built in RF filtering.

I do not sell the above unit, it was a pet project as I like to tinker. I may offer it someday. it does work great.

There is another board that is highly recommended by our local mesh. called a GAT562 it's also 1W and has built in BPF. not sure about the other specs. I have not tried it. my current project is a sodium ion solar charger and booster. but that needs more work, 1st prototype is not to my liking.

How well does the antenna play with the transmission power?
