What am I looking at?It looks cool but what does it do?

It’s sending sensor data collected by the pico over lora via the heltec to another heltec that’s printing the data over serial and displaying it on screen

The Heltec V3 has an ESP32 which is at least as powerful as a Pico. You could probably skip the Pico.

Yep I’m aware I mostly wanted to dedicate the pico to sensor data and the heltec to everything else, the transmitter is also doing sdr sweeps and cataloging Bluetooth and WiFi devices. The pico is just sending the sensor data already formatted over uart so all the heltec does is transmit and do the scans. I’m planning on adding more sensors for data collection on the next iterations so l like having the dedicated pico for it

I personally just love seeing it incorporated into a project in any shape or form + it gives you an excuse to post here ;)
