We love the Raspberry Pi, but for many projects it's too much. The ESP32 and Raspberry Pi 2040 chips are great for low power and have enough processing capability to do AFSK and other audio modems. The Meshtastic protocol runs on ESP32 with a LoRa chip, for example. I can run a node (that can perform double duty as an MQTT gateway) on a single 18650 for over a day easily. Add a small solar panel and it can operate indefinitely. I think that the amateur radio community should consider some of these other chip options, especially for interfacing with mobile devices that can do a lot of the heavy lifitng.

As for the "No Winlink!" folks... 🙄 No one wants to bother with HF email.

Thank you for sharing all of these sections (replying to the Cheap Data Radios section, but loved the Satellite section and many more!)
