Can anyone recommend a #RasPi alternative for #embedded #electronics projects? There's the #Arduino, which is nice, but sometimes you need something with a little more oomph.
@me ESP32 has a pretty beefy CPU for a microcontroller, packs much RAM and comes with Wi-Fi/BT.
@RicoElectrico @me I'll second the recommendation on ESP32. I probably have 10 of them now and they are quite capable.
That said, the Pi Pico is decent too, especially if you have unusual high speed signaling requirements.
@rayk I don't expect especially high speed signaling to be a requirement. I do want to be able to establish a TCP connection to a PC over wifi, though.
@me @rayk my current project is doing just that and with #esp32
[edit]
This setup uses a handful of #esp8266 with sensors, all in a mesh with network, plus one esp32-c3 as the bridge to the normal home WiFi network, and a #RaspberryPi Zero for data storage

Since this one works, I ordered a few more sensors and microcontrollers from the same manufacturers and I soldered them
I now have a bunch of these little devices around the house, and I am very happy with how they extend the range
As long as I place enough of them along the way, I can sprinkle them wherever I want and they’ll self organize, and one of them reports all their readings to an SQLite database on a RaspberryPi Zero
They are on their own WiFi, which doesn’t matter for security since I’ve written their program myself, but still feels great
Haven’t done statistics and graphs yet
