      For all my fellow tiny-adorable-computer aficionados. It uses a fairly beefy RISC-V embedded CPU, a custom OS derived from other products the creator has made (mostly hackable event badges, apparently), and a keyboard and display that might actually be worth using. Very tempting toy, it would be fun to get a couple and make a little LoRa broadcast-chat application or something.

      1. 2

        I immediately thought you must have been misinformed, but you’re absolutely correct, the ESP32-P4 is in fact a RISC-V chip, unlike the other members of the ESP32 family! That’s awesome.

        I’ve been seeing these lightweight LoRa devices with mini keyboards popping up lately; here’s a recent Lobsters story about an OS for a few of them which also use ESP32. This looks like the best of them so far. Very interesting!

          The ESP32-C and -H lines are RISC-V as well; Espressif seems to be generally meandering towards using RV everywhere? Meanwhile, in the best traditions of hardware manufacturers making absolutely baffling branding decisions, the ESP32-S series still uses the Xtensa architecture.

          1. 2

            Didn’t know about the H or P series. I’m sort of shocked that the P4 doesn’t have built-in WiFi and BT, since that’s kind of been ESP’s bag since the first 8266.

            (I find it sort of funny that even a tiny cheap device like this has 3 separate CPU chips in it!)

          how is one supposed to do anything real on that tiny keyboard though?

          1. 3

            These little thumb keyboards, when done well, are considerably more ergonomic than an on-screen virtual keyboard. At least, that’s been my experience. I miss the Blackberry and Nokia keyboard phones, and was definitely doing “real stuff” with them at the time.

            1. 1

              Same way one is supposed to do anything real on a phone keyboard: control your expectations. :-P I don’t expect the device to be used for 6-hour coding sessions, and there’s better devices than it for gaming, but it’s nice to have a keyboard for general purpose stuff or maybe light chat. If you’re using it for fun hacking or maybe Flipper-like wireless exploration, the keyboard seems just fine.
