The Raspberry Pi Pico blows the Arduino out of the water in terms of computational speed, available RAM and so on, and it costs a fraction. I don't remember using an Arduino since the Pi Pico came out. And if the Pico isn't enough there are the bigger family members waiting in the wings. For me Arduino is mostly over. And then there is Espressif as well, they make some neat boards.

Long live Teensy [1]!

I just wanted that someone mentioned these Arduino-likes in the comments. I suspect many of you have come across them though.

    The teensy is so weird though. At least back when I played with them. They put a secondary chip which let's you flash over USB but they cover the debug pins and the only way to get serial over the USB port is to have a whole USB stack as part of your application. As a development board I would rather go with one of those STM32 backed boards and a knock off STLink, you need the STLink to flash, if you want DFU you can add that yourself, and you get a debug adapter.

      Could you clarify what you mean about getting serial over the USB port in the context of debug pins?

      I've been using Teensy devices for over a decade and have always had it just recognize the device as if it were a USB to serial adapter and I can talk to it as what I'd call "serial over the USB port". But that obviously doesn't involve what I think software people usually mean when they're talking about firmware debug -- which usually entails stepping through execution, right?

      I'm used to just printing debug statements to the Serial.println() function, I learned on the 8051 where the best bet was to toggle different pins when code lines are passed, so even Serial.println() was a huge step up.

    Yes, the Teensy is pretty impressive too. I've used one in a project and came away impressed.

Do you mean the Uno specifically? There are a lot of Arduino boards with varying capabilities.

    For everything Arduino offers that I've ever used I know of a cheaper board with better specs.
