The Raspberry Pi foundation recently (about a 18 months ago) released their own dual-core ARM chip - the RP2040 - and a corresponding dev board - the Pi Pico. The Pico dev board runs about $4 plus shipping from authorized resellers. Within the past few weeks, they introduced a wireless version - the Pi Pico W. It's about $6 from authorized resellers, though stock is hard to find at the moment. https://www.raspberrypi.com/documentation/microcontrollers/ https://www.raspberrypi.com/documentation/microcontrollers/ https://www.raspberrypi.com/news/raspberry-pi-pico-w-your-6-iot-platform/ https://www.raspberrypi.com/news/raspberry-pi-pico-w-your-6-...

Esp32 boards has 2 cores and cost $5, works fine in Arduino. Try AliExpress.

  And can use up to 8mb of psram and 16mb of flash

    also can interface to sd cards easily for gigabytes of mass storage

  Showing some Teensy love, crazy the 4.0 has 600MHz base speed.

    Is that a Cortex-M7 or something?
    - ge96 4y ago
      Yeah that's what it says. I like it because it has so many connection pins eg. i2c/can be lazy. I have STM32 and Beaglebone too but have not used them yet.

    Teensy is great, but that puts you in the $20 range and doesn't have WiFi.
    - ge96 4y ago
      In my case I just use an ESP01 to add WiFi.

  I forgot to mention, blinky demo compilation take 60s on my PC, that's the only downside but maybe there are some workarounds.

Well, there's a "hardware" link at the top of the linked article for starters. Or google "esp-32" to find store selling a very popular one. Or check out what's available on sparkfun or adafruit.

  I’m a fairly loyal customer of adafruit. I really like their stuff and I’m not ashamed to say I really like circuit python. So much of embedded work is writing drivers and circuit python has many many already written and ready to go.
