Description: This is the PICAXE-20M2 microcontroller chip.

PICAXE is a neat entry-level microcontroller system that is relatively cheap to get started with. The chip is programmed with a simple serial connection and the BASIC development environment is free! PICAXE has some excellent educational applications and support, and is a great entryway into more complicated embedded systems. If you’re looking for a place to start with microcontrollers, PICAXE is a great way to go!

  • There are times when I do not order from Sparkfun because they don’t stock the 20x2. Instead I order from Solarbotics because they do carry it and I don’t really care to pay extra for shipping if I don’t have to. So I bundle up an order to hit the $100 minimum for Solarbotics. Those are orders I would be sending to Sparkfun because I like your overall selection better.

    If you want to do any serial work, the 20x2 is far better with a 128 character buffer. the 20x2 also incorporates the owin and owout commands if you want to do something besides measure temperature with 1-wire devices.

    It would be awesome if PICAXE would just combine the two into a single device that has all the advantages of both the x2 and the m2. (And then sparkfun would stock that chip) ;-) The 28x2 is that chip but at almost 2 times the price. The 20x2 is the best bargain in the picaxe line.

  • There’s one huge advantage the 20M2 has over the 20X2….two words…“parallel tasking”.

  • 20X2 is a better chip…it should not be retired…please stock the 20X2 along with the 20M2.

  • where is the 20X2? It has more advnced features and program size, and you still have the outdated 28X1s and 40X1s why keep those without the current 20X2?!

  • Hi, just wondering if the 20X2 could be taken out of retirement– the 20M2 is newer but the 20X2 has more program space and a faster internal clock speed, and would be more suitable for some applications. I would buy one.

    • We’ll take a look at it, but I wouldn’t hold your breath. Unfortunately, the 20X2 was simply too slow of a seller for us to keep around, which is why it got retired initially from the catalog.

  • ETA for 20X2???

I’m assuming that because the PICAXE is loosing ground to the Raspberry Pi computer; that this would be the reason for pushing up the price of the PICAXE.

It doesn’t appear that this product has had any changes made to it in a number of years. I don’t believe the price has been modified from the records I am seeing. Thanks
