Description: PICAXE 28 pin microcontroller chip. Enhanced PICAXE28 chips with 8x memory and many additional features such as I2C bus support. Part # : AXE010x2.
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 look for a place to start with microcontrollers, PICAXE is a great way to go!

revolution should start using an open-source bootloader.
Hmmm, might use this in a Snake game with the small LED Matrix…
I use this in the surface mount package, and would love a US supplier! Once I learned to hand-solder SOIC’s, DIP’s are just too big.
Nice, and it has a lot of PWMs :)
Hmm. in the picture its the PIC18F25k22, but I got the older PIC18F2520. What happened? i there a mix in the stock or something?
I got a pic18f2522. You should get a return or something…
From the data sheet:
IMPORTANT NOTE - this manual describes use of the standard range (3-5V) parts. The X2 parts are also available in special low power (1.8V to 3.3V) variants. Use of a 5V supply on a 3.3V part will permanently damage it!
Which one is this?
Gracias!
Acording to the PIC in the image, this is the 5V version.
Adios!
This is the universal voltage, 5v, 3v3 are no longer in production (according to Picaxe). PIC in image is universal.
True! This is the universal voltage version 28X2 chip (based on the PIC18F25K22). The AXE010X2-5V was replaced by this chip. I wanted to add you can buy the PICAXE-28X2 micro (3V) off the picaxe site.
Is this really the 28X2 chip?
Yes it is, PICAXEs are PIC’s with a bootloader into them, just like Arduinos, thy use AVR microcontrollers with a bootloader.
Are PICs classified as AVRs?
