PICAXE 28X2 Microcontroller (28 pin)

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!

PICAXE 28X2 Microcontroller (28 pin) Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

2 Soldering

Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Customer Comments

  • 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?

  • 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?

    • Acording to the PIC in the image, this is the 5V version.

      • 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?
