NEW PRODUCT – Propeller Platform USB. The Propeller Platform USB is an open-source platform for building your own electronics projects with the new 8-core Parallax Propeller chip. This development board has the programming/debugging interface built in along with a microSD card slot.


  • Design your project in Spin, a custom programming language perfect for beginners (tutorials)
  • Collaborate with your PC, built in USB lets you update programs or share data with your computer
  • Interact with the real world, 32 I/O pins let you read tons of sensors and control multiple devices
  • Output video or advanced audio, Built in video hardware makes video easy, microSD lets you include Hi-Fi audio samples
  • Expand with any breadboard or protoboard, use a custom designed module, or create your own

What Can You Do With the Propeller Platform USB?
Turning Stuff Off and On:
32 I/O pins means you can connect to many devices at the same time – multiple LED's, real-time clocks, switches, and relays. It's easy to control dozens of devices.

A unique architecture lets you simultaneously control multiple motors and read multiple sensors. Take a look at the Spyder, an auto-balancing quadcopter running on the Propeller. A screw terminal power connection helps to connect a battery, and the ultra low dropout voltage regulator runs with as little as 5.5V input power.

Make Videogames:
If you want to make your own games, adding video output is as simple as using 3 resistors and an RCA jack. Games like X-Racer are possible, and you can output video in PAL, NTSC, or even VGA. Advanced sound capabilities let you enhance your game, too.

Advanced Audio:
Playback 16-bit stereo wavs stored on the microSD / SDHC card, output TOSLINK (optical) SPDIF audio with a standard LED, or create your own digital effects.

Expansion Options:


  • 80Mhz 8-Core Parallax Propeller with removable 5MHz crystal
  • 64kb EEPROM for long-term program and data storage
  • 5V and 3.3V 1.5A Voltage Regulators accept 5.5v min. power input
  • Comes with a 2.1mm barrel power jack connector and screw terminal connector
  • 2.8" x 2.5" footprint with pin sockets to add additional Platform modules or connect to a breadboard.

The Propeller Platform USB comes pre-assembled – you just a 5.5v-12v power adapter and a mini-B USB cable.


The Propeller Platform USB is designed and assembled in California.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Is there a reasonable open source toolchain for the propeller chips yet? I love the idea of the propeller, but when I checked it out a year or two ago, the only programming option was an awful Windows-only program, totally proprietary, with no source code. It looks like Parallax now recommends someone’s hobby project, which is a reimplementation of said awful Windows-only program, but which runs on OS X, Linux, and Windows (also closed source).

  2. Are there any open source programmers/IDE’s for this board?
    bst (and related tools) are free for download, but not open source, are they?

  3. Hey Guys!

    There are a ton of programming options (check them out here: For IDE’s, most folks use BST or the Propeller Tool, which are both free, but not OSS. If you wanted a completely OSS toolchain, I would probably use propasm or catalina, but there are other options, too.

  4. And if you’re so inclined, there’s PropellarForth.

  5. Would it be possible to run .NET MF on it?

  6. Hey David – Other folks have asked about .net micro for the Prop ( ). I think the consensus is ‘it’s possible’, but there are no implementations just yet. There is an awesome JVM for the Prop, though!
