Prototype: Openbench Logic Sniffer logic analyzer

 2010 02 Ols-Cover

Prototype: Openbench Logic Sniffer logic analyzer @ Dangerous Prototypes – nicely done Ian, and Jack Gassett at the Gadget Factory as well as all involved!

Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. Download the source and design files from the Gadget Factory project page.

This project started in the comments on a post. Initial circuit design, PCB layout, development, and testing continued in the forum under the code name Project SUMP PUMP. Many, many people contributed ideas and advice, the Gadget Factory and Dangerous Prototypes coordinated circuit development and routed the PCB. We borrowed heavily from the Gadget Factory’s Butterfly Platform.

The Open Logic Sniffer is a purpose-built logic analyzer board designed to be low cost but high speed. It sacrifices a lot of the features you’d look for in a full-scale development board to achieve our primary goals:

* 70MHz+ sample speeds
* 32 channels
* 16 buffered, 5volt tolerant channels
* USB interface, USB powered
* USB upgradable everything
* Make it as DIY as possible
* Make it as open source as possible
* $30-$40 price range

We didn’t quite hit our initial price range, but we got really close.

You can get your own assembled Open Logic Sniffer at Seeed Studio for $45, including worldwide shipping. Continue reading about the design and collaboration below.


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 code.org, 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. Thanks for the post! Don’t forget Jack Gassett at the Gadget Factory. It was a team effort, and a ton of other brilliant people lent their experience and insight to the effort.

  2. Just Pre-ordered one.. Looking forward to giving it a try! Great price for a hobbyist!

  3. WOOOOT! I have been waiting for this for quite some time…

    Gonna preorder tonight! 🙂

    Should also make a decent generic FPGA dev platform with a few tweaks to the PIC firmware…
