MSP430 LaunchPad 4 channel logic analyzer update
OPossum already designed a MSP430 LaunchPad logic analyzer based on our Logic Shrimp. In the latest update he decided to follow our lead in changing the 4 23K256 SRAM ICs for a single 23LC1024 IC. Preliminary design of a 4 channel version using the new 23LC1024 SPI RAM. Hope to find some time this weekend […]
3D Model: Logic Shrimp v2b
Today’s 3D model is the Logic Shrimp v2b. The newer version uses the single 23LC1024 SRAM instead of four 23K256, and the serial data lines (SD0 – SD3) are now bi-directional. The Logic Shrimp is a 4 channel, medium speed, low cost logic analyzer with 256K samples and 20MHz top speed. Check out our tutorial […]
MSP430 Launchpad Logic Analyzer based on the Logic Shrimp
oPossum built a 6 channel logic analyzer booster pack for the MSP430 Launchpad. His design is inspired by the Logic Shrimp and used SPI serial interface RAM chips to store samples. The MSP430 software is SUMP compatible and works with Jawi’s OLS client. This is a logic analyzer add-on for the TI MSP430 Launchpad. It […]
Logic Shrimp logic analyzer back in stock
Logic Shrimp is back in stock at Seeed Studio. You can get an assembled Logic Shrimp for $34.90.
3D Model: Logic Shrimp v1.0b
Our latest 3D model is the Logic Shrimp v1.0b. Recently we stumbled across Kerkythea, an open source alternative to the Maxwell for Google SketchUp software we’ve been using to render our images. It is an image and video rendering software with an export plugin for SketchUp. It is a little more complicated to use, but […]
Logic Shrimp laser cut case
Anders designed a laser cut case for the Logic Shrimp from 1/8” acrylic. The top was made for light pipes instead of LEDs. A short description, instructions, and a cutting template are available. More cool DIY cases here. Via the contact form. You can get an assembled Logic Shrimp for $34.90.

All through-hole version of the Logic Shrimp
jarin made an all through-hole version of the Logic Shrimp logic analyzer: I’ve made variation of Logic Shrimp, using only through-hope components found in my junk box. More details and pictures can be found here. There is no schematics drawn, I built it just using datasheets and original schematics – and I’m too lazy to […]

Maker Faire 2011: Hands-on DIY festival
The internet situation pre-Maker Faire Bay Area has been pretty bad. Worse than bad. Today we’re in the conference hotel though, and there’s wired and wireless internet aplenty. If you’re going to Maker Faire please stop by the Seeed Studio booth and say hi, we’re right next to the central Maker stage in the main […]
Logic Shrimp release package v2.0
Over the last few weeks we did a massive cleanup and reorganization of our SVN code repository. Most projects now follow a standard directory structure. All our in-progress and stalled project files are now completely open and available to anyone. We also included all the manufacturing resources used to initiate production at Seeed, and the […]
Free PCB Sunday: Logic Shrimp logic analyzer
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This week we’re giving away two […]
NEW PROTOTYPE: Logic Shrimp logic analyzer
The Logic Shrimp is a medium speed, low-cost logic analyzer with a USB interface. It can capture up to 256K samples at 20MHz, and is compatible with the open source SUMP logic analyzer client. The 23K256 serial SRAM from Microchip makes this project possible. Each chip stores up to 256K samples from one logic analyzer […]
