I'm developing a fully featured, low cost, MSO. Schematics and HEX files available if you want to build your own unit.


The Xprotolab is the first mixed signal oscilloscope with an arbitrary waveform generator in a DIP module. It measures only 1.6" sq. inches, and can be mounted directly on a breadboard. The Xprotolab can also be used as a development board for the AVR XMEGA microcontroller.

General Specifications:

• ATXMEGA32A4 microcontroller: 32KB Flash, 4KB SRAM, 1KB EEPROM
• Graphic OLED display 0.96", 128x64 pixels, wide viewing angle
• Module size: 1.60" x 1.00"
• PDI interface
• 4 tactile switches
• Micro USB connector for power (Software USB will be a future update)

Oscilloscope specifications:

• 2 Analog Inputs, 8 Digital Inputs
• Maximum Sampling rate: 2MSPS
• Analog Bandwidth: 318kHz
• Resolution: 8bits
• Input Impedance: 1MΩ
• Buffer size per channel: 256
• Max. Input Voltage: +/- 10V

AWG specifications:

• 1 Analog Output
• Maximum conversion rate: 1MSPS
• Analog Bandwidth: 66kHz
• Resolution: 8bits
• Low output impedance
• Buffer size: 256
• Max. Output Voltage: +/- 2V

Cute all-in-one scope. Quite limited but the small form factor and breadboard compatible footprint is nice.

Is the logic analyser software implemented yet?

I would have ordered one if usps express mail wasn't so expensive (the price of the board itself). Have you considered other usps shipping option? In my experience from SF and various vendors, small untracked envelopes are fast and reliable (at least to France).
Or maybe I can find another guy interested in purchasing one...

The logic analyzer is done except for the protocol sniffer which I will have ready in a few days.
I'll check out the shipping module at my website, but I might not get to it soon. Shipping to France with an untracked envelope is about $5.39. Email me if you want more info.

Hi,

I just received my Xprotolab. I am really impressed by the product.
It's not fair to compare to a full scope or logic analyzer (it's really tiny), but it's really impressive to pack so much functionalities on a corner of a breakboard.
Considering the price, it's really a "nice to have" for the breakboarders.

I will be selling the Xprotolab for just $35.00 on 2011-11-25.

The Xprotolab has gone a long way since this first post in January, lots of new features and improvements.

There have been a lot of improvements in the Xprotolab, I am also working on the Xprotolab Portable.
