Description

Flea-Scope™ is a very low-cost and easy-to-use 18 million sample-per-second (Msps) USB oscilloscope and mixed-signal logic analyzer with a built-in waveform generator, and so much more, based on the PIC32MK MCU! Flea-Scope can be controlled by any Chromium-based web browser that supports WebUSB API or Web Serial API running on a computer, tablet, or phone, with no need for further software install – just plug it in and open a web-page and you are up and running!

Additionally, using "deep-dive interactive mode", you can interactively configure 18 user-defined pins, write and debug BASIC programs, and even configure a saved program to auto-run when Flea-Scope is turned on, turning Flea-Scope into the base for your embedded system!  Again, using nothing more than a web-page!

Features and Specifications

  • 1 analog input with 12-bit ADC sampled at up to 18 million samples-per-second (18 Msps), with roughly 4 MHz of usable analog bandwidth
    • 1 full-size BNC connector with 1 Mohm, 14 pF input impedance
    • -6V to +6V input scale with 10 mV resolution (or -60V to +60V input scale with 100 mV resolution when used with x10 oscilloscope probe)
    • compatible with most x1 and x10 oscilloscope probes with full-size BNC connector
    • DC coupling or digital AC coupling
  • 9 digital logic analyzer inputs co-sampled along with the analog input
    • compatible with 3.3V or 5V logic levels
  • auto, level, rise, and fall analog/digital trigger modes
    • delayed trigger/capture capability (0us to 1s)
    • "trigger out" pin allows Flea-Scopes to work together simultaneously for more channels!
  • 1 test waveform output
    • up to 40 kHz for DAC-based sine, triangle, or ekg waves
    • up to 4 MHz for square waves
  • 2% accuracy goal for voltages and timing
  • 1 micro-USB connector
    • full-speed USB isolator-compatible
  • simple web-page user interface
  • dimensions: 1" x 3" (2.54cm x 7.62cm)

And so much more...

When used in "deep-dive interactive mode", Flea-Scope also features: 

  • StickOS® BASIC, an entirely MCU-resident interactive programming environment, with built-in:
    • program editor
    • line-by-line compiler
    • interactive debugger, including edit-and-continue
    • performance profiler
    • flash filesystem
  • 120 MHz PIC32MK0512GPK064 MCU
    • 150,000 BASIC lines/second performance
  • 18 fully programmable and interactive multi-function I/O pins, configurable for autonomous:
    • digital input/digital output
    • analog input/analog output (PWM)
    • frequency output
    • servo output (PWM)
    • I2C master mode
    • SPI master mode
    • UART input/output
  • 2 user-controlled LEDs and 1 push-button switch
  • compatible with 0.1" (2.54mm) solderless breadboards!
  • simple web-page user interface
  • customized hostname setting (to distinguish multiple Flea-Scopes on the USB and thru the user interface)
  • firmware upgrade support

Package List

The Flea-Scope package includes:

  • Flea-Scope PCB with micro-USB connector and full-size BNC connector and 0.1" (2.54mm) PCB holes for logic analyzer inputs, waveform output, and deep-dive multi-function I/O pins

Note that Flea-Scope does not include a micro-USB cable or an x1/x10 oscilloscope probe, nor 0.1" (2.54mm) header pins, nor a computer, tablet, or phone -- you will need to provide these yourself.

Compatibility

I test Flea-Scope with Windows, macOS, Linux, ChromeOS, and Android.  On macOS, you might get better performance using the "manual" webpage to select Web Serial instead of WebUSB.  I test with Google Chrome and Microsoft Edge browsers.  For more information on WebUSB and Web Serial used by the Flea-Scope GUI web-page, see: https://wicg.github.io/webusb/ and https://wicg.github.io/serial/

I do not believe any iPhones or iPads yet expose USB devices thru WebUSB or Web Serial into the browser JavaScript, so they don't yet work with Flea-Scope.  Some Samsung phones claim the USB device with their serial driver, but do not subsequently expose Web Serial into the browser, leaving the USB device inaccessible to JavaScript.
