Prototypes - They Work!

Hi all,

I got four prototype boards back from MacroFab yesterday, and this morning I tested them out. They work great! Here’s a pic of all of them hooked up and reading out together - a 16 channel scope!

And here’s what it looks like on the screen. Note how nicely the two identical signals are aligned in time.

I want to fix one minor thing… the micro-USB connector should point towards the back of the board, so the JTAG connector of the board on the right is not in the way! This is useful for powering the boards independently.

Now I just have to work up the courage to hit the “go” button on the remaining 196 boards. :) Maybe tomorrow!

Product Choices

$119

Your very own Haasoscope!

A fully assembled Haasoscope, preloaded with firmware and ready for data-taking! You also might want to grab a USB-serial adapter (for interfacing to a computer) and/or a USB-blaster (for reprogramming the firmware).


$9

USB-blaster

This lets you reprogram the Haasoscope FPGA firmware from either Windows or Linux using the free Altera Quartus II software via the JTAG connector.


$9

A Cool Screen!

This is a 0.96" 128X64 pixel white OLED screen. It communicates with the Haasoscope over an SPI interface, and can show ADC data from a selected channel, or whatever you tell it to! It can plug directly into the header above the FPGA.


$16

Oscilloscope Probes

Two passive 100 MHz bandwidth oscilloscope probes for connecting to Haasoscope 100 MHz ADC inputs using BNC.


$15

High-speed USB Readout Board

In case 1.5 Mb/s is not enough bandwidth for you, grab one of these boards and have high-speed USB2 output from a Haasoscope! Using just 8+2 digital outputs on the Haasoscope, you can get about 4 MB/s, about 20x faster than serial, and still use the same python readout code. It's supported in the stock firmware too! Using 8+4 digital outputs, you could in theory even get up to 40 MB/s using C++ readout code and the free FTDI USB libraries.
