Cheap, flexible, data acquisition for all!

Latest Prototype

The latest prototype is in, and it works! The board has 2 2-channel op-amps now, and 4 digital switches, which allow for 2 gains for each channel independently: +-4 V and +-400 mV. You can also fine-tune the input DC offset, also digitally from the FPGA (PWM baby!). Now it’s just fine-tuning. There’s a bit more noise than I’d like, so I’m trying out a 4-layer board with a dedicated ground plane and some more intelligent routing of the ground current returns.

The software can continued to develop. In addition to letting you adjust the gains and DC offsets per channel, there’s also a new FFT window! It’s all just python, so easy to expand the functionality.

We hope to launch this project VERY soon. Thanks for your support!

Product Choices


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).



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


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.


Oscilloscope Probes

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


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.
