Haasoscope v9.0 open-source 4-channel high-speed USB oscilloscope bundle

Description

Haasoscope is the first open-source, open-hardware, high-speed, USB oscilloscope. As seen on CrowdSupply!
You can use the stock firmware for basic oscilloscope functionality, or modify the firmware to customize what the Haasoscope does. You can add a fancy trigger algorithm, use the FPGA to process the input data, make use of other analog or digital I/O channels, or whatever. And just connect two or more Haasoscopes together if you need more input channels!
This bundle comes with 1 Haasoscope + 2 oscilloscope probes + USB blaster (for optional firmware reprogramming) + mini-screen + micro-USB cable.

This is the updated v9.0 board, with wider spacing of the BNC inputs, proper 10x probe compensation, and auto-detection of super-gain switches and 50/1M Ohm termination!
Features and specs:
4 high-speed ADC channels, up to 250 MSPS each (for 2 channels), 8-bit, ~100 MHz max bandwidth, BNC inputs
Intel/Altera MAX10 FPGA with 8k logic elements and 387 kb of memory (enough for 8k samples / channel for each event)
Reprogram firmware over JTAG with free Altera software for Windows or Linux (or Virtualbox on Mac)
Python user software for waveform display and control of all features, including FFT, XY plot, measurements, etc.
4 gains per channel: +-3.5 V, +-0.35 V,  +-35 mV, +-3.5 mV ranges, with programmable full-scale DC offset and <1 bit RMS noise
Switchable AC/DC input, 50/1M Ohm termination for each channel
Readout over serial at 1.5 Mb/s, about 20 Hz for four channels of 512 samples each, works with PCs (Win/Linux/Mac), Raspberry Pi, Arduino, etc. - and now even an Android app!
Serial decoding via ripyl python library
