Streamoscope
About the Streamoscope PCB
Streamoscope is an open source PCB design by JosephFeld, published on GitHub under the MIT license. It is a 4-layer board measuring 85.4 × 157.2 mm, with 132 components from 38 distinct parts.
Other key parts include the MIC7221YM5-TR, TPS767D318PWPR, FT601Q-B-T, HD3SS3212IRKSR and AFE5812ZCF. By type, the board carries 79 capacitors, 16 resistors, 15 connectors, 9 inductors, 5 ICs and 2 crystals.
From the project
USB-3 streaming data acquisition system originally designed for low-field MRI
It reads in 8 channels of data from the AFE5812 analog front end chip into an Alchitry Au FPGA board, which feeds it into an FT601 FIFO-to-USB-3 Bridge which can be read into Python. Due to bandwidth constraints of the FT601, it only streams two channels. However, more could be streamed with a modified FPGA design that decimates the signals or decreases their precision.
