Frameoscope
Frameoscope is a fully open-source oscilloscope implementation in the form factor of a standard Framework Expansion Card, developed by jlcjak. It samples at 40 MSPS with 10 MHz bandwidth, using a Texas Instruments ADC, an iCE40 FPGA, and an FTDI FT232H USB PHY. It is compatible with ngscopeclient, the open-source streaming oscilloscope client. The FPGA also serves as a user-programmable module with a >40 MB/s bidirectional data link to the host.
