From the project
A 1-Channel 20MHz 100MS/s Mixed-Signal Digital Storage Oscilloscope on a custom 4-layer PCB. Powered by STM32H7, Lattice iCE40 FPGA, and USB-C
The project is made of three parts that were designed together, because each one constrains the others: the PCB decides what the firmware can do, and the heat generated on the PCB decides how the enclosure is built.
I have designed the PCB starting from an STM32H7 microcontroller because of its support for external SRAM and it can directly control the main 7 Inch display with high speed transmission data. The entire board runs using a single 5V usb-C connection and then internally this becomes 3.3V, 1.2V and ±5V. The board includes connections for: - A standard BNC input for oscilloscope…
