Masters-Multi-Channel_DAQ
Blaze-Pascal
Custom 2-channel digital oscilloscope DAQ with 20MHz bandwidth. Built with a custom KiCad analog front-end (AFE) PCB, Gowin FPGA (Tang Nano 9K) for high-speed signal buffering (VHDL), and an RPi Pico MCU for SCPI-like control. Includes a simple Python GUI for data visualization.
