@leonerd @oshpark @benhencke Nice option with display and local control. But if you want really cheap scopes, function generators, counters etc. then the #cvut team from another department provides firmware for cheap STM32, PICO and even Arduino (sic, some people are not willing to move forward and colleagues support them too) boards based Software Defined Instruments. For the PC side, see DataPlotter (github , with Nucleo F303RE 5 Ms/s 12 bit, STM32L412KB 2x 5 Ms/s, with Arduino 15 kS/s, with Raspberry PICO 1x 500 KS/s or 2x 250 kS/s) and older zero_elabviewer for even more boards. All firmware is available for download and documented in theses (unfortunately usually in Czech language, but colleagues or me can help).
