A single RP2350-based device called PicoLab, built by Max.K, replaces four pieces of bench equipment: a four-channel oscilloscope, an eight-channel logic analyzer, a data logger, and a multi-protocol serial interface covering UART, SPI, and I2C. It also includes an adjustable power supply and configurable GPIOs.
The hardware uses the larger RP2350 package for its expanded pin count, paired with custom protection and interface circuitry. The interface is a web app served directly from the device over USB networking, meaning any machine with a browser and USB support can drive it with zero driver installation.
All code is public on GitHub. The full article is worth reading for the circuit design choices and the USB networking approach, which is the kind of zero-friction host compatibility solution that most commercial tools still have not figured out.
