Portable oscilloscope expansion card (concept)
A proposed card built on uPico's RP2040 to read signals with PiScope-style software, with SMA or BNC inputs on the edge.
What it takes
- Plug & play
- Soldering
- Purchase required
Difficulty 3 of 3 — advanced.
Details
HGTorin's plan uses the uPico as the foundation and existing Pi-compatible scope software; the thread collects connector options (edge SMA, SMB, BNC adapters). No hardware was shown when posted, so it is a concept to build on rather than a finished design.

Vitaly's open-hardware card puts an RP2040 microcontroller and a GPIO pinout in the expansion slot for sensors, hats and firmware projects.
Three boards that replace the stock adapter and battery board: PCIe NVMe storage, RJ45 Gigabit Ethernet and USB 3.0 (CM5), plus a PWM fan header.
The all-in-one expansion card: RTL-SDR, SX1262 LoRa, GNSS, RTC and a USB hub with internal USB-C; the adapter board adds USB 3.0 and Gigabit Ethernet.
The 2024 original: an RTL-SDR (R820T2), USB hub and real-time clock on one expansion card — the board that started the AIO line.
Plug-and-play KVM: HDMI capture in and USB HID out, so the console becomes a portable crash cart for headless machines.
Zucker's open KVM card based on the yuzuki-hcc HDMI capture design; standard or micro-HDMI input, recessed to fit the case.
