Hello fellow tinkerers and electronics geeks alike! After seeing all the awesome expansion cards that this community has created, I thought that I would dip my toes in the water as well with something that I plan on creating when my uConsole arrives. I dare say I will be be using @Vitaly’s [uPico Expansion Card](https://forum.clockworkpi.com/t/upico-expansion-card/11320) as a very solid foundation for my own card, as there are a couple of Oscilloscope signal reading programs that already exist and are Linux/Pi compatible that can utilise the RasPi Pico IO to receive and potentially even send oscillating signals. Software such as [PiScope](https://abyz.me.uk/rpi/pigpio/piscope.html) is something I’m looking into that could show promise, however I’m still on the hunt for more fleshed out Oscilloscope software that I could interface with. A point of possible issue would be the RF BNC connector that oscilloscope probes use, of which, the uConsole may not fit most styles of on-PCB BNC connectors. I have been looking at the [Amphenol Connex 112640](https://www.farnell.com/cad/2354959.pdf), which is a PCB edge mounted BNC connector, however I am not 100% sure how the Expansion Cards interact with the body of the uConsole. Anyways, this idea is still very early days, however myself, and I would imagine at least a few others could definitely find use in an Expansion Card such as this, and I’d love to collaborate with the community in making this come to life! ---

What about using edge-mounted SMB connectors and an SMB-to-BNC adaptor (or adaptor cable)? The SMB connectors should be roughly proportional to the uConsole size here (the rest obviously is not). ![uconsole-scope](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/7/7d6ce7e1d971616eaaa76786e13b83e455258b60.jpeg) ---

This could be a handy addition. I’ve been mulling over the idea of a digital multimeter expansion card. Something that can log data and be scriptable (e.g. do an action when the voltage crosses a setpoint, or the probes go open circuit, something like that). ---

I definitely like this idea, I was not aware of this smaller standard of RF connections, and it was one of the bigger issues with this idea - trying to fit the BNC connectors. It seems there could be a couple of options for an RF adapter - some more available than others. [SMB edge-mount](https://au.element14.com/johnson-cinch-connectivity/131-3701-801/rf-coaxial-smb-jack-50-ohm-pcb/dp/2932022?st=edge%20smb) - far less available, but a nicer looking solution. [SMA edge-mount](https://au.element14.com/w/c/connectors?st=edge%20sma&gs=true) - your tried-and-true RF connector, that you can get [adapters](https://core-electronics.com.au/sma-bnc-adapter-sma-plug-to-bnc-jack-straight-seeed-studio.html) for to go to a standard BNC connector for a probe. The next question mark becomes; how many channels would we want? Do we want math input channels? In theory it seems we can fit 4 input-only channels, however that will lose us the room for say an output for a signal generator, which could be very helpful for diagnosing audio gear/signal manipulation devices. ---

I often just need 2 analog inputs & you can hook up a small digital logic analyzer through USB, so that leaves physical (and processing) space for some output stuff, if it’s needed.
