Hi everyone,
I’m excited to share a new open-source project we’ve been working on that we think will be a great addition to your lab benches: bUniProbe.
During hardware bring-up and firmware development, it is common to switch between different USB tools to test SPI, I²C, UART, or CAN devices, while also probing GPIO states or measuring analog signals. bUniProbe eliminates this fragmentation by combining protocol-level interaction with signal-level visibility into a single Wi-Fi connected platform.
Key Technical Capabilities:
-
Multi-Protocol: Support for SPI (controller/peripheral), I²C (controller/peripheral), UART, CAN, GPIO, ADC, and DAC.
-
Zero-Install Web UI: The device hosts its own web server, so you can monitor signals, send and receive data, and configure interfaces directly from your browser—no drivers or extra software required.
-
Hardware-Level Control: Dynamically switch between 3.3V and 5V logic levels, and enable/disable hardware pull-up and pull-down resistors on each GPIO across all interfaces.
-
Real-Time Monitoring & REST API: It features a built-in waveform viewer to debug timing issues on the fly, and provides REST APIs for all supported interfaces so you can fully automate hardware interactions.
bUniProbe is a completely open-source project, and both firmware and hardware files will be made available on GitHub.
We are currently in pre-launch on Crowd Supply. We would love for the Sparkfun community to check out the product and specs, and we welcome any feedback from fellow markers!

Feel free to ask me anything about the hardware design, routing, or capabilities in this thread!
