There's no shortage of tools to test and debug hardware, but not many feature interfaces for SPI, I²C, UART, CAN, GPIO, ADC, and DAC in one device. bUniProbe is one of the few, and its hardware side is just half the story. It hosts its own web interface over Wi-Fi, so anyone on the network can open a browser, connect, and start working. This means multiple users can work together without the bother of installing software or drivers.
The web interface is tabbed by interface type, and the project’s crowdsupply campaign page shows a screenshot of the ADC tab, where each of the four channels displays a live voltage graph alongside a numerical readout. The I²C panel lets you set the peripheral address and bitrate, then read or write data directly from the browser. bUniProbe supports switching between 3.3V and 5V logic levels and pull-up or pull-down resistors on each GPIO pin.
The tool exposes a REST API across all its interfaces, allowing users to automate stuff or build custom tooling on top of it. bUniProbe is open source, with firmware and hardware files set to be published on GitHub once it ships.
