Arduino Bug Hopper USB-to-UART Debugging Board

Built around the FT230XQ-R FTDI USB-to-UART bridge, Arduino BugHopper provides a reliable, high-speed serial link between your development machine and the UNO Q or VENTUNO Q, enabling advanced debugging and logging without occupying your main I/O.

Its compact 38.5 × 11 mm footprint makes it easy to integrate into any workspace or enclosure: a USB-C connector enables direct cable attachment, and a male 1.27 mm 2x5 header can be used for compact ribbon cable setups. In addition, onboard LEDs clearly indicate the status of 5 V, 3.3 V, and VTARGET power rails at a glance.

Whether you’re developing locally or managing a remote system, BugHopper simplifies debug and Linux console access and helps you keep your UNO Q projects running smoothly.

Key benefits

• Dedicated debugging without sacrificing I/Os: The USB-to-UART connection preserves your UNO Q main I/Os for sensors, actuators, and other peripherals.
• Plug-and-play connectivity: Works seamlessly with standard FTDI drivers and terminal software for immediate debugging, logging, and firmware flashing.
• Compact and integration-friendly: Small footprint fits benchtop setups, tight enclosures, or permanent installations without adding bulk.
• USB-C connection: Standard connector ensures compatibility with multiple development machines.
• Visual status at a glance: Onboard LEDs indicate power rail status for instant troubleshooting.

Application examples to explore

• Remote debugging and diagnostics: Monitor serial output from deployed devices in the field, debug headless systems without physical access, or maintain UART logging connections to boards installed in enclosures, racks, or remote locations where direct USB access isn’t practical.
• Firmware development and flashing: Flash firmware updates via serial bootloaders, monitor real-time debug output during code execution, capture boot sequences and initialization logs, or maintain persistent UART connections during iterative development cycles without disrupting other I/O.
• Automated testing and validation: Build continuous integration test rigs that log serial output for analysis, create automated firmware flashing stations for production or QA workflows, monitor device behavior during extended stress testing, or capture diagnostic data from multiple boards simultaneously in parallel test benches.
• Educational labs and coursework: Teach UART communication fundamentals with hands-on serial debugging exercises, demonstrate embedded systems troubleshooting workflows using real hardware, provide students with affordable debugging tools for individual projects, or create durable lab setups that withstand repeated classroom use across multiple semesters.
• Field service and support: Diagnose hardware deployed remotely via UART Linux console access, retrieve error logs from installed systems without full disassembly, perform firmware updates on fielded devices through serial interfaces, or troubleshoot communication issues between embedded modules in production equipment.
