README
README.mdTFUSBSERIAL01 - USB-C to serial converter with Pixhawk telemetry JST-GH connector
The converter is designed to service operations on UAVs. It respects the Pixhawk DS-009 connector standard.
Key features
- Could be connected to both peripheral or FMUs
- The FMU and peripheral connectors are separated, therefore there is no need for a special RX/TX cross-cable
- Could be used for sniffing serial communication on telemetry links between autopilot and its peripheral (Both connectors could be used at once)
- Supports hardware flow control
- The power delivered from USB is protected from excess current possibly drawn by peripheral or FMU
- The accidental power from FMU to USB is protected by reverse diode
Where to Get It?
TFUSBSERIAL can be bought directly from ThunderFly via email contact. The email can also be used if there are specific requirements for custom modifications and accessories (cables for example) or if the product will be inquired in significant quantities.

Questions
How big is the TFUSBSERIAL01 PCB?
It measures 30 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TFUSBSERIAL01 use?
39 parts, built around the FT231XQ-R, USBLC6-2SC6, SM06B-GHS-TB and SRL23. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TFUSBSERIAL01 KiCad files?
From the ThunderFly-aerospace/TFUSBSERIAL01 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/TFUSBSERIAL01.kicad_pcb and its schematic hw/sch_pcb/TFUSBSERIAL01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TFUSBSERIAL01 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
