README
README.mdPLUTO JTAG ADAPTER
JTAG programmer for the PLUTOSDR evaluation kit from ADI.
Features
- JTAG pins breakout from 1.28mm headers to 2.54 standard header pins for use with platform cable II or other external JTAG
- Integrated FT2232 USB to sync serial controller, to serve as a JTAG + UART host (Still work in progress)
Known issues:
v1.0.0
- VREGOUT and VREGIN should be floating but connected to 1.8V
- VPHY and VPLL connected to 1.8V supply, should be connected to 3.3V through ferrite bead
- FT2232 chip not working due to previously stated issues

Questions
How big is the Pluto jtag adapter PCB?
It measures 53 × 34.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pluto jtag adapter use?
64 parts, built around the 93LC46B/P, AP2112K-1.8, AP2112K-3.3 and FT2232HL. 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 Pluto jtag adapter KiCad files?
From the teodor961/pluto_jtag_adapter repository on GitHub, at the commit this page was made from: the board is pluto_jtag_adapter/pluto_jtag_adapter.kicad_pcb and its schematic pluto_jtag_adapter/pluto_jtag_adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pluto jtag adapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask teodor961 before reusing the design.
