README
prototypes/mta1-usb-dev/README.mdmta1-usb-dev
This is the original TKey design, intended as a development platform. It is a larger PCB, that connects to a PC via a USB C cable.
Main features:
-
2 ICE40 FPGAs.
-
The first ICE40 (Interface FPGA) is connected to a USB C plug, and is loaded with a gateware that contains a soft USB device. This gateware acts as an USB-to-GPIO interface to the second ICE40.
-
The second ICE40 (application FPGA) is loaded with a RISC-V soft core containing the security firmware. User applications are run on this gateware.
-
The second ICE40 also has an input button for user presenence detection.
-
An FTDI module is included for programming both the Application and Interface FPGAs.
-
Both ICE40s can be configured to boot from included SPI flash memories, NVCM, or be live programmed from the FTDI module.
-
All GPIO lines between the two FPGAs, as well as all programming signals, are exposed on 0.1" headers for probing.

Questions
How big is the Mta1 usb dev PCB?
It measures 91.4 × 40.6 mm and has 4 copper layers, 1.62 mm thick.
What parts does the Mta1 usb dev use?
92 parts, built around the ICE40UP5K-SG48ITR50, FT2232H MINI MODULE, W25Q80DVSNIG and MC2016Z48.0000C19XSH. 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 Mta1 usb dev KiCad files?
From the tillitis/tk1-pcba repository on GitHub, at the commit this page was made from: the board is prototypes/mta1-usb-dev/mta1_usb_dev.kicad_pcb and its schematic hw/application_fpga.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mta1 usb dev design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
