PCB files for the open and flexible security key - TKey

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.

- 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.

Mta1 usb dev: common questions

What microcontroller does the Mta1 usb dev use?

The Mta1 usb dev is built around the ICE40UP5K-SG48ITR, from the FPGA family.

How big is the Mta1 usb dev PCB?

The Mta1 usb dev measures 91.4 × 40.6 mm, has 4 copper layers and is 1.62 mm thick.

How many components are on the Mta1 usb dev?

83 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mta1 usb dev design files?

From the tillitis/tk1-pcba repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mta1 usb dev design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which tillitis chose for the repository.

Can I test firmware for the Mta1 usb dev without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
