Breakout tt06-qfn is an open-source printed circuit board by htfab, from the htfab/breakout-pcb-snapshot repository on GitHub, published under the Apache-2.0 licence. It is a 2-layer board of 50 × 52 mm with 153 parts on 65 nets, routed with 789 tracks and 145 vias.
It is built around the 24LC02BT-I/MC, RSP-122811-01 and NPTC202KFMS-RC. Its parts include 19 capacitors, 15 connectors, 6 resistors and 2 ICs. It belongs with the interfaces and adapters boards of this library.
The Tiny Tapeout chips are delivered on a breakout board that allows:
the demo board to host and interact with the IC and its projects
easily moving the ASIC to other more specialized PCBs
The PCBs are keyed such that direction of insertion onto hosts is made clear.
The breakout-tt03-qfn directory holds a QFN breakout suitable for TT02 and TT03 chips.

It provides access to the project inputs, outputs, select pins etc, though the naming on the PCB refers to the caravel mprj_io pin numbers.
The pin headers used up to this point have been dual entry (access from both top and bottom).
The breakout-tt04-qfn directory holds a QFN breakout suitable for TT04 chips. To date, we've been using it with the TT03p5 trial run (hence the markings), though the pinout remains constant for TT04.

We've now moved to more easily sourced standard 100 mil pin headers, placed on the bottom of the PCB. Markings on top are Tiny Tapeout names of the pins (in0 is input 0, ot5 is output 5, etc).
Following the same footprints as the breakout boards, the ASIC simulation PCBs are circuits designed to allow for use of demo or custom boards while developing or awaiting the actual chips. A version was already produced for TT03 and a TT04-compatible version, with the extra I/O and dedicated clock/reset pins, is under development.

153 parts, built around the 24LC02BT-I/MC, RSP-122811-01 and NPTC202KFMS-RC. 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.
From the htfab/breakout-pcb-snapshot repository on GitHub, at the commit this page was made from: the board is breakout-tt06-qfn/breakout-tt06-qfn.kicad_pcb and its schematic ASIC-simulator/tt03-fpga-ICE40UP5k/caravel-breakout-fpga-ICE40UP5K-TT3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
