Overview
MillerV1 is an open-source printed circuit board by Flynsky, from the Flynsky/MillerProject repository on GitHub. It is a 4-layer board of 120 × 80 mm with 284 parts on 278 nets, routed with 9,760 tracks and 1,399 vias.
It is built around the B340 and DSHP04TS-S. Its parts include 131 capacitors, 73 resistors, 14 ICs, 7 inductors and 3 diodes. It belongs with the RP2040 boards of this library.
Main components
2README
README.mdThis design is a TOP SECRET Miller Project.
Arbeits Aufteilung:
- Ibex-Port (Handl)
- PCB, Schematic + Layout (Gewiese)
- USB PHY, ISO7816 Interface / Card VCC-Switching, Power Domains (Belm)
- Pin Assignment, Constraints, Bringup-Testinfrastruktur - Bindeglied zwischen Hardware und HDL (Drüen)
ToDo Redesign:
- USB-Phy reindesignen (voraussichtlich TUSB1106)
- zusätzlicher USB-Connector für Device-Mode-USB und Routing zum TUSB1106. Also Referenzimplementierung kann hier das Sonata-Board (lowRISC) dienen
- ISO7816-Interface: Das sind nur FPGA-Pins die an PIN-Header geroutet werden. Ggf. noch Level-Shifter
- Alles raus was wir nicht brauchen
- Bissl hübscher machen

Questions
How big is the MillerV1 PCB?
It measures 120 × 80 mm and has 4 copper layers, 1.58 mm thick.
What parts does the MillerV1 use?
284 parts, built around the B340 and DSHP04TS-S. 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 MillerV1 KiCad files?
From the Flynsky/MillerProject repository on GitHub, at the commit this page was made from: the board is hardware/MillerV1/MillerV1.kicad_pcb and its schematic hardware/MillerV1/MillerV1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MillerV1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Flynsky before reusing the design.
