Notes
- The measurement of node's input current is on the CM4 Card (tps2420 efuse current monitor output)
- I tried to use GPIO pin straps to set up USB Hub, but there is no such configuration that works, so I end up placing an I2C EEPROM that contains the settings. There are three jumpers at the back of the board that connect that EEPROM to RPI & hold the reset of USB HUB, so you can/need to flash the EEPROM image the first time.
- Also note that because reversing the polarity of USB data eases the layout, all of the device's USB polarity is swapped and configured as such, so that is why in the sch the P/N is reversed.
- There might be some issue with the LED indicator on the USB Hub.
- You could connect the MII interface to RPI, but I'm not sure how to use it to turn it into a managed switch.
- And just to remind you that the M.2 connector on this board is a non-standard pinout, please don't attach anything other than the CM4 Card.

Questions
How big is the CM4ClusterHat PCB?
It measures 87.3 × 56.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CM4ClusterHat use?
240 parts, built around the RP2040, W25Q128JVSIQ, D3V3F4U10LP-7(ES) and 24LC08B/P. 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 CM4ClusterHat KiCad files?
From the will127534/Miniature-CM4-Cluster repository on GitHub, at the commit this page was made from: the board is ClusterHat/CM4ClusterHat.kicad_pcb and its schematic CM4Card/CM4Card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CM4ClusterHat design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
