Phased out Raspberry PI CM4 quad SATA provider board turns into open-source {hardware}

Wiretrustee carrier board for Raspberry Pi CM4 was unveiled about one 12 months in the past with 4 SATA connectors to assist individuals construct their very own 4-bay NAS. Sadly, the corporate determined to discontinue the undertaking as a result of semiconductors market state of affairs.

The excellent news is the board is now open-source {hardware} with all resources shared publicly together with the Allegro schematics and PCB format, Gerber information, 3D fashions for the heatsink, and case designs for two.5-inch or 3.5-inch drives. All information can be found below “CERN Open {Hardware} Licence Model 2 – Permissive”.

Wiretrustee open-source hardwareRight here’s a fast reminder concerning the Wiretrustee board specs:

  • Supported SoM – Raspberry Pi Compute Module 4 and 4 Lite
  • Storage
    • 4x SATA 2.0 through Marvell 88SE9215 (PCIe 2.0 x1 to 4 6Gb/s SATA ports, no HW RAID)
    • MicroSD card slot
  • Video Output – HDMI 2.0 as much as 4Kp60
  • Networking – 1x Gigabit Ethernet port
  • USB – 2x USB 2.0 ports
  • Misc – 4-pin fan, RTC + battery, exterior management board linked through FPC cable with extra LEDs, reset, and energy buttons.
  • Energy Provide – 5V through USB-C port as much as 5A max, or 12V/5A through 4-pin header
  • Dimensions – 100×100 mm

Whereas in concept, you might construct your individual, the undertaking was phased out due to provide points, I’d assume largely due to the dearth of provide for Raspberry Pi CM4 modules, however probably though due to Marvell 88SE9215 (TBC), which means the board may need to be modified with a brand new PCIe to SATA chip except possibly you intend to fabricate the board 2023… There are pin-to-pin options to Raspberry Pi CM4 like Radxa CM3 or Pine64 SoQuartz, however I don’t suppose the software program is there simply but.

[Update: I got confirm about the Marvell chip shortage:

In Jan 2021, when we were building the first prototype, 88SE9215 was around $8 a piece. In April, when I started CrowdSupply campaign prep and calculation my supplier reported it was ~$50-$60 a piece.


As a aspect notice, Wiretrustee continues to be working however is specializing in a totally completely different undertaking: an open-source peer-to-peer Wireguard-based VPN undertaking designed to “make it straightforward to create safe personal networks on your group or house”. If , you’ll additionally discover it on Github.
