Marvell 7040 based networking SBC includes 10GbE, 5G and WiFi 6 port






On Kickstarter: Globalscale’s $ 159 “Mochabin” SBC runs Linux on a -A72 Marvell 7040 quad with up to 8 GB of DDR4, 10 GbE and 1 GbE SFP, 4x GbE, WAN / PoE, 2x M.2 and a housing. A $ 199 model adds WiFi 6.

Globalscale Technologies has announced a more powerful follow-up to its EspressoBin network card. The Mochabin upgrades to a 1.4GHz quad-core Cortex-A72 Marvell Armada 7040, compared to the previous quad -A53 Armada 3720, and offers more Ethernet ports, including a 10GbE port. The card driven by Ubuntu or OpenWrt is supported by the same EspressoBin.net and supports a variety of firewall, networking, SDWAN and NAS applications.

We saw the Marvell 7040 earlier this year on the IEI DRPC-330-A7K DIN rail computer. The 7040 has the same quad-core Cortex-A72 CPU block as the Armada 8040, which we saw on SolidRun’s Marvell MacchiatoBIN boards and later ClearFog CX 8K. However, the cores are clocked at 1.4GHz instead of 2.0GHz, and the 7040 has fewer PCIe Gen3, 2.5GbE, and 10GbE interfaces. There’s no GPU on any of these headless network SoCs, but you do get networking acceleration, including a packet processor with a security coprocessor.

Globalscale, which we last saw in 2019 with its Armada 3720-based Sheeva64 reboot of its SheevaPlug NAS mini-PC, successfully launched the Mochabin on Kickstarter. The base package starts at $ 159, including 4GB of DDR4, 16GB of eMMC, a 12V power supply, and a plastic case. A $ 199 package adds a mini-PCIe card with a NXP 88W8098 SoC with simultaneous dual-mode WiFi 6 (AKA Wi-Fi 6 and 802.11ax) plus Bluetooth 5.0.

A $ 225 package that also ships in May 2022, adds an open source Linux stack provided by Sartura, allowing additional functionality of CPE and router. In July, Sartura, which also supports EspressoBin, announced an agreement with IEI to provide embedded Linux support. The Sartura stack, which replaces the standard Ubuntu offering, is based on OpenWrt and core Linux. The software includes Replica.a, an open source build system based on Gentoo Linux.

A $ 450 NAS package offers a 2TB hard drive with 1TB usable storage with options for storage up to 6TB. The package also includes the Cubbit distributed NAS platform instead of Ubuntu or from OpenWrt / Sartura. Cubit offers a peer-to-peer swarm network that promises complete privacy by using customer computers for storage instead of cloud servers. Cubbit uses EspressoBin as the heart of its sound Cubbit cell NAS device.

Finally, there is a $ 549 package with Ubuntu, power supply, case, and WiFi 6 which also adds a sub-6 GHz 5G module and 4x antennas. The package is shipped in June. Mochabin also supports Yocto and Arch Linux.

The Mochabin provides 4 GB or 8 GB of DDR4, with optional soldering. For storage, the SBC provides 16 GB eMMC, SATA interface and M.2 slot with SATA support.

A second M.2 with support up to 5G comes with a SIM card slot. A mini-PCIe slot supports the optional WiFi 6 modem. The spec list on Globalscale’s website also mentions PCIe 3.0 in addition to M.2 and mini-PCIe slots, but that likely refers to M.2 slots rather than an additional interface.

As noted by CNXSoft post that alerted us to the products, some specs are confusing. An example is that the standard specification list shows 10 GbE with SFP + and 1 GbE with SFP. However, the $ 225 OpenWrt / Sartura package would add SFP + technology. You also get a PHY and a Marvell Gigabit switch, as well as 4 standard GbE ports and a WAN port that offers PoE input.

The Mochabin is further equipped with 2x USB 3.0, a micro-USB console port and a MikroBus expansion connector for Click modules. You also get CPU start and select switches, a fan header, LEDs, and a 10-pin JTAG, and the pictures indicate a coin-cell battery, presumably for an RTC.

More information

The Mochabin is available on Kickstarter until November 14 starting at $ 159, with shipments starting in May or June 2022, depending on the package. Shipping is $ 20 in the US and $ 30 elsewhere. More information can be found on the Home Page and Mochabin’s Global Page.
