Seeed’s Linux-friendly Gemini Lake SBC starts at $188

Feb 24, 2020 — by Eric Brown 7,596 views

Seeed’s “Odyssey – X86J41058x” SBC starts at $188 with 8GB RAM and runs Linux or Win 10 on a quad-core, 1.5GHz/2.5GHz Celeron J4105 with Raspberry Pi, Arduino/Grove, and 2x M.2 slots. Options include 64GB eMMC and an enclosure.

Seeed Studio has launched an Intel Gemini Lake based SBC it bills as the “most expandable Win10 Mini PC.” The nickname for the Odyssey – X86J41058x SBC stems from its optional Windows 10 Enterprise installation and activation, optional $14.90 enclosure, and extensive expansion options including Arduino/Grove and Raspberry Pi compatible headers. It also supports Linux.

The maker-like board is supported with a wiki, forums, tech support, and extensive documentation and tutorials, including instructions on how to install Arduino Core, OpenWrt, and Ubuntu. It does not, however, appear to ship with open hardware files such as schematics.

Three Odyssey – X86J41058x models are available, all featuring the quad-core, 1.5GHz/2.5GHz Celeron J4105 with 10W TDP from Intel’s Gemini Lake family, the more powerful successor to Apollo Lake:


  • Odyssey – X86J4105800 — 8GB RAM; $188
  • Odyssey – X86J4105864 — 8GB RAM; 64GB eMMC; Win 10 Ent. installed; $218
  • Odyssey – X86J4105864 — 8GB RAM; 64GB eMMC; Win 10 Ent. activated; $258

The Celeron J4105 is also used by Hardkernel’s open source Odroid-H2 SBC, which has the same 110 x 110mm dimensions as the Odyssey board, and which sells for $176 with 8GB DDR4 and 16GB eMMC. There’s also DFRobot’s maker-like, but not fully open LattePanda Delta, which instead uses the quad-core Celeron N4100 Gemini Lake SoC clocked at 1.1GHz/2.4GHz. Ibase’s commercial IB822 offers a choice of Gemini Lake chips up to a quad-core, 1.5GHz/2.8GHz Pentium Silver J5005.

Much of Gemini Lake’s performance improvement over the similarly 14nm Goldmont architecture Apollo Lake comes in the form of higher burst rates, which are based in part on the SoCs’ 4MB cache sizes, up from 1MB to 2MB for Apollo Lake. Video support has bumped up to 4K HEVC and VP9, and there’s a new Gen10 display controller.

The Odyssey – X86J41058 combines the Celeron with Microchip’s Cortex-M0+ based ATSAMD21G18 MCU for Arduino IDE support. There’s also a TPM 2.0 security chip.

In addition to the 8GB of LPDDR4 and optional 64GB eMMC, the SBC provides a microSD slot and a SATA III slot with 3x SATA power connectors. There are also SATA-compatible M.2 slots: a B-key slot that also supports USB 2.0 and an M-key with PCIe 2.0 x4. A SIM card slot is also provided.

Dual GbE ports, 802.11 a/b/g/n/ac, and Bluetooth 5.0 provide for further communications possibilities. For media, you get an HDMI 2.0a port and a USB 3.1 Type-C port with power and DP 1.2a support, both with up to 4096 x 2160 @ 60Hz resolution. There’s also an audio I/O jack.

In addition to the Type-C port, there’s a USB 3.1 host port and 2x additional USB host ports that are listed most frequently as 2.0 but are identified as 3.1 in the detail view. Low-power expansion is available via a 40-pin GPIO header compatible with Raspberry Pi HATs, as well as a 28-pin Arduino header that is compatible with Arduino shields and over 300 Seeed Grove modules and sensors.
