Fanless industrial mini PC with Ryzen R2314

The Partaker B4 is a passively cooled barebone built around the AMD Ryzen Embedded R2314 quad-core processor running at 2.1 GHz base and 3.5 GHz turbo. It ships with 16 GB of DDR4 memory and a 256 GB SSD installed. The aluminium chassis enables silent 24/7 operation in dusty or hot environments from -20°C to +60°C with an industrial drive. Dual HDMI 2.0 ports drive independent 4K displays at 60 Hz for signage or HMI use.

Serial and network connectivity limits

Six COM ports provide four RS232 and two RS485 links for PLCs, sensors and legacy equipment. Two RTL8111H Gigabit Ethernet ports top out at 1000 Mbit/s each. Dual 4K output is capped at 4096×2160 @ 60 Hz over HDMI 2.0. Expansion relies on one Mini PCIe slot for mSATA, one M.2 2230 E-key for Wi-Fi 5 or Wi-Fi 6 plus Bluetooth, and one M.2 3052 B-key with SIM slot for 4G or 5G modules. GPIO requires a separate order.

Power and mounting checks before ordering

The unit accepts DC 12 V to 24 V input, so verify your supply or vehicle voltage matches that range. Confirm the 186 × 140 × 66 mm footprint fits your DIN-rail, VESA or wall-mount plan. Ensure any wireless or cellular module you add matches the M.2 2230 E-key or 3052 B-key pinouts. The pre-installed 2.5-inch drive bay and mSATA slot set the storage form factors you can use.

Questions about this item

Should I pick the 16 GB DDR4 2400 MHz configuration or add more memory up to the 64 GB limit?

The unit ships with 16 GB in two SODIMM slots. You can expand to 64 GB total by populating both slots with higher-capacity DDR4 2400 MHz modules if your workloads need more headroom.

What does the Ryzen R2314 2.1 GHz base and 3.5 GHz turbo actually deliver in daily use?

The quad-core Zen+ processor runs at 2.1 GHz base and boosts to 3.5 GHz, giving responsive performance for industrial automation, edge computing and dual 4K display output without active cooling.

How do the two RTL8111H Gigabit Ethernet ports and HDMI 2.0 outputs limit real-world throughput?

Each RJ45 port caps at 1 Gbps, so aggregated throughput tops out at 2 Gbps. Both HDMI 2.0 ports support 4096 x 2160 at 60 Hz, enabling two independent 4K displays simultaneously.
