The Bit-Brick K1 Pro is a new single-board computer (SBC) that’s positioning itself as a serious Raspberry Pi 5 alternative—especially for users who want faster storage, flexible expansion, and built-in AI acceleration. Instead of being limited to basic maker projects like simple sensor and actuator setups, this compact board is designed to handle heavier tasks thanks to a broad set of ports and upgrade options.
One of the biggest highlights is storage and expansion. The Bit-Brick K1 Pro includes multiple M.2 slots: two M.2 Key-M slots plus one M.2 Key-E slot. That means you can install up to two M.2 2280 NVMe SSDs for high-speed storage, and also add an M.2 WiFi card if you want wireless connectivity. Out of the box, though, it does not include built-in WiFi or Bluetooth, so anyone who needs wireless should plan on adding a module. For reliable wired networking, it also comes with Gigabit Ethernet.
For display output, the K1 Pro supports HDMI 2.1 with 4K at up to 120Hz, which is a strong feature for a board in this category—useful for smooth UI, digital signage, and high-refresh 4K setups. It also includes MIPI-DSI for certain compact displays commonly used in the maker ecosystem. Camera projects are covered too, thanks to a MIPI-CSI interface that can be used with compatible camera modules.
Performance is driven by the integrated RK3576 system-on-chip, featuring eight Cortex-A72 CPU cores. A key selling point is the onboard NPU rated at 6 TOPS (INT8), which can help with local AI workloads such as image analysis and other edge AI applications—reducing the need to rely on cloud processing for certain tasks.
Memory and onboard storage options are also straightforward: LPDDR4X RAM is offered in 4GB and 8GB configurations, while eMMC storage ranges from 32GB to 64GB. For additional devices and peripherals, the board provides USB 3.0 for faster external storage and USB 2.0 for accessories like keyboards, mice, and other input hardware. Power is delivered over USB-C, keeping the setup simple.
Like many SBCs aimed at makers and embedded projects, the K1 Pro also includes a 40-pin GPIO header for hardware interfacing. Another notable detail is its wide operating temperature range, rated for environments from -40° to 185°F, which may appeal to industrial, workshop, and outdoor deployments where typical consumer electronics can struggle.
As for pricing and availability, the Bit-Brick K1 Pro is listed on AliExpress starting at around $160. Depending on where you live, shipping costs and import fees may increase the final price. It’s also worth keeping in mind that warranty support can be inconsistent with some international marketplaces, so buyers may want to factor that risk into their decision.
Overall, the Bit-Brick K1 Pro stands out as a feature-rich Raspberry Pi 5-style SBC for users who care about NVMe expandability, 4K 120Hz output, camera support, GPIO flexibility, and on-device AI acceleration—making it a compelling option for advanced DIY builds, edge computing, and compact AI projects.
