The Bit-Brick K1 is a powerful RISC-V single-board computer (SBC) designed for AI, industrial automation, and edge computing. Built around the SpacemiT Key Stone K1 processor, it features an ultra-low-power octa-core RISC-V SoC with 2.0TOPS AI acceleration, making it an ideal platform for machine learning, robotics, and IoT applications.
At the heart of the Bit-Brick K1 is the SpacemiT X60 processor, which adopts an octa-core dual-cluster architecture for efficient workload distribution.
- Cluster 0: Four cores with 32K L1 cache, 512K L2 cache, 512KB TCM, and built-in AI acceleration.
- Cluster 1: Four additional cores with 32K L1 cache and 512K L2 cache for optimized multi-threading and computational efficiency.
The processor integrates 256-bit vector extensions to enhance AI and signal processing capabilities, making it a robust choice for demanding industrial applications.
The IMG BXE-2-32 GPU, running at 819MHz, supports OpenCL 3.0, OpenGL ES 3.2, and Vulkan 1.3, ensuring smooth graphics performance. Additionally, the SBC offers 4K H.265 and H.264 encoding/decoding, making it a strong contender for AI-driven vision processing and edge computing tasks.
The Bit-Brick K1 comes with a range of high-speed interfaces, including:
- USB 3.0, USB 2.0 Host, and USB 2.0 OTG for versatile peripheral connections.
- Gigabit Ethernet for high-speed networking.
- MIPI CSI and MIPI DSI for camera and display integration.
- PCIe 2.0 x2 to enable high-speed data transfer.
- Three M.2 slots for flexible expansion: - SLOT 1 & SLOT 2: M.2 Key-M for 2280 NVMe SSDs. - SLOT 0: M.2 Key-E for wireless modules (without USB/PCIe support).
Industrial-Grade I/O and Interface Options
With 40 GPIOs and multiple SPI, I2C, UART, PWM, and CAN interfaces, the Bit-Brick K1 is well-suited for embedded systems, industrial automation, and AI-powered IoT solutions.
