Waveshare MK20 is a multifunctional macro keyboard with twenty mechanical keys featuring 0.85-inch LCD keycaps. As an upgrade to the earlier MK10 model, it adds a 2.8-inch secondary display along with two control knobs. The device supports AI voice interaction, real-time data display, and smart home integration with Home Assistant.
Like its predecessor, the MK20 relies on a dual-system architecture: an Allwinner T113-S3 dual-core Cortex-A7 processor runs Linux to drive the displays, and a GD32 microcontroller runs QMK for low-latency keyboard and knob input. Each LCD key offers 128×128 resolution and supports dynamic images, videos, and multi-layer overlays, while the 2.8-inch secondary display (428 × 142 resolution) provides status or customization information. The keyboard also includes two rotary encoders with aluminum caps for volume, playback, or timeline control. The device is built with an aluminum alloy top case and a 2.5D acrylic lens for durability.

Like the MK10, the MK20 also works with the ScreenKey software for Windows and macOS for theme management, macro customization, and real-time data display. With that, you can download, edit, and run visual themes that define the behavior of the 20 LCD keys and the 2.8-inch secondary display. On top of that, it works with LibreHardwareMonitor for system statistics (CPU, GPU, memory, temperature, etc.) and OpenWeather for weather data visualization.
The MK20 also supports XiaoZhi AI integration for voice recognition and AI-based automation, but it requires a network connection, which can be added via the external 2.4GHz USB WiFi adapter. Additionally, the device can connect with Home Assistant (HA) for smart home management via local token access or through the XiaoZhi MCP server, supporting integrations such as Xiaomi Miot Auto and Xiaomi Gateway 3. The MK20 operates in dual-system mode, allowing configuration via ScreenKey in Host Mode and independent macro execution with QMK firmware without the need for host software. More technical details and configuration instructions are available on the wiki.
The Waveshare MK20 macro keyboard is available on AliExpress for $169.23, on Amazon for $194.99, and on the official Waveshare store for $155.99. In the package, you will get the MK20 W (White) or B (Black) unit, a user manual, and a set of accessories such as two Type-A to Type-C cables, one USB Type-C dual-plug cable, an MK20 adjustable stand, a USB Wi-Fi adapter, and a USB Type-C power and signal splitter. An optional 5V/3A power adapter is also available.
