Document the compatible string for the MusePi Pro [1]. It is a 1.8-inch
single board computer based on the SpacemiT K1/M1 RISC-V SoC [2].
Here's a refined list of its core features for consideration:
- SoC: SpacemiT M1/K1, 8-core 64-bit RISC-V with 2.0 TOPS AI power.
This suggests potential for light AI/ML workloads on-device.
- Memory: LPDDR4X @ 2400MT/s, available in 8GB & 16GB options.
Sufficient for various workloads.
- Storage: Onboard eMMC 5.1 (64GB/128GB options). M.2 M-Key for NVMe
SSD (2230 size), and a microSD slot (UHS-II) for expansion.
Good variety for boot and data.
- Display: HDMI 1.4 (1080P@60Hz) and 2-lane MIPI DSI FPC (1080P@60Hz).
Standard display options.
- Connectivity: Onboard Wi-Fi 6 & Bluetooth 5.2. A single Gigabit
Ethernet port (RJ45). Given the stated markets,
this should cover basic networking.
- USB: 4x USB 3.0 Type-A (host) and 1x USB 2.0 Type-C (device/OTG).
Decent host capabilities.
- Expansion: Full-size miniPCIe slot for assorted modules
(4G/5G, wireless etc.). A second M.2 M-Key (2230) for more
general PCIe devices (SSD, PCIe-to-SATA, comm boards).
- GPIO: Standard 40-pin GPIO interface, as expected for an SBC.
- MIPI: Includes 1x 4-lane MIPI CSI FPC and 2x MIPI DSI FPC interfaces
for cameras and displays.
- Clock: Onboard RTC with battery support.
