## Description

## Overview

The Muse Pi Pro is one of the most capable RISC-V single-board computers available, built around the SpacemiT M1 (K1) SoC — an octa-core 64-bit RISC-V processor running at 1.8GHz with a 2 TOPS NPU and an Imagination IMG BXE-2-32 GPU supporting Vulkan 1.2, OpenGL ES 3.2, and OpenCL 3.0. It fits the standard Raspberry Pi 4 footprint (85×56mm), making it a drop-in form factor replacement for RPi-compatible enclosures.

Connectivity is unusually comprehensive for a RISC-V board at this price: Gigabit Ethernet, onboard WiFi 6 + Bluetooth 5.3, four USB 3.0 ports, HDMI output, and both an M.2 M-Key 2230 socket (NVMe or wireless) and a mini PCIe socket (WiFi or 4G LTE/5G modules). RAM options are 8GB or 16GB LPDDR4X, with 64GB or 128GB eMMC flash. A standard 40-pin GPIO header enables HAT compatibility.

The K1 SoC targets edge AI inference with its 2 TOPS NPU (INT8), and supports 1080p60 H.265/H.264 hardware video decode and encode. Two MIPI CSI interfaces and one MIPI DSI port extend it to camera and embedded display use cases.

Armbian, Bianbu OS (SpacemiT's own Ubuntu derivative), Debian, and Ubuntu are supported. The Muse Pi Pro is a compelling choice for RISC-V software development, AI inference experimentation, and anyone looking to move workloads off ARM/x86 onto open ISA hardware.
