## Description

The Milk-V Pioneer is one of the most powerful RISC-V development platforms available, featuring the SOPHON SG2042 SoC with 64 C920 RISC-V cores running at up to 2GHz. Built in the standard mATX motherboard form factor, it provides a native RISC-V development environment with desktop-class performance.\n\nThe Pioneer supports up to 128GB DDR4 3200MHz ECC RAM across four DIMM slots, with extensive storage options including PCIe 4.0 x16 for high-performance GPUs, dual M.2 NVMe slots, five SATA 6Gbps ports, and eMMC. Networking is handled by dual 2.5GbE ports with optional Intel X540-T2 10GbE expansion.\n\nWith 8x USB 3.0 ports, standard ATX power input (120W typical), and compatibility with standard PC cases and components, the Pioneer enables developers to build complete RISC-V workstations and servers. The Pioneer Box variant comes pre-configured with 128GB RAM, 1TB PCIe SSD, AMD R5 230 GPU, and 350W PSU. It's the first choice for teams needing to compile and test software natively on RISC-V.
