Sipeed Lichee Pi 4A Single Board Computer

Sipeed Lichee Pi 4A Development Board Risc-V TH1520 Linux SBC   1. Introduction LicheePi 4A is the high performance RISC-V linux development board using Lichee Module 4A, based on TH1520 SOC (4xC910@1.85G, RV64GCV, 4TOPS@int8 NPU, 50GFLOP GPU), LicheePi 4A contains maximum 16GB 64bit LPDDR4X, 128GB eMMC, supports HDMI+MIPI dual 4K display, supports 4K camera input, dual Gigabit Ethernet interfaces (one of these supports POE) amd 4 USB3.0 interfaces, supports kinds of audio processing by C906 core. The LicheePi 4A is the most powerful RISC-V SBC as of now (Q2 2023). Its performance is about 2 times that of the previous generation RISC-V SBC VisionFive2. Without enabled custom instruction set acceleration, its performance is close to the Raspberry Pi 4 based on ARM A72. With acceleration enabled, it can match the Raspberry Pi 4. It also has a maximum 16GB ultra-large memory, twice that of the Raspberry Pi 4's max 8GB! The LicheePi 4A can be used as a typical RISC-V verification pla
