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 platform. Its powerful performance allows faster native compilation without the need for QEMU emulation.

    We will soon (Q2 2023) release the LicheeCluster 4A based on the LM4A for cluster computing, supporting up to 7xLM4A for cluster build and compilation, ideal for distribution build farms. Stay tuned!

    While maintaining high performance, we have also done our best to design for cost. The 8GB RAM version is priced at ¥749 - 899 (100130), while the 16GB version is ¥1100-1300 (155185). This is a better price/performance ratio than the Raspberry Pi 4 8GB (~$150)!

    Whether you are a RISC-V enthusiast or not, the LicheePi 4A is a game-changing high-performance RISC-V SBC worth getting!
