Zhihe A210 octa-core RISC-V SoC with 12 TOPS NPU powers SoM-based development board

Last year, we noted three upcoming high-performance RISC-V SoCs to watch out for: Zhihe A210, SpacemiT K3 , and UltraRISC UR-DP1000. The K3 has already been launched, and I’ll work on the K3-Pico-ITX SBC/mini PC review this coming weekend, while the UR-DP1000 is (still?) expected on the Milk-V Titan motherboard. However, we did not have that many details about the Zhihe A210 so far.

This has now changed since documentation has surfaced for the Zhihe A210 and a development kit (A210 SODIMM V2) based on a carrier board and a system-on-module itself powered by the octa-core RISC-V processor. Let’s have a look at both.
