MAIX-II Core Module
Following the classic K210 MAIX-I series AIOT boards, Sipeed continues to launch a variety of edge computing boards that can run a complete Linux environment, which will be named after MAIX-II and MAIX-III in turn.
The MAIX-II core module is an entry-level edge computing (built-in NPU) board that can run in a Linux environment. It uses a fast-pluggable NGFF 67pin gold finger design and is equipped with Allwinner V831 SoC.

MAIX-Linux Software Features
MAIX-II (V831) is an iterative version of MAIX-I (K210), it has a higher CPU frequency, larger memory, and more complete peripheral support.With Sipeed's MAIX-LINUX firmware (based on OpenWRT) adapted for edge computing, users can enjoy a more complete development environment and abundant software resources under LINUX.Sipeed provides opkg package source for MAIX-Linux, integrates python3.8.5 environment by default, and brings unique maix npu acceleration package, making AIOT project design and development easier.In order to conform to the traditional AI developer's usage habits, Sipeed adapts the Jupyter Notebook development environment for MAIX-II, making it easier to run python code
