Sipeed M1/M1W AIoT Module
The Sipeed M1/M1W is an AIoT (Artificial Intelligence of Things) module built around the Canaan Kendryte K210 edge AI processor based on the RISC-V architecture. The K210 integrates a 64-bit dual-core high-performance, low-power processor, with each core featuring a Floating Point Unit (FPU) for efficient mathematical computations.
The processor also includes a Convolutional Neural Network Processor (KPU) for AI acceleration, a Fast Fourier Transform (FFT) accelerator for signal processing, and a Field Programmable IO Array (FPIOA) that enables flexible peripheral configuration. The module supports a variety of mainstream AI development frameworks, making it suitable for computer vision, machine learning, and edge AI applications.
The M1W version features an onboard ESP8285 Wi-Fi chip supporting the IEEE 802.11 b/g/n wireless standard, enabling seamless wireless networking and IoT connectivity.

3. M1/M1W Specifications
The M1/M1W AI module consists of four major components:
- 3-channel DC-DC power supply
- 16MB Flash memory
- Kendryte K210 AI processor
- ESP8285 Wi-Fi module (M1W only)
The K210 serves as the core processing unit and includes 8MB of on-chip SRAM. It delivers exceptional AI performance for both computer vision and audio processing applications with a computing capability of up to 1 TOPS. Integrated hardware accelerators such as the KPU, FPU, FFT, and Audio Processing Unit (APU) enable efficient implementation of machine vision, speech recognition, audio preprocessing, and AI inference.
The M1W further enhances functionality with built-in Wi-Fi for wireless communication and cloud connectivity.

M1 vs. M1W
To support a wider range of embedded AI applications, Sipeed offers both M1 and M1W modules.
- M1W includes an onboard ESP8285 Wi-Fi module for wireless networking.
- M1 does not include Wi-Fi but offers the same AI processing capabilities.
Both modules share the same hardware architecture, software environment, and AI performance. The only functional difference is the integrated Wi-Fi capability available on the M1W.
