Sipeed M0sense is an AIOT development board based on BL702 of Bouffalo Lab, it's RISC-V architecture, and supports low-energy Bluetooth. There is an 8Pins FPC connector for connecting the LCD screen, 1 microphone, 1 RGB LED and a six-axis sensor chip on this board. One USB 2.0 FS routes to the Type-C interface.

Features

• Powerful chip support: Main chip BL702 RISC-V 144MHz
• Supporting edge machine learning: Developing Edge Computing and Machine Learning Capabilities with the TinyMaix Inference Framework
• Provide human-computer interaction: Onboard screen interface (Optional 0.68 inch 80x160 solution screen)
• Mass storage device: Thumb size but with 132KB RAM, 192KB ROM, 512KB Flash capacity
• Bluetooth wireless transmission: Support BlueTooth V5.0

Description

Sipeed M0Sense is a thumb-sized development board based on the BL702 chip focused on AIOT edge computing development. Although small in size, it can be considered a large capacity in terms of edge computing and machine learning. It will exceed your imagination that can play a powerful performance. The development board is able to run AI Models via & then unlock the amazing experience of AIOT edge computing, and support Drag&Drop Update Firmware too.

In addition, it can be used as a miniature machine learning module with a 0.68-inch 80x160 solution screen, 1 microphone, 1 RGB LED and a six-axis sensor chip. You can apply it to handwritten numeral recognition, keyword wake-up, gesture recognition, real-time people-flow counting and many more recognition detection items. With the microphone, you can make sound spectrogram analysis, human posture recognition using IMU, etc. It is a great option for machine learning aspects.
