Description

Wio Lite AI is a microcontroller vision development tool based on the STM32H725AE chip which is a Cortex®-M7 32-bit 550 MHz high-performance microprocessor. It is designed in feather development board form factor for greater simplicity and rapid project development assistance.

For project development, both ST and Seeed Studio offer software support for quick start of Wio Lite AI for vision project.

ST provide ，the industry’s most advanced toolkit capable of interoperating with popular deep learning libraries to convert any artificial neural network for Wio Lite AI to run optimized inferences.

Seeed will provide an Arduino development environment for Wio lite AI to reduce your learning costs and can help beginners to quickly learn microcontroller machine vision and apply it to real production environments.

Also, Wio Lite AI single board has 8M PSRAM Memory controller for multitasking performance, 16MB SPI NOR flash for the operating system as well as a micro-SD card slot for extra storage. It also has wireless connectivity with a dual-band 2.4GHz/5GHz WiFi and Bluetooth 5.1.

Wio Lite AI Single Board has STMH725AE I/O for expansion, the I/O level of the board is 3.3V. There are 6 analog pins and 14 digital pins, also, one UART, one I2C, one SPI, one CAN and SWDIO port is available. You can power the board with 5V USB Type-C.Wio Lite AI is shipped with a 2-million-pixel DCMI camera and a 2.8-inch resistive touch screen RGB LCD, which makes it easy to apply into a vision project out-of-box. Also, there is a 12-pin audio slot for Audio expansion.
