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 a feather development board form factor for greater simplicity and rapid project development assistance.

ST provides STM32Cube.AI, 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.

Wio Lite AI single board has an 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 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 one SWDIO port are 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 to a vision project out-of-box. There is a 12-pin audio slot for Audio expansion.
