Description

WL0F00088000BGXAANA00 is an 8.8-inch bar-type STM32 development board powered by the STM32N657 MCU. Featuring the Neural-ART NPU with AI acceleration of up to 600 GOPS at 1 GHz, the board is designed for edge AI vision and embedded system development. It supports on-device AI inference, enabling visual data processing without relying on a cloud connection.

The development board integrates an 8.8-inch IPS TFT LCD with a 1920x480 resolution, 85/85/85/85-degree wide viewing angles, and a projected capacitive touch panel (PCAP). Its bar-type display format is suitable for space-constrained applications such as smart home appliances, off-highway vehicle dashboards, and narrow industrial control panels.

Designed for edge AI vision development, the board provides MIPI CSI-2 and parallel camera interfaces for camera connectivity. When paired with the B-CAMS-IMX camera unit, the platform can perform on-device visual recognition and AI inference for applications such as anomaly detection, object recognition, and human detection.

WL0F00088000BGXAANA00 provides multiple communication interfaces, including CAN FD, RS485, RS232, Ethernet, USB-C, UART, SPI, I2C, and GPIO. It also features 32 MB RAM, 64 MB external Flash memory, a 9V to 36V wide input voltage range, and support for ST TouchGFX. The board operates from -20℃ to +70℃ and can be stored from -30℃ to +80℃.

As an ST Authorized Partner, WINSTAR develops display and embedded hardware solutions based on the STM32 ecosystem. This development board combines STM32N657 processing, AI acceleration, camera connectivity, and a bar-type touch display in a single development platform for edge AI vision and embedded system development.

Note: Reliability testing is currently in progress, and product samples are under preparation. Sample availability is expected in approximately 2 to 3 months.
