ETR232i is an embedded PC module with R1610C as the core and network data communication as the feature. It has a small size, rich onboard resources, and support for multiple applications.
The ETR232i is an embedded PC module built around an R1610C micro‑processor (96 MHz) and offers a range of communication interfaces, including 10/100 Mbps Ethernet, three serial ports, GPIO, and a simplified ISA bus. It is designed for applications such as communication management, industrial control, and GPRS/CDMA data terminals.
The document provides the module's technical specifications, pin‑out tables for the two 36‑pin IDC connectors (CN1 and CN2), and mechanical dimensions (74 mm × 53 mm). It also includes notes on power requirements, supported software tools, and optional high‑address‑line extensions. This manual is written in Chinese.
