Applications
The RN1810E-I/RM110 is used in industrial IoT gateways, embedded telemetry nodes, and smart-building controllers that require Wi-Fi connectivity without the complexity of running a full TCP/IP stack on the host microcontroller. It also serves automotive telematics and fleet-monitoring devices where the TS 16949 screening level satisfies quality system requirements. Engineers integrate it via a simple UART ASCII command set, reducing firmware development time for cloud-connected sensor and control applications.

Frequently Asked Questions
How does RN1810E-I/RM110 allow a resource-constrained MCU to connect to a Wi-Fi network without a TCP/IP stack?
The module contains an onboard TCP/IP and UDP stack accessible through ASCII commands over a UART interface at up to 921600 bps, so the host MCU sends human-readable commands to open sockets and transmit data without managing any 802.11 or IP layer protocols internally.
What Wi-Fi security protocols does RN1810E-I/RM110 support for enterprise and consumer network deployments?
The module supports WEP 64/128-bit, WPA-PSK (TKIP), and WPA2-PSK (AES) security modes, covering the authentication requirements of most consumer routers and light industrial Wi-Fi access points operating in the 2.4 GHz band.
Is RN1810E-I/RM110 suitable for automotive in-vehicle connectivity applications from a quality standpoint?
Yes. The module is screened to TS 16949 automotive quality standard and rated for a peak reflow temperature of 260°C, making it compatible with automotive-grade assembly processes and quality management systems used in telematics and fleet-monitoring applications.
What YTEOL value should procurement teams note when evaluating long-term availability of RN1810E-I/RM110?
The YTEOL value is listed as 0, indicating that this module may be at or approaching end-of-life status. Buyers with multi-year production programs should contact Microchip for a last-time-buy date and evaluate migration to a current-generation Wi-Fi module with a longer availability horizon.
