2. GENERAL PRODUCT DESCRIPTION
Overview
The WE310F5-I/P is a module with a single-band Wi-Fi/BLE (5.0) 2.4GHz combo module
that provides an easy and cost-effective way for users to add wireless connectivity to
their products. This module is available in two different factors the antenna version
named WE310F5-I with 15mmx18mm dimensions and an on-board multilayer antenna
and the WE310F5-P with 13.1mmX14.3mm with antenna pad. The two versions share the
same Pinout and are P2P compatible.
Product Variants and Frequency Bands
The Telit WE310F5 module is available in two variants. For details on the differences
between the two variants.
