Introduction 1.Introduction 1.1. T-BEAM 1W T-BEAM 1W is a development board. It can work independently. It consists of ESP32-S3 MCU supporting Wi-Fi + BLE communication protocol and motherboard PCB. This product also features a 1.3-inch 128x64 OLED display. And this product has GPS positioning and LoRa function. LoRa chip is SX1262. For applications ranging from low-power sensor networks to the most demanding tasks. At the core of this module is the ESP32S3R8 chip. ESP32-S3 integrates Wi-Fi (2.4 GHz band) and Bluetooth 5.0 solutions on a single chip, along with dual high performance cores and many other versatile peripherals. ESP32 provides a robust, highly integrated platform to meet the continuous demands for efficient power usage, compact design, security. Xinyuan provides the basic hardware and software resources that empowers application developers to build their ideas around the ESP32-S3 series hardware. The software development framework provided by Xinyuan is intended for rapidly developing Internet-of-Things (IoT) applications, with Wi-Fi, Bluetooth, flexible power management and other advanced system features. The manufacturer is Shenzhen Xin Yuan Electronic Technology Co., Ltd. 1.2. Arduino A set of cross-platform applications written in Java. The Arduino Software IDE is derived from the Processing programming language and the integrated development environment of the Wiring program. Users can develop applications in Windows/Linux/ MacOS based on Arduino. It is recommended to use Windows 10. Windows OS has been used as an example in this document for illustration purposes. 1.3. Preparation To develop applications for ESP32-S3 you need: •PC loaded with either Windows, Linux or Mac operating system •Toolchain to build the Application for ESP32-S3 •Arduino that essentially contains API for ESP32-S3 and scripts to operate the Toolchain •C…

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2601P23809E-RF-00A TR-EM-RF004 Page 26 of 115 Version 4.1 RF EXPOSURE EVALUATION MPE-Based Exemption Applicable Standard According to subpart 15.247 (i) and subpart 2.1091 systems operating under the provisions of this section shall be operated in a manner that ensures the public is not exposed to RF energy level in excess of the communication guidelines. According to KDB 447498 D04 v01 Interim General RF Exposure Guidance MPE-Based Exemption: General frequency and separation-distance dependent MPE-based effective radiated power(ERP) thresholds are in Table B.1 [Table 1 of § 1.1307(b)(3)(i)(C)] to support an exemptionfrom further evaluation from 300 kHz through 100 GHz. Ris the minimum separation distance in meters f = frequency in MHz For multiple RF sources: Multiple RF sources are exempt if: in the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation: Bay Area Compliance Laboratories Corp.
