Description PaperMono is a development board featuring a 3.97-inch touch-enabled monochrome E- Paper display driven by the SSD1677 controller at a resolution of 480x800, supporting 1-bit black-and-white rendering. It integrates an FT6336G touch controller and a front-light illumination system for comfortable reading in dark or low-light environments. Powered by the ESP32-S3R8 SoC equipped with 16 MB flash memory and 8 MB PSRAM, it supports a 40MHz crystal oscillator, it supports 2.4 GHz Wi-Fi, BLE wireless communication. The board incorporates a buzzer, a PDM microphone (LMD4737T261-AC02), an RGB LED, a BMI270 6- axis IMU, an M5IOE1 IO expander, a microSD card slot, and an RX8130CE real-time clock. NFC capability is provided by the ST25R3916 high-performance frontend chip, supporting ISO14443A, ISO14443B, FeliCa™, and ISO15693 protocols for reliable read/write operations with various NFC/RFID tags and cards, with reader mode, card emulation mode, custom protocol support, automatic antenna tuning, and high-sensitivity reception. LoRa communication is based on the SX1262 chip (Stamp LoRa-1262) with a built- in FPC antenna, supporting the 868–923 MHz band with strong anti-interference and long- range communication capabilities. Combined with the M5PM1 multi-level power management system and a 1150mAh lithium battery, it delivers sustained low-power operation. Suitable for e-readers, electronic signage, access control systems, identity authentication, intelligent transportation, and other IoT and embedded applications.

Report No.: 2604T59815E-RF-22C Rev:A/4.0(2024/11/01) Page 11 of 51 TR-4-E-R007 RF EXPOSURE Applicable Standard According to KDB447498 D01 General RF Exposure Guidance v06: 4.3. General SAR test exclusion guidance c) For frequencies below 100 MHz, the following may be considered for SAR test exclusion (also illustrated in Appendix C): 1) For test separation distances > 50 mm and < 200 mm, the power threshold at the corresponding test separation distance at 100 MHz in step b) is multiplied by [1 + log(100/f(MHz))] 2) For test separation distances ≤ 50 mm, the power threshold determined by the equation in c) 1) for 50 mm and 100 MHz is multiplied by ½. 3) SAR measurement procedures are not established below 100 MHz. Result For NFC, the power of EUT: E Field@3m is 66.65dBuV/m =-28.55dBm(0.0014mW) Note: E[dBμV/m] = EIRP[dBm] + 95.2for d = 3 m. SAR test exclusion threshold for NFC(13.56MHz) separation distance < 50mm =[474*(1 + log(100/f(MHz)))]/2 = 443mW >0.0014mW Result: Compliance.
