Through in-depth research on customer needs, EBIT has recently launched two multi-functional development boards designed for LoRa modules, embedded with LoRa communication module EBIT22-400/900MM22S and main control MCU ESP32-S3 chip, which supports LoRa, Wi-Fi and Bluetooth LE communication.
EoRa PI is based on Espressif's ESP32-S3FH4R2 chip and LoRa module, EoRa-S3-400TB (400 frequency band) and EoRa-S3-900TB (900 frequency band), which integrate a Type-C interface, LoRa module E22-400/900MM22S, a 0.96-inch OLED display, an SD card slot, a lithium battery charging circuit and a power supply circuit.
The ESP32-S3 is a low-power MCU system-on-chip (SoC) that supports 2.4 GHz Wi-Fi and Bluetooth® LE wireless communications. The chip integrates a high-performance Xtensa®32-bit LX7 dual-core processor, ultra-low-power coprocessor, Wi-Fi baseband, Bluetooth baseband, RF module and peripherals, with a maximum frequency of 240MHz and built-in 384KB ROM, 512KB SRAM, and 16KB RTC SRAM. THE ESP32-S3FH4R2 PACKAGE ALSO INTEGRATES AN ADDITIONAL 4MB FLASH AND 2MB PSRAM.
