Product Overview
Wio-S3 wireless module is embedded with the ESP32-S3R8 dual core Xtensa® LX7 MCU and the long range SX1262 LoRa chip. It supports LoRaWAN frequency plan on EU868 and US915, as well as 2.4GHz Wi-Fi and BLE 5.0 connectivity. It integrates 16MB Flash and 8MB PSRAM, making it ideal for edge AI processing. This version is equipped with an onboard IPEX antenna connector, allowing the use of an external antenna. Equipped with a TCXO, it ensures stable and accurate RF performance, which is suitable for IoT applications that require long range, high performance, and reliable wireless communication.
Note: For Wio-S3 antenna selection, we provide the following references to help improve RF performance and ensure compliance with CE/FCC regulations: For LoRa: Dipole Antenna (up to 2.00 dBi): This antenna is used for Wio-S3 certification. For more information, please refer to SKU 113070002 . We also provide the LoRa Antenna Kit ( SKU 110061501 ) , which includes the dipole antenna and an SMA to I-PEX antenna cable for easier integration. The SMA to I-PEX antenna cable is also available separately. For more information, please refer to SKU 321990397 . Wio-S3 is an ultra-compact wireless module designed for IoT devices. It combines the high-performance ESP32-S3R8 dual core processor with the SX1262 LoRa chip to provide reliable long range communication. This module is a versatile solution for developers. It supports LoRaWAN on EU868 and US915 bands, and also provides stable Wi-Fi and BLE 5.0 connectivity. With 16MB Flash and 8MB PSRAM, Wio-S3 offers plenty of memory for edge AI tasks and complex data processing. Wio-S3 is designed with hardware flexibility to meet various integration needs. We offer two versions of the module: one with an onboard IPEX connector and one without an IPEX connector.
