Go from Module Selection to a Working Project
Discover how the Wio family supports your journey from early evaluation to real-world deployment, with setup guides, reference designs, SDKs, KiCad libraries, hands-on testing, and projects built by developers. Explore connectivity options across LoRa, Wi-Fi, BLE, GNSS, and more, then find the module and purchasing path that match your technical requirements, location, and development stage.
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. This provides developers with flexible options to choose the best antenna path for their hardware design.
To ensure consistent performance in different environments, it also includes a TCXO for high frequency stability.Small in size but powerful in performance, Wio-S3 module is ideal for many industries. It is perfect for applications such as smart home systems, industrial automation, smart agriculture, low-power IoT sensor hubs and so on.
With this module, you can connect to different LoRaWAN server platforms like TheThingsNetwork, Chirpstack, and others.
