Description The Seeed Studio Wio-S3-N Wireless Module without IPEX is an ultra-compact Wio-S3 wireless module for IoT, LoRaWAN and edge AI device integration. It combines an ESP32-S3R8 dual-core Xtensa LX7 MCU with an SX1262 LoRa transceiver, giving designers one module for long-range LoRaWAN communication plus Wi-Fi and BLE 5.0 connectivity. This ESP32-S3 LoRaWAN module supports EU868 and US915 LoRaWAN frequency plans, 2.4GHz Wi-Fi, BLE 5.0, 16MB Flash, 8MB PSRAM and a TCXO for stable RF performance. The Wio-S3-N module without IPEX version is intended for designs that use the onboard PCB antenna path instead of an external IPEX antenna connector. Use the Wio-S3-N wireless module for low-power IoT sensor nodes, smart agriculture, industrial monitoring, remote data logging, wearable devices and compact AIoT interfaces. It includes built-in command firmware support and can also be used for custom product development with an SDK. Features ESP32-S3R8 + SX1262 architecture for Wi-Fi, BLE 5.0 and LoRa communication in one compact module. LoRaWAN EU868 / US915 support for long-range IoT deployments and remote sensor networks. 16MB Flash and 8MB PSRAM provide memory headroom for edge AI, buffering and advanced firmware. TCXO improves RF frequency stability for reliable wireless performance. Without IPEX connector, designed for onboard PCB antenna integration. Rich GPIO expansion including UART, I2C and ADC for peripheral integration. Built-in command firmware and SDK support simplify IoT module development. FCC, CE and Telec certified according to the official Seeed Studio page.
