TheWioCore is an ESPWROOM02 WiFi IoT module preloaded with Wio platform firmware, making it fully compatible with Wio Link and Wio Node hardware/software. It integrates TCP/IP stacks, multiple peripheral interfaces, and advanced power management for ultralow power operation. Its compact footprint (18 20 mm) makes it ideal for wearables, mobile devices, and embedded IoT applications.

Description

The MCU module is the brain of any IoT board. To simplify IoT development, Seeed introduced Wio Link and later Wio Node, both based on the popular ESP8266 SoC. The WioCore builds on ESPWROOM02, replacing the original firmware with Wio platform firmware. This ensures full compatibility with Wio Link and Wio Node, while offering cloud integration and OTA updates. Certified (FCC, CE, KCC, TELEC, LCIE, IC), the WioCore delivers reliable WiFi connectivity and ultralow power consumption, making it one of the best solutions for wearables, mobile devices, and IoT applications.
