OSOYOO OSOLINK WIFI/BLE I/O shield
The OSOLINK WiFi/BLE I/O Shield v1.0 is a wireless communication expansion board designed for Arduino Uno, Arduino Mega 2560, and other Arduino-compatible development boards that use the standard Arduino pin layout. It is built around the Espressif ESP32-C3-MINI-1-N4 module, which integrates a single-core RISC-V processor running at up to 160 MHz, 4 MB of built-in flash, IEEE 802.11 b/g/n Wi-Fi, and Bluetooth 5.0 (BLE) in a compact SMD package.
Unlike previous generation shields that used the ESP8266, the ESP32-C3 offers a significantly upgraded feature set: dual-mode wireless (Wi-Fi + BLE simultaneously), enhanced security (WPA3, TLS 1.3), more GPIOs, and built-in USB Serial/JTAG for easier development. The shield communicates with the host Arduino via UART, using a configurable UART Selector jumper that lets you choose between the hardware serial port (D0/D1) or a software serial port (D4/D5), avoiding conflicts with the Arduino’s programming interface.
