Introduction

USR-C210 is a low-cost module in the USR-C21 series WiFi module family. It is a low-power 802.11 b/g/n module designed for wireless network communication in embedded systems. The module enables physical devices to connect to Wi-Fi networks, facilitating IoT control and management.

The module hardware integrates MAC, baseband chip, RF transceiver unit, and power amplifier. It features a built-in low-power operating mechanism for effective low-power operation, and supports WiFi and TCP/IP protocols — requiring only simple configuration to enable UART device networking.

The compact form factor allows easy soldering onto customer PCBs. The module supports both integrated and external antenna options, providing flexible deployment choices.
