GXN32C3N4E — 20 Mbps WiFi Module: Wireless Sensor Link for Robots & Robot Dogs

SPI/UART to WiFi · 20 Mbps TCP · Wireless Sensor Data · Robot Test Platforms

The GXN32C3N4E is a high-speed WiFi transparent transmission module that converts SPI and UART serial data to wireless WiFi communication. With 20 Mbps actual TCP throughput and SPI clock up to 35 MHz, it serves as the wireless sensor data link on robot and robot-dog test platforms — streaming joint torque, IMU and strain-gauge ADC data to host systems without cables or protocol changes — and as a wireless DAQ node in bridge & tunnel vibration monitoring and industrial IoT. It supports up to 4 simultaneous TCP/UDP connections for flexible multi-client architectures.

Typical Applications

Robot & Robot-Dog Sensor Link

Wirelessly stream joint torque, IMU and strain-gauge ADC data from robot and robot-dog test platforms to host systems — transparent transmission, no firmware changes on the sensor side.

Wireless DAQ / SHM Nodes

Transmit high-speed ADC sampling data from vibration sensors on bridges and tunnels to central monitoring systems via WiFi, eliminating long cable runs.

Industrial Automation

Enable wireless communication between PLCs, sensors, and control systems in factory environments where wired connections are impractical.

IoT & Embedded Gateway

Serve as a WiFi bridge for embedded devices, converting UART/SPI data to IP packets for cloud connectivity and remote monitoring.
