Toradex Wi-Fi/BT enabled SoMs support dual antenna configuration. Dual antenna operation is recommended and default configuration to obtain maximum throughput and stability performance through the usage of MIMO. If for whatever reason operation with a single antenna is required, please follow this guide.
