WiFi modules are compact electronic components that enable devices to connect to wireless networks. They typically consist of a microcontroller, radio transceiver, and antenna, allowing for seamless communication over WiFi. These modules are widely used in Internet of Things (IoT) applications, enabling smart devices to transmit and receive data over the internet.
| Frequency Bands | 2.4 GHz and 5 GHz |
| Protocols Supported | 802.11 b/g/n/ac |
| Operating Voltage | 3.3V to 5V |
| Data Rate | up to 600 Mbps |
| Antenna Type | Integrated or external |
| Dimensions | Typically 10mm x 10mm to 30mm x 30mm |
| Power Consumption | Varies by module, typically 50mA to 200mA |
When selecting a WiFi module, consider the required frequency bands and data rates for your application. It's important to specify the operating voltage and power consumption needs, as well as the type of antenna suitable for your device. Additionally, inquire about certifications such as FCC or CE compliance, especially for consumer products. Quantities may affect pricing, so be clear about your order volume when requesting a quote.
