II. Core Technical Features
UART Transparent Transmission Technology
The majority of EBYTE WiFi modules (such as E103-W01, W02, W05, W10) integrate UART transparent transmission functionality. Users only need to configure the module via the serial port (UART) using AT commands to establish a WiFi connection. Once configured, serial port data is automatically forwarded through the WiFi network, enabling a "plug-and-play" experience that significantly lowers the barrier to wireless application development.Multiple Operating Modes
EBYTE WiFi modules support the following three basic operating modes:
AP Mode: The module acts as a hotspot, allowing other devices to connect.
STA Mode: The module acts as a client, connecting to an existing WiFi network.
STA+AP Mode: Operates simultaneously as both AP and STA, enabling data bridging.
- Dual-Mode and Dual-Band Technology
Dual-Mode WiFi (WiFi+BLE): Supports both WiFi and Bluetooth Low Energy simultaneously, e.g., E103-W08, E101-32 series, E103-W14 series.
Dual-Band WiFi (2.4G+5G): Supports both 2.4GHz and 5GHz frequency bands, e.g., E103-W06 (CC3235S), E103-RTL8812CU.
- Low-Power Technology
E103-W12 Series (DA16200): Power consumption can be as low as microamp levels while maintaining a WiFi connection, ideal for battery-powered devices.
E103-W02 Series (CC3200): Supports 4 power modes, with minimum standby current less than 5µA.
E103-W14 Series: Supports low-power mode, with STA and BLE slave modes operating simultaneously.
III. Application Scenarios and Selection Solutions
