[Introduction]:The EWM103-W15 series is a low-cost, cost-effective Wi-Fi + Bluetooth dual-mode WiFi module developed by Ebyte. It complies with Bluetooth 5.1 and IEEE 802.11b/g/n standards. The module integrates the hardware and software resources required for complete Wi-Fi and Bluetooth applications, supporting both AP and STA Wi-Fi operating modes and Bluetooth low energy consumption. It is ideal for low-speed applications and data acquisition, such as smart homes and industrial control.
| Pin number | Pin Name | Pin Type | Pin Purpose |
