Smart Factory Data Acquisition Systems\u003c\/h3\u003e\n\u003cp\u003eIn modern manufacturing facilities where the 2.4GHz spectrum is heavily congested by existing equipment and legacy Bluetooth devices, the E103-RTL8711DA series module leverages its 5.8GHz band capability. By integrating this module into industrial PLCs or Ebyte remote I\/O modules, automation engineers can ensure low-latency, interference-free transmission of critical sensor data to the local SCADA network via the STA mode.\u003c\/p\u003e\n\u003ch3\u003e2. Intelligent HVAC and Building Automation\u003c\/h3\u003e\n\u003cp\u003eFor smart home and commercial HVAC control panels, device configuration can often be complex. The BLE 5.0 capability of this module allows field technicians to use a smartphone app for quick, local Bluetooth provisioning (setting up Wi-Fi credentials). Once configured, the module switches to Wi-Fi to maintain a continuous, low-data-rate telemetry link to the central building management server.\u003c\/p\u003e\n\u003ch3\u003e3. Rapid IoT Gateway Prototyping\u003c\/h3\u003e\n\u003cp\u003eHardware startups and R\u0026amp;D engineers developing custom IoT gateways can utilize the E103-RTL8711DA-PS-TB test board to drastically reduce time-to-market. By plugging the test board directly into a standard breadboard and utilizing the TTL interface, developers can quickly interface the RTL8711DAF chipset with external microcontrollers or Ebyte LoRa nodes to validate dual-protocol data routing logic before committing to a custom PCB layout.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/14_9819c0db-c34d-4dc0-94c3-e16028da7300.jpg?v=1786001524\" alt=\"\"\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eFAQ Section\u003c\/h2\u003e\n\u003ch3\u003e1. What is the primary difference between the XS and PS versions of this module?\u003c\/h3\u003e\n\u003cp\u003eThe XS version (E103-RTL8711DA-XS) features a more compact footprint (16.5 x 16 mm) and provides a longer maximum transmission range (up to 710m on 5.8GHz). The PS version (E103-RTL8711DA-PS) has a slightly larger footprint (21.0 x 16 mm) with a range of up to 550m. Both utilize the same RTL8711DAF core chipset and support the same firmware protocols.\u003c\/p\u003e\n\u003ch3\u003e2. Can the Wi-Fi and BLE 5.0 protocols operate concurrently?\u003c\/h3\u003e\n\u003cp\u003eYes. The module integrates both hardware and software resources required for dual-protocol operation. A common use case is utilizing BLE 5.0 for localized, low-power device configuration or diagnostics, while the Wi-Fi interface concurrently handles long-range data uploading to a remote server.\u003c\/p\u003e\n\u003ch3\u003e3. Do I need an external MCU to operate the E103-RTL8711DA series?\u003c\/h3\u003e\n\u003cp\u003eWhile the module can handle network processing, it operates primarily as a UART-to-Wi-Fi\/BLE serial transceiver. You will typically interface it with a host microcontroller (MCU) or industrial PC that sends AT commands or raw serial data via the UART pins for transmission over the wireless network.\u003c\/p\u003e\n\u003ch3\u003e4. How can I easily evaluate the module without designing a custom PCB?\u003c\/h3\u003e\n\u003cp\u003eWe strongly recommend purchasing the E103-RTL8711DA-PS-TB Test Board. It comes pre-mounted with the PS module and includes a USB power interface, a TTL communication port, and standard pin headers. This allows you to connect it directly to your PC for AT command testing or plug it into a breadboard for peripheral integration.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Ebyte Official Store - IoT Module Manufacturer","offers":[{"title":"E103-RTL8711DA-XS","offer_id":48611209150669,"sku":"E103-RTL8711DA-XS","price":5.05,"currency_code":"USD","in_stock":true},{"title":"E103-RTL8711DA-XS+TX2400-JKS-IPX20","offer_id":48611209183437,"sku":"E103-RTL8711DA-XS+TX2400-JKS-IPX20","price":6.55,"currency_code":"USD","in_stock":true},{"title":"E103-RTL8711DA-PS","offer_id":48611209216205,"sku":"E103-RTL8711DA-PS","price":5.08,"currency_code":"USD","in_stock":true},{"title":"E103-RTL8711DA-PS-TB","offer_id":48611209248973,"sku":"E103-RTL8711DA-PS-TB","price":8.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/3034a1133efe01daba919094b70c6310_4f0f2c95-7c82-4e44-a958-47d94727dc90.jpg?v=1786000359","url":"https:\/\/ebyteiot.com\/zh\/products\/ebyte-e103-rtl8711da-rtl8711daf-dual-band-wifi-ble5-0-module","provider":"Ebyte Official Store - IoT Module Manufacturer","version":"1.0","type":"link"}
