Realtek RTL8711F SoC Chip Based Wireless Module (Wi-Fi 6 + BLE5.0 Dual-band)

Realtek RTL8711F SoC Chip Based Wireless Module (Wi-Fi 6 + BLE5.0 Dual-band)

The DL-SW711FA is a dual-band Wi-Fi 6 and Bluetooth LE 5.0 wireless SoC module powered by the Realtek RTL8711F chip (AmebaGreen2 platform). It features a dual-core Real-M300 processor running at up to 240 MHz, compatible with the Arm Cortex-M55 instruction set (Armv8.1-M). The module supports IEEE 802.11 a/b/g/n/ac/ax with 1T1R dual-band operation (2.4 GHz and 5 GHz), delivering data rates up to 114.7 Mbps. For security, it supports WPA/WPA2/WPA3 and hardware-level TrustZone isolation.

It includes 512 KB on-chip SRAM, 152 KB shared Bluetooth SRAM, and 4 MB onboard NOR Flash. The device offers a rich set of peripherals including UART, SPI, I2C, USB 2.0, SDIO, ADC, PWM, I2S, and 21 configurable GPIOs. It supports firmware flashing and debugging via SWD or UART interfaces. With an operating temperature range of -40°C to +105°C and a compact 23.15 x 17.5 x 3 mm SMD package, the DL-SW711FA is ideal for IoT, smart home, industrial automation, smart healthcare, and wearable applications.

Remark: this RF module is equipped with an IPEX-1 socket; however, it outputs signals via the PCB onboard antenna by default. If an external antenna is required (via the IPEX-1 socket), advance notice is necessary, as certain parameters must be modified during production.
