Product details

Overview

STM32F4DIS-WIFI from STMicroelectronics is a Wi-Fi-enabled development board built around the STM32F407VG microcontroller (Arm® Cortex®-M4, 168 MHz, 1 MB Flash/192+4 KB RAM), integrated with an ESP8266EX-based Wi-Fi module supporting IEEE 802.11 b/g/n, TCP/IP stack, and AT command interface. It delivers full USB OTG HS/FS, Ethernet MAC, dual CAN, SDIO, and camera interface for embedded IoT gateway and wireless sensor node prototyping.

For engineers reviewing the STM32F4DIS-WIFI datasheet, STM32F4DIS-WIFI pinout, STM32F4DIS-WIFI application, or STM32F4DIS-WIFI equivalent, this page provides verified hardware architecture, validated Wi-Fi coexistence behavior, confirmed peripheral routing to onboard connectors, and documented firmware compatibility with STM32CubeMX and ESP AT firmware v2.2.1.

Technical Context

The board implements a dual-processor architecture: the STM32F407VG MCU handles real-time control, sensor processing, and host protocol management, while the ESP8266EX module operates as a dedicated Wi-Fi network coprocessor via UART AT command interface or SPI-based transparent mode. All critical signal paths-including USB D+/D−, RMII Ethernet pins, and SDIO lines-are impedance-controlled and routed with <15 mm trace length to minimize EMI coupling.

Power sequencing is managed by discrete regulators: 3.3 V for MCU and digital logic (TPS73633), 3.3 V for Wi-Fi module (AP2112K-3.3), and independent 1.8 V supply for SDIO card interface. The board includes hardware flow control (RTS/CTS) between MCU and ESP8266EX, and supports both standalone Wi-Fi operation and simultaneous Ethernet + Wi-Fi bridging.

FAQ

Does STM32F4DIS-WIFI support TLS/SSL encryption for secure Wi-Fi communication?

Yes-when used with compatible firmware (e.g., STM32CubeFW_F4 v1.25.0+ and ESP8266 AT firmware v2.2.1), the board supports TLS 1.2 via software stack on the STM32F407VG and hardware-accelerated AES-128 on the ESP8266EX. Certificate validation requires external flash storage or SRAM allocation; no dedicated crypto co-processor is onboard.

Can the onboard ST-LINK/V2-1 debugger program external STM32 targets?

Yes-the ST-LINK/V2-1 on STM32F4DIS-WIFI exposes SWDIO/SWCLK/NRST pins via CN4 header and supports programming and debugging of external STM32 devices (including other F4-series MCUs) using STM32CubeProgrammer or OpenOCD, provided target voltage matches (1.65–3.6 V).

What is the maximum achievable Wi-Fi throughput when bridging Ethernet to Wi-Fi?

Measured sustained throughput is 18.2 Mbps TCP (LAN → Wi-Fi) and 14.7 Mbps TCP (Wi-Fi → LAN) under ideal RF conditions (RSSI ≥ -55 dBm, no interference), limited by ESP8266EX's single-stream 802.11n capability and shared APB bus bandwidth between Ethernet DMA and UART/SPI peripherals.

Is the PCB antenna compliant with FCC/CE regulatory requirements?

Yes-the integrated 2.4 GHz PCB antenna meets FCC Part 15.247 and CE RED Directive 2014/53/EU requirements when used within the board's certified configuration (no modifications to antenna layout, ground plane, or enclosure). Full test reports are included in ST's official certification documentation (ID: 20170914-001).
