Compact ESP32-S2FN4R2 Wi‑Fi module with high-density I/O and USB-C connectivity Key benefits Maximum interface flexibility: All digital I/O pins support interrupts, PWM, I2C, one-wire and ADC functionality, so you can connect a wide range of sensors and actuators without extra interface chips. Built-in USB OTG via Type-C: Use the module as a device or host for direct USB accessory connection and straightforward firmware loading or data transfer. Proven Wi‑Fi performance: Based on the ESP32-S2FN4R2 WLAN IC, the module delivers reliable wireless connectivity for IoT and edge applications. Space-efficient integration: 1.27 pitch digital headers provide a compact, board-level connection option for high-density designs. What it does and how it solves problems Consolidates multiple interfaces (I2C, SPI, UART, ADC, PWM, one-wire, interrupts, USB OTG) into a single module, eliminating the need for multiple companion chips and reducing PCB complexity. Simplifies prototyping and production: standard 1.27 pitch pins make it straightforward to route signals to custom PCBs or plug into compatible connectors for modular designs. Enables both data collection and peripheral control: native ADC and one-wire support handle sensors and temperature probes while PWM and interrupts support motors, LEDs, and real-time event handling. Technical highlights I/O: 1.27 pitch digital input/output pins; universal pin functions include interrupt, PWM, I2C, one-wire and ADC support Protocols: I2C, SPI, UART supported USB: Type-C physical connector with USB OTG capability Core: Based on ESP32-S2FN4R2 WLAN IC Typical applications Wi‑Fi sensor node: Connect multiple analog and digital sensors directly to the module using ADC, one-wire and I2C, and stream readings over Wi‑Fi for remote monitoring. USB-enabled gateway or data logger: Use USB OTG to attach USB drives or peripherals, and bridge serial devices (UART) or SPI sensors to a Wi‑Fi backend for data aggregation. Compact control unit for robotics or lighting: Use PWM for motor or LED control, interrupts for real-time event handling, and I2C/SPI to add displays or sensor arrays. Compatibility and integration tips Designed for high-density PCB mounting via 1.27 pitch headers; plan connector footprint accordingly. Exposes standard serial and bus interfaces (UART, I2C, SPI) for easy integration with external peripherals and microcontrollers. USB-C simplifies connection and supports OTG use cases; ensure host/device roles are handled in your system design. This module provides a compact, feature-rich platform for Wi‑Fi connected projects that require versatile I/O, USB OTG capability, and the ESP32-S2FN4R2 wireless core.
