ESP32-S2FN4R2-based wireless controller with Type-C USB and extensive, flexible I/O Key benefits Ready-made Wi‑Fi core: Built around the ESP32-S2FN4R2 WLAN IC to provide integrated wireless connectivity without extra radio modules. Flexible connectivity: Type-C USB plus USB OTG support lets the board act as host or device for storage, input devices, or USB peripherals. Maximum I/O flexibility: 27 digital input/output pins that can be assigned for interrupts, PWM, 1‑Wire, I2C, or ADC — enabling a wide variety of sensors and actuators on a single board. Broad protocol support: Native I2C, SPI, and UART interfaces make it straightforward to connect displays, sensors, radio modules, and other common peripherals. Simplifies design and prototyping: High pin count and multi-protocol support reduce the need for external expanders and simplify wiring and firmware integration. Technical highlights Core: ESP32-S2FN4R2 WLAN IC USB: Type-C connector with USB OTG support I/O: 27 digital input/output pins; each pin supports interrupts, PWM, 1‑Wire, and ADC functions Communication interfaces: I2C, SPI, UART, USB OTG Practical applications IoT sensor hub: Collect analog and digital sensor data across many channels, aggregate locally, and send readings via Wi‑Fi to cloud services or a local server. USB-enabled edge device: Use Type-C and USB OTG to attach USB flash drives, keyboards, or cameras for data logging, local control, or human interface tasks while maintaining Wi‑Fi connectivity. Robotics and automation controller: Drive multiple motors and servos with PWM outputs, monitor encoders and switches via interrupt-capable inputs, and communicate with motor controllers or displays over SPI/I2C. Compatibility and integration Multiple standard interfaces (I2C, SPI, UART, USB OTG) allow integration with a wide range of sensors, actuators, and peripherals. High pin count and per-pin ADC/interrupt/PWM support reduce external hardware needs and shorten development cycles. Suitable for embedded projects, prototypes, and small-scale production where Wi‑Fi and flexible I/O are required. What makes it stand out Combines the ESP32-S2FN4R2 WLAN IC with a Type-C USB port and USB OTG capability on a single module. Large number of multi-function pins lets you consolidate sensor, actuator, and communication needs on one board. Designed to simplify connectivity and reduce the number of separate modules required for wireless, USB, and peripheral interfacing.
