Based on the ESP32-S2FN4R2 WLAN IC, this compact development module gives you Wi‑Fi connectivity, flexible I/O and broad peripheral support while running MicroPython for fast prototyping and deployment. Key benefits Fast development with MicroPython compatibility: write and iterate code quickly without low-level toolchains. Wide hardware flexibility: 27 digital input/output pins let you connect many sensors, actuators and peripherals from a single board. Reduced external components: built-in support for ADC, I2C, SPI, UART, one‑wire and USB OTG minimizes the need for extra chips or adapters. Responsive and multitasking capable: all GPIO pins support interrupts and PWM, so you can handle real-time inputs and motor or LED control reliably. Core features Processor: based on ESP32-S2FN4R2 WLAN IC (Wi‑Fi capable). I/O: 27 digital input/output pins. Pin capabilities: all pins support interrupts and PWM. Peripheral interfaces: ADC, I2C, SPI, UART, one‑wire. USB: OTG support for direct host/device USB connections. Software: compatible with MicroPython. How this solves common problems Simplifies IoT integration: built-in Wi‑Fi and common interfaces let you connect devices to cloud or local networks without extra networking hardware. Speeds prototyping: MicroPython support removes compile cycles and lowers the barrier for testing ideas and demos. Handles mixed workloads: many GPIOs with interrupt and PWM support allow a single board to read multiple sensors, run control loops, and drive actuators simultaneously. Eases connectivity to peripherals: native I2C/SPI/UART/one‑wire interfaces let you attach displays, sensors, storage, and serial devices without protocol converters. Practical use scenarios Remote sensor node: collect analog and digital sensor data via ADC and GPIOs, and send readings over Wi‑Fi to a server or cloud service. USB‑connected data logger or configuration tool: use USB OTG to act as host or device for direct file transfer, firmware updates, or local control from a laptop. Rapid prototype for home automation: control relays, servos and LEDs with PWM, read temperature/humidity sensors via I2C or one‑wire, and run control logic in MicroPython for fast iteration. What to expect in performance and compatibility Networked projects with Wi‑Fi connectivity provided by the ESP32‑S2FN4R2 IC. Real‑time responsiveness on GPIO events via interrupts and PWM on all pins. Broad peripheral support (ADC, I2C, SPI, UART, one‑wire) for common sensors and modules. Native MicroPython support for quick development and easy code maintenance. This module is suited for engineers, makers and educators who need a Wi‑Fi capable microcontroller with many I/O options and convenient MicroPython development.
