ESP32 NODEMCU-32S ESP-32S Kit: high resolution pinout, datasheet, and specs

Link to the high resolution pinout image

The NODEMCU-32S is a highly versatile and powerful microcontroller board based on the ESP32 chipset. It stands out for its breadboard-friendly design, which is a significant advantage over the DevKit V4 model. This feature makes it particularly suitable for prototyping and educational purposes, as it can be easily inserted into a breadboard without requiring additional wiring or complex setup. The board includes built-in Wi-Fi and Bluetooth capabilities, a dual-core processor, and a variety of input/output options, including digital and analog pins, SPI, I2C, and UART interfaces. Its compact size, combined with its extensive functionality and ease of use, makes the NODEMCU-32S an ideal choice for a wide range of applications, from simple DIY projects to more complex IoT (Internet of Things) developments.
