Heltec Automation ESP32 WiFi Kit 32 V3 mit OLED Display

The Heltec ESP32 WiFi Kit 32 V3 is a powerful development board for IoT applications. It is based on the ESP32-S3FN8 processor, which is clocked at up to 240 MHz and supports both Wi-Fi and Bluetooth 5. Compared to its predecessor, the power consumption in deep sleep mode has been significantly reduced, and the USB interface has been upgraded from Micro-USB to USB-C. Additionally, an improved RF circuit ensures optimized signal transmission. The board features a built-in 0.96-inch OLED display that can be used to show debugging information or system status. Another highlight is the integrated lithium battery management system, which allows for safe charging and discharging. The numerous GPIO interfaces and communication protocols such as UART, SPI, and I2C make it ideal for versatile applications. Whether for smart homes, industrial automation, or DIY projects, the Heltec ESP32 WiFi Kit 32 V3 offers a powerful and flexible platform.
