The ESP32 microcontroller from Espressif is one of the most powerful and popular solutions for IoT, thanks to its built-in Wi-Fi, Bluetooth, and dual-core processing.
While ready-made boards like the ESP32 DevKitC and NodeMCU-32S are widely available, they are often too large and include power-hungry voltage regulators and USB-to-UART chips. These features make them less suitable for compact, battery-operated IoT devices. To overcome these limitations, weโll design a custom ESP32 board optimized for small size, low power consumption, and battery operation.

By removing unnecessary ICs and using efficient power converters, this DIY ESP32 board achieves lower power consumption and compact design, making it ideal for IoT projects powered by small lithium-ion batteries.
Whether youโre building wireless sensors, data loggers, or portable IoT gadgets, this project will give you a solid foundation to create your own custom ESP32 hardware.
