Energy saving The ESP32 is a chip designed with TSMC technology for extremely low power consumption (ultra-low power management), allowing for the best power and performance with its high efficiency. As the quiescent current of the ESP32 chip is less than 5 μA it is particularly suitable for use with batteries or rechargeable batteries Compatible It has a similar pin layout to the conventional D1 Mini ESP8266-12F and is therefore pin-compatible with most accessories for it. Parameter Power supply voltage (USB) 5V DC Input/Output voltage 3.3V DC Operating current min. 500mA CPU Xtensa single-dual-core 32-bit-LX6 RAM 512kB I/O Pins 34 ADC channels 18 ADC Resolution 12-bit DAC channels 2 DAC Resolution 8-bit Communications interfaces SPI, I2C, CAN, UART Max current drawn per GPIO pin 40mA WiFi protocols 802.11 b/g/n (802/11n up to 150 Mbps) Package： 3 * ESP32 D1 mini

Designed with ultra-low power technology, it offers the full range of performance and features of the ESP32 chip. The pin arrangement provides compatibility with the modules developed for the D1 Mini ESP8266 while also offering fast WLAN, enhanced GPIO, Bluetooth functionality, and with its higher performance, a wider range of applications. D1 Mini NodeMCU ESP32 ESP-WROOM-32 WLAN WiFi Bluetooth IoT Development Board 5V Compatible with Arduino. All I/O pins have interrupt, PWM, I2C and one-wire capability, except the pin DO. 100% compatible with Arudino IDE, Lua and Micropython, it shows robustness, versatility, and reliability in a wide variety of applications and power scenarios.
