The ESP32 is a development board developed by Espressif systems. It can be programmed using Arduino IDE and ESP-IDF. It has higher processing power than ESP8266 but it is more costly and bigger in physical dimension than ESP8266. It has a built in Bluetooth module and CAN protocol and SRAM. It has 36 GPIO Pins with a CPU clock of 160MHz. It has 12-bit ADC onboard and supports CAN, UART, I2C and I2S. It can be used in prototyping IoT products, Low power Battery operated application, small range networking projects, and with the projects which require many Input Output Pins and Wi-Fi and Bluetooth connectivity.

ESP32 WROOM-32 MCU Module Specifications

• Microprocessor : Tensilica Xtensa LX6
• Operating Voltage : 3.3V
• Analog Input Pins : 12-bit, 18 Channel
• DAC Pins: 8-bit, 2 Channel
• Digital I/O Pins : 39 (of which 34 is normal GPIO pin)
• SRAM : 520KB
• WiFi : 802.11 b/g/n

Product Description

To use this module you need to connect its USB mini port to your PC to write programs. It can take input upto 5V as it has an onboard voltage regulator but it is a 3.3V board so you must connect a logic level converter if you are planning to use V devices with it.
