ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA

The ESP32 integrated with Antenna switches, RF Balun, power amplifiers, low-noise amplifiers, filters, and management modules, and the entire solution occupies the least area of PCB. 2.4 GHz Wi-Fi plus Bluetooth dual-mode chip, with TSMC Ultra-low power consumption 40nm technology, power dissipation performance and RF performance is the best, safe and reliable, easy to extend to a variety of applications.

Features:
The ESP32 is dual core, this means it has 2 processors.
It has Wi-Fi and bluetooth built-in.
It runs 32 bit programs.
The clock frequency can go up to 240MHz and it has a 512 kB RAM.
This particular board has 30 or 36 pins, 15 in each row.
It also has wide variety of peripherals available, like: capacitive touch, ADCs, DACs, UART, SPI, I2C and much more.
It comes with built-in hall effect sensor and built-in temperature sensor.

Data Feature: Complete microcontroller with WLAN (802.11bgn) and Bluetooth (Classic and LE). Reset and boot buttons are available, so a new firmware can be quickly and easily installed. The ESP32 combines a CPU with 2 Tensilica LX6 cores, clocked at up to 240 MHz, and 512 kilobytes SRAM in a single microcontroller chip.
