ESP32 WROOM32 DevKit WiFi Bluetooth Development Board

Description ESP32 has integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters, and power management module. The entire solution takes up the least amount of printed circuit board area.This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips by TSMC 40nm low power technology, power and RF properties best, which is safe, reliable, and scalable to a variety of applications. The ESP32 doesn’t replace the ESP8266, but it does improve on it in every aspect. Not only does it have WiFi support, but it also features a Bluetooth 4.2 radio, making it even more versatile. The CPU is similar to the ESP8266 – it’s a 32-bit Xtensa® LX6, but the ESP32 has two cores! There’s also 128KB of ROM and 416KB SRAM, but Flash memory (for program and data storage) is still left up to an external chip (up to 64MB). Features High performance-price ratio Small volume, easily embeded to other products Strong function with support LWIP protocol, Freertos Supporting three modes: AP, STA, and AP STA Supporting Lua program, easily to develop Based on ESP-WROOM-32D chip Technical Specifications Analog-to-Digital Converter (ADC) – Up to 16 channels of 12-bit SAR ADC’s. The ADC range can be set, in firmware, to either 0-1V, 0-1.4V, 0-2V, or 0-4V – no more weird 0-1V ADC! Digital-to-Analog Converter (DAC) – Two 8-bit DAC’s to produce true analog voltages Pulse-Width Modulation (PWM) – Up to 16 channels of PWM-capable pins for dimming LEDs or controlling motors Touch Sensor – 10 GPIOs feature capacitive sensing; make a 10-key buttonpad! UART – Two UART interfaces, one is used to load code serially. They feature flow control, and support IrDA too! I2C, SPI, I2S – There are two I2C and four SPI interfaces to hook up all sorts of sensors and peripherals, plus two I2S interfaces if you want to add sound to your project. [!] Notes: Programming Issue over USB Interface: ESP32 Devkit v1 boards did not have 1uf capacitor from EN pin to GND. This missing capacitor can cause unable to program issue on Windows and other operating systems. To fix this issue install a 1uf capacitor between EN and GND pin. If you do not want to install 1uF capacitor between EN and GND then you can still program the boards by holding down the BOOT push button manually until programming begins.
