ESP32 Dual Core WiFi Bluetooth Development Board with SDIO interface

Description This ESP32 Board comes with Additional SDIO interface pins (SDO, SDI, and CLK). SDIO interface can be used for interfacing external memory cards for data logging applications and many other applications where high speed serial data communication is needed. 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 Additional SDIO Interface pins High performance-price ratio Small volume,easily embeded to other products Strong function with support LWIP protocol,Freertos Suppporting three modes: AP, STA, and AP STA Supporting Lua program, easily to develop Technical Specifications Part Number : ESP32 DEVKIT V1 Microcontroller: Tensilica 32-bit Single-/Dual-core CPU Xtensa LX6 Operating Voltage: 3.3V Input Voltage: 7-12V Digital I/O Pins (DIO): 25 Analog Input Pins (ADC): 6 Analog Outputs Pins (DAC): 2 UARTs: 3 SPIs: 2 I2Cs: 3 Flash Memory: 4 MB SRAM: 520 KB Clock Speed: 240 Mhz Wi-Fi: IEEE 802.11 b/g/n/e/i: [!] 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.
