Former product name: ESP-WROOM-02 Development Board
This product was renamed from ESP-WROOM-02 Development Board to ESPr Developer as of June 9th 2016.
It is a development board with ESP-WROOM-02 and USB Serial converter IC (FT231XS). It also has a 3.3 V output regulator, reset switch and an action mode switcher which enables you to use your ESP-WROOM-02 Wi-Fi right away.
ESP-WROOM-02 Development Board with pre-soldered headers. By using male/male jumper wires, you can easily connect this board to a breadboard without having to solder it.
ESP-WROOM-02 is a 32-bit low power micro-controller (MCU) Wi-Fi Module that integrates TCP/IP network stacks, and includes 10-bit ADC with HSPI, SDIO, UART, PWM, I2C, and I2S interfaces.
The highlight of this board is an FT231X USB-to-Serial converter. That's what translates data between your computer and ESP-WROOM-02.
Also defects might occur when using VIN pin with Rev.2 on the back.This has been improved from Rev.3.All the products have switched to Rev.3 as of July 29th 2016.
