Jimb0 @ sparkfun.com takes a first look on the new ESP32 WiFi board by Espressif that’s an improvement of the ESP8266 board.
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).
