It has been about one year since the announcement of ESP32 SoC and the beginning of its beta testing for some developers.
Last Month we covered the release of ESP-WROOM-32 module datasheet, which promised that “New SDK features, tutorials and example applications will be released over the next few months.”.
The ESP-32 datasheet was released at the end of August. So let us discover the details of ESP-32 SoC.
ESP32 is a single 2.4 GHz Wi-Fi and Bluetooth combo chip available in QFN48 (6×6 mm) package. The new chip supports 802.11 b/g/n/e/i protocols with a data-rate up to 150Mbps. The previous ESP8266EX SoC supports 802.11 b/g/n only.
The security is enhanced in ESP32 by supporting WPA/WPA2/WPA2-Enterprise/Wi-Fi Protected Setup (WPS), while ESP8266EX supports only WPA and WPA2.
ESP32 features a BT4.2 controller and host stack with Xtensa Dual-Core 32-bit LX6 microprocessors up to 240 MHz. Keep in mind that ESP8266 has single core and lacks a bluetooth transceiver.
