It has been a while from the announcement of the new SoC ESP32 from Espressif.
Recently, Espressif released the ESP-WROOM-32 module which is based on ESP32 SoC, the big brother of the well know ESP8266 WiFi module.
ESP32 is a 2.4 GHz Wi-Fi and Bluetooth combo chip with dual CPU cores and a very rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, low noise sense amplifiers, SD card interface, Ethernet, high speed SDIO/SPI, UART, I2S and I2C.
The datasheet of ESP-WROOM-32 module contains pin definitions, functional description, electrical characteristics and a schematic.
ESP32 contains two low-power Xtensa ® 32-bit LX6 microprocessors with 448 KBytes ROM and 520 KBytes on-chip SRAM for data and instruction and supports 4 x 16 MBytes of external QSPI flash and SRAM.
It has various power modes. A 160 ~ 260 mA power consumption for Wi-Fi Tx packet @ 13 dBm ~ 21 dBm.
“New SDK features, tutorials and example applications will be released over the next few months.” according to the datasheet.
