Reliable WiFi connection and kits with ESP32

Wireless Communication

Espressif designed and manufactured several WiFi/BT modules and development boards to help users evaluate functionality of the ESP32 family of chips. The chip itself and modules based on ESP32 chip gained huge popularity and the number of applications built on ESPRESSIF modules grow exponentially.

WROOM and WROVER Modules

This is a family of small modules that contain ESP32 chip on board together with some key components including a crystal oscillator and an antenna matching circuit. This makes it easier to provide an ESP32 based solution ready to integrate into final products. Such modules can be also used for evaluation after adding a few extra components, like a programming interface, bootstrapping resistors and break out headers.

Newly introduced WROVER modules include a 4MB pSRAM chip, thus targeting a wide variety of applications. The key characteristics of these modules are summarized in the following table:

Reliable WiFi connection and kits with ESP32

To speed up development process, Espressif offers a Devkit with ESP32 chip and USB/UART converter embedded for easy programming. The ESP32-DevKitC has signals break out on two headers. There are 38 pins available in total including 3,3V power supply, I2C, UART and GPIO signals.
The ESP32-DevKitC is breadboard friendly and developers can start to play with ESP32 module virtually immediately after unpacking.

Features of ESP32:

  • Two independently-controlled CPU cores with adjustable clock frequency, ranging from 80 MHz to 240 MHz
  • +19.5 dBm output at the antenna ensures a good physical range
  • Classic Bluetooth for legacy connections, also supporting L2CAP, SDP, GAP, SMP, AVDTP, AVCTP, A2DP (SNK) and AVRCP (CT)
  • Support for Bluetooth Low Energy (BLE) profiles including L2CAP, GAP, GATT, SMP, and GATT-based profiles like BluFi, SPP-like, etc
  • Bluetooth Low Energy (BLE) connects to smartphones, broadcasting low-energy beacons for easy detection
  • Sleep current is less than 5 μA, making it suitable for battery-powered and wearable-electronics applications
  • Integrates 4 MB flash
  • Peripherals include capacitive touch sensors, Hall sensor, low-noise sense amplifiers, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C
  • Fully certified with integrated antenna and software stacks
