Review: ESP32 development board

The ESP32 is the ESP8266 successor. The ESP32 is loaded with lots of new features. It combines Wi-Fi and Bluetooth wireless capabilities, and it’s dual core.
ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power-management modules.

Engineered for mobile devices, wearable electronics, and IoT applications, ESP32 achieves ultra-low power consumption through power saving features including fine resolution clock gating, multiple power modes, and dynamic power scaling.
What to look for in ESP32 Breakout Boards
There are several things that you should check for when purchasing an ESP32 breakout board. One of those things is the pin configuration of the board. To be able to utilize all the features of the ESP32 chip you need access to all its pins. Therefore, confirm whether the pin spacing and layout of the breakout board are compatible with the rails of a breadboard. In other words, is the pin configuration breadboard-friendly?
Another thing to check out for is the additional circuitry on the board. The ESP32 chip needs some extra circuitry for it to be programmed and powered successfully. This circuitry is usually available on the breakout board. You should make sure that the ESP32 breakout board has a USB-to-UART interface, a voltage regulation circuit and access to the reset and boot features preferably via pushbuttons.
Those are some of the considerations you should make when selecting an ESP32 board. If your breakout board meets the above requirements you will be assured of a fast and successful project development process.

How to Select an ESP32 Development Board

Pin configuration and number of pins
To properly use the ESP32 in your projects you need to have access to the board pinout. Make sure you have access to the board pinout you’re getting. Otherwise, you may end up using the ESP32 incorrectly. We recommend taking a look at our ESP32 GPIO Reference Guide that shows how to properly use the ESP32 GPIOs.
USB-to-UART interface and voltage regulator circuit
Most full-feature development boards have these two features.

BOOT and RESET buttons
When selecting an ESP32 development board always look out for those with Boot and Reset buttons.

Battery connector
If you want to power your ESP32 using batteries, there are development boards that come with connectors for liPo batteries.

Extra features
There are ESP32 development boards with extra features like an OLED display, a LoRa module or a camera.

If you have a really specific project in mind, then maybe one of the other models is more suitable for you. For example, if you intend to add an OLED display to your project, the ESP32 with built-in OLED will provide all you need in a small footprint.
