ESP32 DevKit V1 Buying Guide

Before buying an ESP32 DevKit V1, there are several hardware details worth checking.

ESP32 Chip

Verify which ESP32 variant is installed on the board. Different ESP32 development boards can use different chip variants even when they are marketed under similar DevKit names.

USB Interface

Check which USB-to-serial chip is used and which USB connector is provided. Common boards may use interfaces such as CP2102 or CH340.

Flash Memory

Many ESP32 DevKit V1 boards provide 4 MB of flash, but specifications can vary. Check the listing before purchasing if your project requires a specific amount of flash memory.

Pin Headers

Some boards are supplied with pin headers already installed, while others may require soldering. This can be an important consideration if you plan to use the board directly with a breadboard.
