Choosing the best ESP32 board is confusing, because there are dozens of versions with similar names. In this guide we compare the boards we actually recommend for home automation, sensors and maker projects, explain the differences in plain English and tell you which one to buy for each type of project.

The Best ESP32 Boards for Every Project
1. ESP32 DevKitC (ESP32-WROOM-32) – Best for beginners
The original ESP32 and still the safest first board. It has Wi-Fi, classic Bluetooth and BLE, two cores, plenty of GPIO pins and the biggest collection of tutorials, libraries and ESPHome examples. If a guide online says “ESP32”, it almost always means this chip.
- Great for: Learning, home automation sensors, ESPHome, Arduino projects
- Keep in mind: Older chip, no native USB (uses a USB-to-serial adapter), higher power draw than newer models
2. ESP32-S3 DevKitC-1 – Best all-rounder
A faster, more modern ESP32 with native USB, AI vector instructions and versions with extra PSRAM. It is ideal when you need a display, a camera or more memory, while still running the same Arduino and ESP-IDF code.
- Great for: Displays, cameras, voice and small AI projects, USB devices
- Keep in mind: No classic Bluetooth (BLE only), more expensive than the basic ESP32
3. ESP32-C3 (DevKitM / SuperMini) – Best cheap and small
A tiny, low-cost single-core RISC-V chip with Wi-Fi and BLE and native USB. It is perfect for simple sensors that report to Home Assistant, where you do not need the power of a dual-core chip.
- Great for: Small sensors, battery projects, cheap Wi-Fi nodes
- Keep in mind: Fewer GPIO pins, single core
4. ESP32-C6 DevKitC-1 – Best for smart home (Thread/Zigbee)
The C6 adds Wi-Fi 6 and an 802.15.4 radio for Thread and Zigbee, which makes it interesting for Matter devices. If you want to future-proof a smart home project, this is the one to look at.
- Great for: Matter, Thread and Zigbee devices, Wi-Fi 6 networks
- Keep in mind: Younger ecosystem, fewer tutorials than the classic ESP32
5. Seeed Studio XIAO ESP32-S3 / C3 – Best tiny board
A thumb-sized board with USB-C and a battery charging circuit on some versions. Great when space matters, for example inside a wearable or a small 3D-printed case.
- Great for: Wearables, compact enclosures, battery projects
- Keep in mind: Few pins, small antenna, pricier per pin
6. ESP32-CAM (AI-Thinker) – Best budget camera
A very cheap board with a camera module and a microSD slot. It is a fun way to build a Wi-Fi camera, a doorbell snapshot or a time-lapse, although it needs a separate USB adapter to program.
- Great for: Wi-Fi cameras, time-lapse, simple image projects
- Keep in mind: No USB on the board, can be unstable with weak power supplies
7. LilyGO T-Display-S3 – Best with a built-in screen
An ESP32-S3 with a color display already attached, plus buttons and battery support. It is the quickest way to build a small dashboard, a clock or a status screen without any wiring.
- Great for: Dashboards, clocks, info screens
- Keep in mind: Fewer free pins, specific libraries for the display
How to Choose the Right ESP32 Board
- Just learning? Start with the classic ESP32 DevKitC. Most tutorials, including ours, use it.
- Need a screen or camera? Choose an ESP32-S3, ideally a version with PSRAM (for example “N16R8”).
- Running on batteries? Look at the ESP32-C3 or a XIAO board, and use deep sleep.
- Building Matter or Zigbee devices? Go for the ESP32-C6.
- Check the USB port. Boards with native USB or USB-C are easier to flash and avoid driver problems.
New to microcontrollers? Read our first Arduino project guide, because the same ideas apply to ESP32, and compare boards in Raspberry Pi vs Arduino. You can also calculate resistor values with our free LED resistor calculator.
What Else You Need
- A good USB data cable, not a charge-only one. See cables →
- A breadboard and jumper wires for prototyping. See kits →
- A sensor kit to experiment with temperature, motion and light. See sensor kits →
- A 5V USB power supply for permanent installs. See power supplies →
Frequently Asked Questions
Which ESP32 is best for beginners?
The classic ESP32 DevKitC with the ESP32-WROOM-32 module. It is cheap, well documented and works with almost every tutorial, Arduino library and ESPHome example.
What is the difference between ESP32 and ESP32-S3?
The ESP32-S3 is newer, has native USB, AI instructions and versions with more PSRAM, which makes it better for displays and cameras. However, it only supports Bluetooth Low Energy, not classic Bluetooth.
Is ESP32-C3 good for Home Assistant?
Yes. The ESP32-C3 works with ESPHome and is a great low-cost choice for simple Wi-Fi sensors that report to Home Assistant.
Which ESP32 supports Zigbee and Thread?
The ESP32-C6 (and the ESP32-H2, which has no Wi-Fi) include an 802.15.4 radio for Zigbee and Thread, which is useful for Matter devices.
Do I need an ESP32 with PSRAM?
Only for memory-hungry projects such as cameras, large displays or audio. For simple sensors, a board without PSRAM is enough.
