Ten years ago, “ESP32” meant one chip. Today it’s a family: the classic dual-core ESP32, the low-cost RISC-V ESP32-C3, the USB-focused ESP32-S2, the AI-capable ESP32-S3, the Wi-Fi 6 and Thread ESP32-C6, the dual-band ESP32-C5, the low-power Thread and Zigbee ESP32-H2, the display-and-video powerhouse ESP32-P4, plus the ever-popular ESP32-CAM camera board. They share a toolchain (ESP-IDF and Arduino-ESP32) but differ a lot in radios, memory and peripherals.
Picking the wrong chip is the most expensive mistake in an ESP32 project, more costly than picking the wrong board. So this hub starts with the chip: a comparison table, a “which chip for which project” guide, then the best board for each chip and a link to the full guide where we compare 8 to 12 boards per chip.
💡 The short answer: If you’re not sure, buy an ESP32-S3 board. It has Wi-Fi, Bluetooth LE, native USB, two cores and lots of memory, and it handles almost every hobby and prototype project. Choose the ESP32-C6 or C5 for Matter, Thread or Zigbee smart-home devices, the ESP32-P4 for big touchscreens and video, and the original ESP32 when you want the cheapest board with the most tutorials.

📘 Read the full ESP32-S2 guide (8 boards) → 🔍 What to Check on Any ESP32 Board
🧠
Flash and PSRAM
Codes like N16R8 mean 16 MB flash and 8 MB PSRAM. PSRAM matters for displays, cameras, Matter and anything TLS-heavy; simple sensors don’t need it.
🧱
Certified Module or Bare Chip
Boards built on Espressif modules (WROOM, MINI, SOLO) carry RF certifications and are the safer path to a product. Bare-chip boards are smaller and cheaper for prototypes.
🔌
USB-C and USB Wiring
Prefer USB-C. On S2, S3 and P4 boards, check whether the port goes to native USB, a USB-UART bridge or both; dual-port boards are the easiest to debug.
📡
Antenna
PCB antennas are fine on a desk. For enclosures, metal boxes, cameras and 5 GHz, look for a U.FL/IPEX connector and an external antenna.
⭐
Reviews and Documentation
Newer chips (C5, H2, P4) have few reviews on Amazon yet. Favor vendors with real documentation and examples, such as Espressif, Waveshare, Seeed, LILYGO, M5Stack and SparkFun.
❓ Frequently Asked Questions
What is the best ESP32 board for beginners in 2026?
An ESP32-S3 DevKitC-style board with 8 MB of PSRAM is the best all-round starting point, because it handles almost any project you’ll grow into. If you’re following older tutorials or want the lowest cost, an original ESP32 board like ELEGOO’s USB-C 3-pack is a great alternative. Set up your toolchain with our ESP-IDF installation guide and start with the getting started tutorial.
Which ESP32 is best for Matter?
The ESP32-C6 is the most popular choice, supporting Matter over Wi-Fi and over Thread on one chip. Use the ESP32-H2 for battery-powered Matter-over-Thread devices, and the ESP32-C5 if your Matter device must use 5 GHz Wi-Fi. Learn more in our Matter overview and Thread protocol guide.
Is the original ESP32 obsolete?
No. It’s still in production, still the cheapest dual-core Wi-Fi and Bluetooth chip, and the only ESP32 with Bluetooth Classic. For new designs, Espressif’s newer chips offer better security, USB and power efficiency, but the original remains an excellent learning and hobby board.
Do all ESP32 chips work with Arduino and ESP-IDF?
Yes, all nine are supported by ESP-IDF and the Arduino-ESP32 3.x core. The newest chips (C5, H2, P4) need recent releases, and a few third-party Arduino libraries still lag behind. ESP-IDF always gets new chip features first.
Which ESP32 has the best battery life?
The ESP32-H2 on Thread or Zigbee uses the least power, since it has no Wi-Fi. Among Wi-Fi chips, the C6 and C5 benefit from Wi-Fi 6 Target Wake Time and low-power RISC-V cores. Whichever you choose, deep sleep matters most; see our deep sleep tutorial.
🏁 Final Verdict: The Best Board for Every ESP32 Chip
Our top pick for each chip, with a link to the full guide:
Whichever chip you choose, the next step is the same: install the toolchain with our ESP-IDF guide for Windows or Linux, blink an LED with the GPIO tutorial, then build up to a web server and an MQTT client.
