🚀 Best ESP32-S3 Development Boards
11 ESP32-S3 boards for Wi-Fi IoT, USB gadgets, cameras, displays and edge AI, from thumb-sized XIAO modules to 7-inch touch panels.
✅ 11 Picks Reviewed
✅ Native USB and PSRAM
✅ Camera, Display and Mini Boards
✅ Honest Pros & Cons
The ESP32-S3 is Espressif’s most capable mainstream Wi-Fi microcontroller: a dual-core Xtensa LX7 running at up to 240 MHz, 2.4 GHz Wi-Fi and Bluetooth 5 (LE), native USB that can act as a keyboard, mouse or serial port, vector instructions for TinyML, and support for large external PSRAM. That combination makes it the default choice for camera nodes, touch dashboards, voice assistants and any IoT project that has outgrown the classic ESP32.
This guide compares 11 ESP32-S3 boards that are live on Amazon, from official Arduino and Seeed boards to low-cost N16R8 DevKitC-style clones, a camera kit, display boards and M5Stack modules. If you need wired networking, see our ESP32 Ethernet and PoE boards, and for Thread or Zigbee look at the ESP32-C6 and H2 picks in our Matter and Thread development boards guide.
💡 Reality check before you buy: Not every “ESP32-S3” board is the same. Check the flash and PSRAM size (N16R8 means 16 MB flash and 8 MB PSRAM) and select the matching PSRAM mode in Arduino IDE or ESP-IDF, or camera and display code will fail. On N16R8 boards with octal PSRAM, a few GPIOs are reserved for the memory, so check the pinout before wiring. Boards with two USB-C ports have one for native USB and one for a USB-UART chip, and you may need to hold BOOT while plugging in for the first upload. The ESP32-S3 is a 3.3 V part and is not 5 V tolerant, so level-shift 5 V sensors. The S3 has no Thread, Zigbee or Wi-Fi 6 radio; pick an ESP32-C6 for those.

🔍 How to Choose an ESP32-S3 Board
🧠
Flash and PSRAM
Cameras, LVGL touch screens and TinyML models need PSRAM. N16R8 (16 MB flash, 8 MB PSRAM) is the safe default; 2 MB PSRAM boards are fine for sensors and relays.
📐
Form factor
DevKitC-style boards fit breadboards and expose the most pins. Nano and XIAO boards save space, castellated minis solder onto your own PCB, and M5Stack modules come in finished cases.
🔌
USB ports
Native USB enables HID keyboards and fast uploads. Boards with a second USB-UART port keep a serial console alive during resets and deep sleep, which helps debugging.
📶
Antenna
PCB and ceramic antennas are fine indoors. For a sensor in a metal box, garage or garden, choose a board with an IPEX connector and an external antenna.
🔋
Battery power
For portable or solar nodes, a built-in LiPo charger (XIAO ESP32S3) saves a separate charger board. Big displays and cameras draw too much for long battery life.

❓ Frequently Asked Questions
What does N16R8 mean on an ESP32-S3 board?
It is the module memory code: N16 is 16 MB of flash and R8 is 8 MB of PSRAM. In Arduino IDE choose “ESP32S3 Dev Module”, set Flash Size to 16 MB and PSRAM to OPI PSRAM, or the extra memory will not be used.
Why won’t my ESP32-S3 board upload code?
Try the other USB-C port, use a data cable rather than a charge-only cable, and hold BOOT while pressing RESET to enter download mode. If you use the native USB port, enable “USB CDC On Boot” so Serial output appears on that port.
Is the ESP32-S3 good for ESPHome and Home Assistant?
Yes. ESPHome supports the S3 for sensors, relays, Bluetooth proxies, displays and voice satellites. Add a mmWave presence sensor or a ToF distance sensor to build room and level sensors.
ESP32-S3 or Raspberry Pi Pico 2 W?
The S3 has more RAM options, faster Wi-Fi throughput, a camera interface and a mature IoT ecosystem. The Pico 2 W shines for precise PIO timing and very low cost. See our Raspberry Pi Pico kits guide to compare.
Can an ESP32-S3 run Matter?
Yes, Matter over Wi-Fi works on the S3 with Espressif’s ESP-Matter SDK. It cannot act as a Thread device because it has no 802.15.4 radio, so for Thread choose an ESP32-C6 or H2 from our Matter and Thread boards guide.
