ELEGOO ESP-32 boards, pack of 3, USB-C review
A pack of three ESP-32 development boards with dual-core 32-bit processors up to 240 MHz, Wi-Fi and Bluetooth, USB-C and Arduino IDE compatibility, whose listing gives no memory or pin counts.
The bottom line A practical three-pack with the two details beginners need — USB-C and Arduino IDE — and few of the figures an experienced user compares. For learning and small networks of nodes it is enough.
The ELEGOO ESP-32 listing, bullet by bullet
Five bullets: a dual-core 32-bit processor up to 240 MHz; a low-power design with clock scaling for battery IoT devices; GPIO, SPI, I2C and other interfaces; 2.4 GHz Wi-Fi and Bluetooth; and over-the-air firmware updates.
Three boards in one ELEGOO box
A pack of three changes what a project can be. A sensor node, a receiver and a spare, or a small mesh of wireless devices, without ordering again. The listing’s title makes the count clear.
A beginner’s listing
USB-C and the Arduino IDE are exactly what someone starting out needs to know. Memory, pin counts and voltage are what someone designing a circuit needs, and those are left out.
Over-the-air updates
The fifth bullet describes updating firmware over Wi-Fi after deployment. For boards installed inside a device or out of reach, that saves opening the enclosure for every change.
Availability
At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 21 € to 25 €.
It is sold in the British Amazon store as well, in its own currency, which the euro figures above leave out on purpose.
The American Amazon catalogue lists the product, yet no seller was offering it.

Questions makers ask before buying
Can the ELEGOO ESP-32 boards be programmed with the Arduino IDE?
The title says the boards are compatible with the Arduino IDE.
Renesas RA4M1 (Arm Cortex-M4) with ESP32-S3 · Wi-Fi and Bluetooth 5.0 · USB-C · CAN and Qwiic · 12-bit DAC and op-amp · 12 × 8 LED matrix · Arduino IDE
An Arduino UNO R4 WiFi pairing a Renesas RA4M1 Arm Cortex-M4 microcontroller with an ESP32-S3 radio chip, with USB-C, CAN, a Qwiic connector, a 12-bit DAC and a 12 × 8 LED matrix on board.
Best for: A learner or maker who wants the Arduino ecosystem with Wi-Fi, and on-board feedback from the LED matrix.
ESP32-S3, up to 240 MHz, ULP coprocessor · 512 KB SRAM, 8 M PSRAM · 45 programmable GPIO · 2.4 GHz Wi-Fi and Bluetooth 5 LE · no logic voltage, USB or IDE published
An ESP32-S3 development board on the WROOM-1-N16R8 module, with Wi-Fi, Bluetooth 5 LE, 45 programmable GPIO and external PSRAM, whose listing names neither its logic voltage, its USB connector nor a programming environment.
Best for: A maker who already works with ESP32 boards and wants an S3 with extra PSRAM at a low price.
ESP32-S3 · CC1101 named in the title · external antenna · open-source hardware · documentation on GitHub and wiki only · no memory, pins, voltage or radios detailed
An ESP32-S3 device from LILYGO with a CC1101 named in its title and an external antenna, sold as open-source hardware whose five bullets contain links to documentation rather than specifications.
Best for: An experienced maker who already knows the T-Embed platform and will read the GitHub repository before buying.
