About this item

  • 2.4GHz Dual Mode WiFi+Bluetooth Development Board: Built in ESP32-S chip, Xtensa single core 32-bit LX7 microprocessor, supporting clock frequencies up to 240 MHz. 128 KB ROM, 320 KB SRAM, 16 KB RTC SRAM. The chip supports secondary development without the need for other microcontrollers or processors
  • Compatible With Arduino+LoRa: The ESP32 development board is 100% compatible with the Arduino IDE, Lua, and Micropython. It is easy to develop and supports the LWIP protocol, Freertos, and three modes: AP, STA, and AP+STA
  • Advanced Peripheral Interfaces & Sensors: SPI, I2S, UART, I2C, LED PWM, LCD interface, Camera interface, ADC, DAC, touch sensor, temperature sensor, and up to 43 GPIOs. In addition, this series of chips also includes a full-speed USB On The Go (OTG) interface, which can support USB communication
  • Ultra Low Power Coprocessor (ULP): ESP32-S series chips support multiple low-power operating states, meeting the power consumption requirements for various application scenarios. The precise clock gating, dynamic voltage clock frequency adjustment, and adjustable output power of RF power amplifiers unique to chips can balance communication distance, data rate, and power consumption best
  • Unique Hardware Security Mechanism: The hardware encryption accelerator supports AES, SHA, and RSA algorithms. RNG, HMAC, and Digital Signature modules provide more security performance. Other security features include flash encryption and secure boot signature verification. A comprehensive security mechanism enables the chip to meet strict security requirements

I've tested two of these and both work as they should... I assume the third will as well.These are standard Wifi and Bluetooth ESP-32 development boards. They did not come with any documentation, but there is a ton online, so they aren't really necessary. They are faster than most standard Arduino boards and can be programmed with several different languages, such as C, Arduino or Micropython.The main reason I got these is that they can be programmed using a USB-C cable, which has become the standard... or at least is well on its way to being the standard. These are perfect for almost every project I regularly work on, and not having to shuffle between various USB cables is a plus!

These are great development boards, but I don't like this model because, 1) It uses micro USB versus USBC, 2) I have to hold the boot button while powering up to program it (unlike the USB C version which just programs when I send it a new upload). This one does have a port for an external 2.4 GHz WiFi antenna which I do like in some applications where the USB C version that I reference just has a cheesy build in WiFi antenna.

This is exactly what I expected from a ESP32 module. Nothing surprising, which is great when purchasing hardware.The range is what I would expect from a ESP32 module, so there doesn't seem to be any antenna design issues. The soldering looks fairly standard, so I don't expect any of the SMD of the leads to lose electrical contact.I use this to help make some of my LED strips "smarter" and it works amazingly well. There were no issues with programming the board. The leads can be stuck onto my breadboard without any issues.

I tried to use this chip with nanoFramework which is a c# development environment for ESP32 chips. It gave me all kinds of grief. Somehow the versions of the libraries this chip works with have some issues and anything related to the wifi will not build and run correctly. I have since ditched these chips for similar ones at DigiKey which cost a couple bucks more but they are solid and interface with nanoFramework well.

Fits on small breadboard (only Just), 1 pin on each side is clear to connect with the dev board.

Great little board. Using it for signal generation on the built in DAC and it worked well. Never left me guessing. Consistent loading of sketches!

I was never able to get the RGB to light up although an LED attached to pin 8 does work using Arduino IDE. The schematic shows no RGB LED in it nor does it show any CH340 USB chip. I never got Serial.println working with this board. If any one has facts to change my opinion I am all ears. Lastly, the USB port was mounted a bit crooked but the connections remained soldered so I was able to flash the board.EDIT: After buying this board and not being able to get RGB LED to light I bought an Espressif C3-Mini board. I was not able to blink its RGB LED with Arduino. I hunted down an tutorial for blinking RGB LED using ESP-IDF and found one on Instructables. I followed the instructions there and was able to get RBG LED to blink on both of these boards.The appearance of the manufacturing of the board still seems a bit sloppy but the seller offered me a refund (thank you for that) after this review first posted, so that is why I gave it four stars instead of just three.
