ESP32 S3 Development Board ESP32-S3-DevKitC-1-N8R8 Wi-Fi and BLE | Cores Microcontroller Processor with ESP32-S3-WROOM-1 ESP32-S3 WiFi + Bluetooth BLE Functions MCU Module Dual Type-C Hat

Well worth it in fact purchased a a second module the next day

Works fine with espessif, I haven't tried it in the Arduino ide, has a learning curve for using the extra USB for UART but I got it going and no complaints there. I personally wish I got it without pre-soldered pins but they're clean joints. I used it with a CAN Bus adapter and that works fine with the adapters library. Typical esp32-s3 capabilities and was pretty cheap with good build quality it is larger than average boards but works the same.

For the price, I'm happy with this board. Solid specs. Let's keep it real though, this thing is cheap, like, might require a repair or two out of the box (see below), but that's the point. I wanted a cheap board to jump into a project with that could handle the stuff I want to run. For $8.99 I can handle a couple quirks. I had to bridge a solder pad for the RGB to work. It had solder, but there was a small gap. After checking continuity with a multi-meter and confirming the connections, it was a quick fix. Also, for anyone not able to flash the board after a while, do the following: 1. Unplug the board 2. Hold down the boot button 3. Plug it into your computer while holding down the boot button 4. Release the boot button 5. Flash To actually run the code, unplug the board and plug it back in. The board looks for some kind of enable signal to enter flashing mode, there's a way to do it besides the boot button, but I'm not sure how off the top of my head.

I really thought this would be a good introduction to ESP32. I’ve worked with the Arduino Mega before and was trying to upgrade to the ESP32. I bought this thinking it was a cheap and quality alternative to Espressif’s official boards. However, the trouble started as soon as I took it out of the box. This board is too wide and on a normal 5 pin breadboard, it is too big and leaves no pins available on one side while only leaving one row of pins on the other side. Please check the size before ordering. Additionally, I had so many problems setting it up in Arduino IDE and since there is literally no documentation to assist in this, it was a nightmare setting it up. I got it working though and the next problem was in regards to power. I was trying to power my LCD module which requires 5 volts through the 5 V in pin on the ESP but it just does not work at all. I realized that it was not communicating with the USB and that it is an input 5V only pin. So, I’ve decided to return this product and get the official ESPRESSIF ESP 32. I don’t think it’s worth the hassle just to save a few dollars when you can get the official one which has so much documentation.

This board has very little info. I thought mine was dead, but it turns out that while you can apparently flash it with the left USB port, only the right port will actually allow it to succeed and boot. The built in LED is very big and bright. It looks like it might be RGB but again there's no documentation on what pins anything's connected to so I haven't got it do do anything but turn on white so far.

This S3 is an upgrade from ESP32. It was a bit of a learning curve, but worked well when specifics were sorted. A great feature is that unlike ESP32 boards, the Reset button need not be held down when uploading sketch from IDE. Nice. Having a dedicated USB port is nice - but IDE still says it needs a USB MCU architecture and won’t support a USB library. Not sure if this is board-related or compiler related. Unfortunately after a week the USB ports no longer function and the device cannot be reprogrammed, though it still runs the installed code.

Cumple con las especificaciones y superó todas las pruebas diagnósticas que le realicé. Funciona perfecto :)
