Teyleten Robot ESP32-S3-N8R2 ESP32-S3 Development Board Wi-Fi + BLE MCU Module Integrates Complete Wi-Fi and BLE Functions 3pcs

Items arrived as described, easy to setup and program, work great.

Everything works exactly the same on this board as the Espressif official development board, at half the price! The pinouts of these two boards are also the same, however this board (Teyeten Robot) has a 0.1" wider pins stance than the official board, or one hole wider on a breadboard. The only issues that I ran into was the need to download the CH341SER drivers to allow Arduino IDE / PlatformIO / ESP IDF to communicate to the board via Serial USB. Other than that, everything was a breeze to set up and use. The onboard JTAG USB debugging is a life saver and is much easier than having to use a dedicated ESP-PROG debugging tool. Overall, great product that I would highly recommend! All 6 boards that I have used and tested were perfect. Looking forward to getting more development boards in the future from this company... you just can't beat their pricing.

High quality and an excellent deal, just one minor defect: The ESP32S3 doesn't reliably boot when power is applied / after programming. The root cause is an extra 0.1uF capacitor on the BOOT signal which causes it to stretch beyond the EN signal resulting in the chip getting stuck in UART bootloader mode. The fix is to de-solder the small 0.1uF cap next to the BOOT button. This then matches the official ESP32S3 reference schematics and results in a reliably booting board. Despite what other reviews say, the USB-to-serial chip on this board is fully supported by Windows (driver auto installs with Windows Update) and Linux (built-in kernel driver).

It took me a while to figure this all out. Hope this helps you. From factory, it comes with flash all blank. Needs to have circuitpython and/or bootloader installed. It has 2 usb ports. One is labeled "com" and the other "usb." First connect to the "com" port, and use esptool.py to flash the "combined.bin" UF2 bootloader, that is downloadable from the circuitpython download page for this device. Then swap the cable to the "usb" port, and the UF2 bootloader will make a removable drive available to your computer. Copy the circuitpython UF2 file, which is also downloadable from the circuitpython site for this device. The device will reboot, and you'll have the full circuitpython experience. If you need to re-flash at a later time, to upgrade circuitpython, press Reset, and then quickly while the light is purple, press Boot. This will take you to bootloader mode, which will allow you to replace the circuitpython UF2 file.

This Teyleten Robot ESP32-S3 development board pack offers great value for hobbyists and developers alike. With Wi-Fi and BLE capabilities, it's incredibly versatile for a range of IoT projects. The compact size and easy-to-use design make it a solid choice for beginners and experienced users. While the documentation could be more extensive, the online community provides ample support. Overall, a good option for those looking to experiment with the ESP32-S3 platform.

This board is fantastic! Ample GPIO and the 5V pin is a true in. I've had to use diodes on some other boards to keep the 5V or vsys pin from outputting 5V. This is great is you want to control a set of neopixels. The onboard neopixel is also a fantastic addition. When using the board keep in mind that only one of the USB-C ports gives you serial and drive access for circuit python and for flashing the board.

There is absolutely no schematic diagrams or any documentation for the board it may be low cost but it is pretty useless unless you have some documentation there is no way to tell what is wired to what in reality it is a waste of money. Also they have the USB connectors labeled wrong which is not surprising.

The boards work, and seem okay on 3v. I had some issues and wasted many ours trying to troubleshoot GPS and mmwave sensors. running 5v I had tried 1k on the RX but pin was still over loaded and not reading. touching the wire seemed to give it enough capacitance to get data, but it was still problematic. 10k leg and self grounded I was finally able to get data from GPS and mmwave 5v sensors. I wanted these for the live debug and serial separation. but then found they do not fit the standard expansion boards. not sure I will have much use for them.

I've been abusing these little boards for a few weeks now and they're still going strong. These units have some added QoL like 2 USB ports, USB-OTG one scratch enable, lots of pins. Good units

If anyone is look the RGB LED is on pin 48 not 38
