Teyleten RobotESP32-S3-N8R2 ESP32-S3 Development Board Wi-Fi + BLE MCU Module Integrates Complete Wi-Fi and BLE Functions 3pcs

It's time to work

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

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).

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.

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.
