Teyleten Robot ESP32-C3 Development Board Core Board Serial WiFi Bluetooth Module WiFi+BTLE 5.0 Module Type-C for Arduino 3PCS

My board is slightly different from the one in the product picture, and from the one shown by another reviewer. It has a CH343 USB to serial adapter, which is probably able to use the same driver as the CH340, and some minor layout changes. When connected to either USB port, it boots to a sketch that lights up the neopixel in red, then green, then blue, then white. It doesn't appear to have MicroPython on it, as no drive shows up in Windows when connecting the board, no matter which port I use.Also, it appears to be programmed at least partially incorrectly, as when I run "Get Board Info" from the Arduino IDE, it says it's a WiFiduino32S3. I set the board type to "ESP32C3 Dev Module" and used the Adafruit NeoPixel strandtest example sketch as a test, and it worked.

Bought a pack to play around with the ESP32-C3 before integrating the chip into one of my own designs, can't beat it for the price. Full schematics are available if you search for the part number on the back of the board, but for the most part seems to be a clone of the DEVKIT boards. Mine came with MicroPython preinstalled, and they also work fine with PlatformIO+Arduino pretty much out of the box.Includes both a USB-C port connected to the C3's built in USB-serial interface (yep, just USB-serial and debug - it's not a full USB PHY like in the S2/S3), and a CH340 USB-serial interface chip connected to the C3's UART which is handy for debug prints on devices that are using deep sleep since deep sleep powers down the onboard USB.

They all work, were packaged well, and seem to have an identical pinout to the official Espressif ESP32-C3 Mini DevKit 1. They are too wide to use with a standard breadboard and have access to both sides (just one). My photos show it next to a compact version of a NodeMCU ESP32S designed for breadboards. Overall length with the antenna is nearly as long as my NodeMCU boards.The reason I cannot give them 5-stars is because they don't solder well. They just don't suck the solder into the joints like a quality board does. It takes a bit more heat and time to get an acceptable quality connection.The extra USB port is not an OTG port. It's a JTAG / Serial port. It is faster than the CH340K USB-Serial port, so I use that to do most of my work with this MCU.Note that the Arduino IDE requires some extra steps to use these boards. You must specify an additional boards manager URL to install Arduino ESP32 board support. You'll need version 2.0.0+ for RISC-V architecture support which the C3 is, unlike the ESP32/S2/S3. Select the "ESP32C3 Dev Module" board.
