Teyleten Robot ESP32-C3 Development Board ESP32 Supermini Development Board ESP32 Development Board WiFi Bluetooth 3pcs

Be aware if you intend to use LEDC instead of analogWrite for PWM, there are changes between expressif core versions, so LEDC use in V2.0.17 (last one for the older method I used) is way different than in V3.0.0 and up. There are 4 hardware PWM pins 0, 1, and 3,10 on the super Mini. There are channel numbers you can use for each hardware PWM, they can be configured differently if you wish. Use board ESP32C3 Dev Module, USB CDC On Boot Enabled under tools Sometimes it can be hard to get these into Boot mode where a port gets assigned to them. Like they say, press and hold Boot button down while briefly pressing Reset button, then release Boot button. I use this for a camera pan/tilt decoder (then a motor driver H bridge) for those IP cameras with a serial output. Works well. Nice small size fits in camera. Plus WiFi if i ever build a remote pan/tilt. Great value. Ease of use- well, takes some time to get used to them if you use LEDC. Also, servo library doesn't work, so you will have to use Expressf's native code for that function.

It's a bummer to see these boards only registering 4 out of 5 stars. They do come with some bum factory firmware on them, but once you update that they seem to be pretty good boards. I haven't run through all aspects of the board but it connects to WiFi pretty easily and gets decent range. It has the 4mb flash ram everyone loves, its GPIO pins function as expected and they're far cheaper than anything else I've seen on Amazon. I just bought another pack of them just to make sure I had them on hand if I ever need them. Maybe if your looking for the longest WiFi distance possible then the Xiao might be better for you with its external antenna, but... those are virtually double the price... So far these are working great, does get a little warm to the touch after operating for 15-30 minutes, not biggy for me though.

This esp 32 mini was very easy to use. The size was compact perfect for my use case. Using the device was as simple as plugging it into the usb port with Arduino ide. The Bluetooth and WiFi are very stable and easy to use. It draws little power and is very functional. The micro usb port is also very good

Wifi on these boards is TERRIBLE. The onboard chip design (red "c3") seems like a good idea, however it failed after 2 months of using ESPresense behind my TV. It worked great for a while and then just quit communicating with the Wifi WAP/Router, reverting to broadcasting it's own Wifi again. Another of the 3 I never could get any config to save. It says saving, but then after reboot, it's broadcasting default again. Only 1 still working but I think I'm going to trash it too and get the Seed boards. The heat on these is much cooler, no heat sink but the connectivity stinks.

Solid little boards. Consistent and worked well!

I've been using these in multiple projects which are mostly N scale model railway DCC, speedometer, sound decoder via ESP-NOW commands, etc. Like someone else said humorously "I put them in everything, like Sriracha sauce". My dev workbench is VS Code with Espressif ESP libraries and I've never had issues programming them. The WiFi is solid, too. I do wish that there was a battery backup version, though.

Great alternative to more expensive C3s when you're working on a project that might let the smoke out at some point. These are a "esp32-c3-devkitm-1" in PlatformIO. If you're using USB CDC for the serial monitor while debugging you might want to add a delay after you setup the serial. It takes these a second or two to start ACM and you might miss something otherwise.

Work great but make sure they can run what you need, some open source projects don’t support C3 boards yet.
