These little boards are like Sriracha, I put them in everything Read more

I had to do some significant googling to find a schematic that identified the pinout, but these work exceptionally well! The built-in antenna is great when you have minimal space to work with and the range is superb. The downside is that the pinout of these boards is NOT the same as with the XIAO ESP32C3, so you will need to plan your schematic/wiring accordingly, but I have used many different boards and knew beforehand that it wouldn’t be an exact drop-in replacement. These are a great value for the price and highly worth having a few on-hand! Read more

I'm a novice, but this literally isn't rocket science. Connect board, compile, it does a think. These boards have has so many random issues of error codes about being on the wrong port, detection issues, over heating. I'm pretty sure they're all dead. Sure that is a lot of processing power for your buck, but unless you're sure that you can get them working I'd pass. Read more

Bought in place of the XIAO C3 because it was cheaper and embedded antenna. Using for an out door WLED project. No issues at all. Slightly different pinout but everything working as expected. Read more

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. Read more
