  • So much bang for the bucks! Seeed has been great! Save yourself headaches!!!
Size: 3PCS Color: ESP32S3
These are crazy powerful and versatile MCUs. The form factor is fantastic. It's becoming more and more amazing how much they can pack into such a small board! I use a lot of Espressif MCUs from multiple vendors over the last few years. Most are fine but ...when I'm developing something new or need to know I have a well built device that will hold up and with great support...it's worth spending a few extra bucks. Seeed has been solid for a few years now. Never a dud....never a headache. They just work! The S3 is yet another fantastic version from the Espressif team. Seeed...knocks it out of the park! Get these and...you're project will work! You'll save time as well....not chasing cheap knock off issues! Get them!!!! ... show more

  • Small but mighty.
Size: 3PCS Color: ESP32S3
I really love working with these high quality processors. They allow my projects to be compact and they pack a lot of power in a small package.

  • I use a lot of these - Top quality MCUs
Size: 3PCS Color: ESP32S3
If you cannot solder, don't get these. They do require a soldering pencil to attach the pins. I have used these for many automation projects. Don't but because they are cheap. Do your research to see which fit your project scope. I picked Seeed studios because they have built in a LiPo battery charging circuit. I power then with external 5vdc or 3.3vdc but I always connect a battery in case there is a temporary power failure. I love the Over the Air software support that is available for these. In case you want to change the firmware, you can do it wirelessly without unhooking all your project from it. Truly revolutionary. Tons of IOT support. Free software to program it. Free development environment. Win, Win, Win. I have 4 in service in my home's automation. Only negative is they don't support Zigbee which I use other brothers in the Seeed studio chips. Another plus is their "sleep mode". If you use them much in for example solar projects. They can sleep using micro amps of power. The battery at this rate will not die for years. ... show more

  • I think these are a great product.
Size: 3PCS Color: ESP32S3
These work great! I have many ESP32s from Seeed Studio and I have not had a bad one yet. I have done Arduino, ESPhome and WLED projects. These really have not let me down and I have made audio streamer, mmWave, Infrared blasters, clocks with MQTT, spectrum analyzer. Even deep sleep and charging a lipo works. Wow. But honestly, if you're not in a hurry they can usually be purchased from Seeed Studio cheaper. ... show more

  • A tiny little powerhouse
Size: 3PCS Color: ESP32S3
Outstanding esp32. The s3 on dual core is crazy fast. I’m running spi, i2c, one wire LED controller controlling 40 rgb LEDs all at the same time from one esp32-s3. Not to mention WiFi mqtt comms and a pir sensor to turn off the oled when not in use. The form factor is super tiny. Leaves lots of room on pcb for other stuff. If I could change k e thing it wouldn be to support lifepO4 charging natively. Not just 1 cell lipo. But I’ve built several sensors for my home automation and air control monitoring using these ics and they don’t disappoint. ... show more

  • Highly recommended.
Size: 3PCS Color: ESP32S3
TL;DR You can't go wrong with XIAO ESP32S3. I never have any problems with these boards. I highly recommend them. PROS - Quality boards - Clear silk screening - Onboard battery charging (others don't have this) - Excellent documentation online CONS - There is no way to monitor battery life, they need to add an analog pad for reading this ... show more

  • Small footprint, good quality
Size: 3PCS Color: ESP32S3
There is a reason why Seeed product are very good. Very small footprint compared to other ESP 32 super mini designs has a built-in Lipo charging circuit so no need for a separate Lipo breakout board. Bluetooth external antenna connector comes in handy. GPIO pin holes are larger so you can use a 22 AWG wire Only one suggestion that I could make is to make the USB-C receptacle extend out for further from the board so you can put it in the housing directly. ... show more

  • Well made, trustworthy devices
Size: 3PCS Color: ESP32S3
These are packaged well and consistently work as expected. You can get slightly cheaper versions, but these actually work every time. That's worth more than saving a nickel. The external wifi antenna may be a pro or a con, depending on your intended use.
