A very powerful microcontroller with many features packaged in a small footprint.
These boards are so fun to add to projects. This is a 3 pack of the ESP32-S3 microcontroller each having 2.4GHz Wi-Fi, 5.0 Bluetooth capabilities. The board measures approximately 22.52mm by 18mm which make them a size perfect for adding within wearable technology or space limited projects. The boards contain 18 total pins (9 per side) including 11 GPIO pins, 1 Tx and 1 Rx pin along with a 3.3 Volt and 5Volt pins and 1 ground pin. The boards have a input supply voltage range from 3.3 volts to 6 volts, and if using a battery, you can use the B+ and B- pads on the bottom for the input voltage supply terminals. The boards are easy to program and include a USB-C port for programming. If you like working with microcontrollers or just with any IoT projects, you will enjoy these boards and be amazed at their capabilities with such a small footprint. Each board also has 2 pushbuttons onboard for boot and reset. I really like the quality of these boards and plan to order many more in the future. At the time of this review the 3 pack was priced under $19 USD, which make each board less than $6.50 USD. There is also a 10-pack option available too.

Absolutely terrible, other boards work, THESE DO NOT.
Unfortunately every one was bad. No com port found, or, if it was, the constant ‘didledoo’ sound of it constantly trying to reconnect on a windows computer. Tried multiple ports, multiple cables… my other esp32 modules work fine, so this is a crappy batch, and the company DOES NOT DO ANY QUALITY CONTROL OF ANY VALUE…. or they are outright scammers.

🧠 Tiny but Mighty—Perfect for Compact IoT Builds with USB-C Convenience
The 3PCS SuperMini ESP32-S3 Development Board from Meshnology is a fantastic option for makers, developers, and tinkerers working on space-constrained IoT or wearable projects. These boards pack serious performance into a footprint smaller than a postage stamp 📦⚙️.🚀 Performance & ConnectivityPowered by a 32-bit RISC-V CPU running at 160 MHz, the ESP32-S3 handles everything from basic sensor polling to more complex edge processing tasks. Wi-Fi (802.11 b/g/n) and BLE 5.0 work reliably, making it ideal for wireless applications like smart wearables, remote sensors, or BLE beacons 📡🔗.🔌 USB-C Interface = Huge WinUnlike many micro boards that require external programmers, this one includes a built-in USB-C connector for flashing and power. That’s a major convenience—no need for breakout boards or FTDI adapters. Just plug it in, and you’re ready to go. It also makes development faster and more beginner-friendly ⚡🧰.📏 Form Factor & DesignAt just 22.52×18mm, these boards are impressively compact. The single-sided surface mount layout is clean and easy to integrate into tight enclosures. Despite the size, the solder pads are well-labeled and accessible for prototyping.🔌 Interface OptionsYou get 11 GPIOs (PWM capable), 4 ADCs, plus UART, I2C, and SPI—all the essentials for connecting sensors, displays, or other modules. The onboard RGB and blue LEDs are a nice touch for status indication or visual feedback during development 💡.🔐 Security & StabilityAES-128/256 hardware encryption and secure boot support make this board suitable for projects where data integrity matters. It’s reassuring to see these features included even in such a small form factor 🔒.🧪 Use Case ReadyI’ve tested one in a low-power wearable prototype and another in a BLE-enabled sensor node. Both performed flawlessly. Power consumption is minimal, and the boards stay cool even under load. Arduino and MicroPython compatibility means setup is fast and flexible 🛠️🐍.⚠️ Minor Notes• Documentation is decent but could be more beginner-friendly.• Be mindful of the “P76 battery” mention—it’s likely a placeholder or irrelevant to this board’s actual power setup.✅ Final VerdictIf you’re building compact, connected devices and need a reliable, low-power microcontroller with rich I/O, wireless capabilities, and USB-C convenience, this 3-pack is a smart investment. Great for pros and hobbyists alike 🔧📲.

Compact and Capable ESP32 Boards for DIY Projects
I picked up these tiny ESP32 boards for some small DIY projects and have been pleasantly surprised. They’re compact enough to fit into tight spaces without feeling cramped, yet still provide reliable Wi-Fi and Bluetooth connectivity. The low power draw really stands out, especially for battery-powered projects, and the layout makes it easy to experiment with different peripherals.My main complaint is the lack of documentation. I had to search online to figure out some pin functions, and soldering the headers wasn’t exactly plug-and-play. Once set up, though, they run smoothly with both Arduino and MicroPython. Overall, these boards are a solid little workhorse for anyone exploring IoT, wearables, or compact electronics projects.

Cheap and borderline useless, hit and miss
At least one arrived broken. Several exhibit extremely poor wifi range, most likely due to garbage ceramic antenna. Trying to find a working mod but it’s starting to become a waste of time. Should have gone with Xiao’s ESP32C3, cost more but works flawless.Update 8/16/25: Bumping to 3 stars as I found two viable workarounds for the WiFi / Antenna flaw with these boards. 1 – setting wifi tx power to 8.5dBm WiFi.setTxPower(txPower); 2 – leaving pin 21 unsoldered and disconnected; Either of those allows reliable wifi connection. For first method I am still testing how range is affected but so far no issues. I tried various other antenna mods, none worked. For the price of sub $3/unit it is worth the trouble.

Excellent Value on Powerful, Compact Dev Boards
This 3-pack of SuperMini ESP32-S3 development boards is a fantastic find for anyone working on compact IoT projects. Their incredibly small size makes them perfect for applications where space is limited, like wearable devices or discreet sensor nodes. Despite their small footprint, they are very powerful, featuring the ESP32-S3 chip with its reliable WiFi and Bluetooth 5.0 connectivity. They are compatible with both the Arduino IDE and MicroPython, which makes them very accessible for developers. The onboard RGB LED is a nice little bonus for status indicators. Getting three of these capable and tiny boards in one package is excellent value, perfect for building multiple projects or just having extras on hand.

Ich habe mich für den ESP32-S3 super mini entschieden, da die S3 Version einen Laderegler für Akkus integriert hat. Von den bestellten 6 Stück funktioniert nur einer mit Akku, bei den anderen 5 Stück liefert der Spannungsregler aus dem Akku statt den Benötigten 3.3V nur 2.5V und ist damit für den Anwendungsfall der Nutzung mit Akku unbrauchbar.
