Great tiny board
Works perfectly for my IoT sensor project. Easy to flash and the WiFi range is surprisingly good for the size.

Compact but powerful
Pins are a bit tight for standard breadboards but manageable with jumper wires. Performance is excellent.

Good value
Wish it had a battery connector built-in, but otherwise a solid development board for the price.

Perfect for MicroPython
Setup was straightforward on Windows. MicroPython runs smoothly with the available PSRAM.

Excellent WiFi range
Better than the old ESP8266 boards I used previously. The S3 chip handles multitasking well.
Q: Does this board support 5V logic levels on the GPIO pins?
A: No, the GPIO pins operate at 3.3V logic levels. Applying 5V directly may damage the board.
Q: What USB driver is required for Windows?
A: It typically uses the CH343 or CP210x driver. Please check the specific batch documentation on our wiki.
Q: Is there an external antenna connector available?
A: No, this model uses an onboard PCB antenna. There is no connector for an external antenna.
Q: Can I power this directly from a LiPo battery?
A: Not directly on the 5V pin without regulation. We recommend using a dedicated battery module or regulator circuit.
Q: Can I program this using the Arduino IDE?
A: Yes, it is fully compatible with the Arduino IDE. You will need to install the ESP32 board manager package.
