Driver issues on Mac
Had to find legacy drivers for macOS to recognize the USB port. Once connected, the board works fine, but setup was frustrating.

Perfect for IoT Projects
Works great with Arduino IDE. The CH340 driver was easy to install on Windows. Wi-Fi connectivity is stable and the dual-core performance is noticeable.

Fast shipping
Board arrived well packaged in anti-static bag. Tested the blink example and it worked out of the box. Great addition to my lab.

Good value board
Functionality is solid for the price. The pinout silk screen is a bit faint so I recommend printing a diagram. Otherwise, no complaints.
