Good board, steep learning curve
Hardware is solid but documentation could be better for beginners. Once set up, it runs well.

Great Dual-Band Performance
Works flawlessly with Ameba IDE. The 5GHz connection is stable and speeds are good for data logging.

USB-C is a lifesaver
Finally no more micro-USB cables. Programming is fast and reliable with the included cable.
