Excellent Support
The community support for this chip is amazing. I was able to find libraries for every sensor I wanted to use. Boot times are fast.

Warm Operation
Functionality is fine, but it gets hotter than expected under continuous load. Make sure to provide adequate ventilation in your enclosure.

IoT Ready
Connected easily to my MQTT broker. The dual-core processing helps manage network tasks without blocking sensor readings. Very satisfied.

Good Value
Solid performance for the price. The pinout diagram could be clearer, but once configured, it runs smoothly. Gets slightly warm during heavy WiFi use.
