Pros
- Wi-Fi + Bluetooth for $6
- Same friendly Pico ecosystem and PIO
- Official, well-written MicroPython networking docs
Cons
- Wi-Fi 4 only, a single band, modest range
- Deep-sleep current is high compared with ESP32 / nRF
- LED is wired through the radio chip, not a normal GPIO
Best use cases
- 01Wi-Fi sensors with MicroPython
- 02Simple web servers and dashboards
- 03MQTT / Home Assistant nodes
- 04Wireless LED controllers
