Logic level & voltage
Logic level is 3.3 V (per the board specs). Power from 5 V on VBUS or 1.8-5.5 V on VSYS; GPIOs are not 5 V-tolerant. Adds onboard 2.4 GHz Wi-Fi over the base Pico.
Typical uses
- Wi-Fi IoT and web-controlled projects
- MQTT / HTTP sensor nodes
- Networked PIO interface projects
Wiring notes & gotchas
- GP23/24/25 and the WL_GPIO lines are tied to the wireless chip — don't reuse them.
- ADC pins are 3.3 V max.
- Level-shift 5 V peripherals.
