What is the maximum current that the 3V3OUT pin can supply? I have a Pico Pro/Max.
Thanks in advance !

Hello, the hardware has a redundant design. If you use the computer's USB 2.0 port for power supply (5V, 500mA), the maximum current supported at 3.3V is 450mA. If the load is too large, it is recommended to use an external power supply.
