While micropython certainly isn't my preferred way to do it, it is actually nice, I'm enjoying it, and it's not like I have a choice :) I am obviously connecting via microUSB.

The Pi Pico datasheet recommends a maximum power draw on the 3V3 pin (pin 36) of 300mA.

This example makes a USB hid host application.

This makes it incredibly versatile when it comes to incorporating the Pico into projects where power demand can easily vary between modules.
I am considering a design where I would draw around 1A on the 3V3 rail.

driving an LED, on-board Switched Mode Power Supply (SMPS) power control and sensing.
To automatically run a MicroPython program, simply save it to the device with the name main.
One Pico acts as a USB HID keyboard device for the computer and another acts as the USB host to read inputs from the keyboard.
I'd like to use MicroPython on the Pico to communicate (bidirectionally) with a Python program on another host (iMac or RPi).
