Picochu

I am planning on powering the Pico from a computer's PSU molex 5v line. I cannot find any consistent info on the Amps that come from it. Point being, I need to figure out the right resistor to use on that line. Has anyone done this before? @Gordon, any thoughts?

I'm not sure you need a resistor? Espruino should run off 5v without needing anything in-line?

Alrighty, was just making sure I won't blow it up. I supposed it will draw as much amperage as it needs as long as that line can supply it

It'll be fine, as long as you don't wire it up backwards or anything :) It should only draw max ~30mA, and usually less if it's entered sleep mode.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

Just like Github, a blank line must precede a code block.
