Around 100mA. The voltage regulator can supply 150mA, but then the chip itself might draw up to 35mA...

Thank you Gordon,

Is VBAT directly routed to USB or Batterie ?

There's a bunch of info on the power supply circuit here: http://www.espruino.com/EspruinoBoard

It's routed via a 1 Amp thermal fuse, and in USB's case, a diode.

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

For syntax highlighting, surround the code block with three backticks:

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