andicelabs / powercape Goto Github PK

Hello, your website is down, so I am hopefully contacting you here

I acquired an old power cape, and am trying to figure out how to acquire or construct a power supply.

As I understand it, the charge port for the board is a Molex MicroFit (2 circuit) connector, and I am not supposed to use the standard 5V connector on the BBB. I already have a new battery connected to the JST port.

So, I can acquire a Microfit cable but then I have to somehow connect the other end to maybe a USB or wall plug, something like that. So I would have to splice my own cable. I talked to Molex about it and they didn't have any specific products nor recommend trying to make my own (theirs is Microfit to Microfit, or Microfit to bare wire).

What would you use for a power supply? Do I create my own cable?

Or if I were to buy a USB header for the opposite end of the microfit cable, would it work? If I crimp my own cable, what should I take note of?

Will I fry the cape if I plug in the 5V power while I wait to figure this out?

A bad "set I2C address" command can make the cape inaccessible over I2C.

When building powercape.c and ina219.c for Beaglebone Black running a Resin.io Debian container, I had to change int i2c_bus = 1; to int i2c_bus = 2; as the devices were on the i2c-2 bus instead of the i2c-1 bus.

I have a patch if you want to make the fixes programatically (git apply fix_powercape.patch).

I see the www.andicelabs.com web site is no longer working. Have you posted the schematics and pcb layout files? I think I read a blog post on your website a month or two ago where you mentioned you were planning to do so. I am not sure if they will be posted to a repo on your Github account or somewhere else?

What license is this code under? Can you please put a LICENSE file in the repository or otherwise specify the license? Thanks.
