Is it possible to safely connect my Pocket Reform internal keyboard to an external USB host for development? If so, do I need something like a Unified Daughterboard or can I just connect the J2 JST PH connector directly to an external USB host with something like this cable? For development only …
In that case the shield is connected to the external host only — not to the Pocket or the keyboard. Is it possible to do this safely?
Can you confirm the wire colors of the Pocket Reform internal USB cable are reversed? I haven’t yet checked my own laptop but in the Assembly Manual they look like
| Pin | Name | Wire color |
|---|---|---|
| 1 | +5V | Black |
| 2 | D- | Green |
| 3 | D+ | White |
| 4 | GND | Red |
In this listing the wire colors at the JST PH end look like they match those of the internal USB cable? but that’s the wrong polarity, if the USB A end has normal wire colors?
The wire colors of these cables in the Pocket Reform are indeed “random” and your pinout is correct.
Awesome thanks @minute! If I’m careful, is it possible to completely remove the keyboard from my Pocket Reform and connect it to an external USB host for keyboard firmware development?
