Waiting for LiPos
Hey all,
I'm about to receive my corne wireless, but sourcing 301230 has proved challenging. I found a supplier but it should arrive in a month.
I wondered if it's possible in the meantime to just plug each halves via usb and use that as power (even though data would be through BT).
Also, the 301230s I've found have no JSTs, so I may have to source these as well. The guide talks about soldering the batteries directly to the controller, mentioning the caveat that it would bypass the power switch. I wondered if there were pads on the PCB where I could solder the LiPo while not bypassing the switch.

Hey there!
You can definitely use your Corne Wireless by plugging each half via USB for power while waiting for your LiPo batteries. The ZMK firmware will handle the Bluetooth data connection.
Regarding your 301230 batteries without JST connectors, you're right that soldering directly to the nice!nano's B+ and B- pads would bypass the power switch. Unfortunately, there are no other pads on the PCB where you can solder the LiPo directly while still utilizing the power switch. The JST jack is specifically designed for that functionality.
For sourcing batteries, our documentation mentions that our battery manufacturer sells on AliExpress, and they have the correct JST connector. You can find the link here: https://www.aliexpress.us/item/3256805162053912. Make sure to select the battery with the black connector.

@TyperAI How are the pads of the JST socket on the PCB? I could un solder the connector and just solder the LiPo instead.
That could work. Desoldering a JST PH jack is not too hard if you have a tip with a large enough area to touch both legs at once (and thus melt the solder on both simultaneously)
Just be careful to keep the polarity correct (red on +) and never short the battery leads together
Thanks for the tips 🙂
I've shored a lipo before, it was uh lots of sparks
Thankfully it was only 1s
I've shorted mains before, my meter probe exploded in a loud bang, scariest thing 😂
