Still in waiting mode... the Keyboard connector breakout boards have been ordered from JLCPCB and they shipped yesterday so they just have to make thier journey across the ocean to my door. I've also ordered 10 of the special connectors from Digikey and those are on the way too.
On Friday I also received my solder reflow plate, yay! I used it to remove some random surface mount components from an old hard drive PCB and it worked like a dream, I can't wait to start using it.
Oh, I also ordered a Raspberry Pi Pico (RP2040) from Digkey as well. Although I have 2, the Atmega processor I've been planning on using as they keyboard controller is pretty much unobtainium at the moment, and right now it's actually more expensive than an RP2040.
I'm waiting for the following right now:
* Solder Paste - Aliexpress
* PCBs - JLCPCB
* Keyboard Conector - Digikey
* Raspberry Pi Pico - Digikey
Once I get those parts the next step is to build a prototype working USB keyboard with the BBQ10 keypad. Fun on the bun.
