Description

I have recently worked on some projects related to full keyboards, and I particularly like the keyboard on the BlackBerry, but it's hard to buy it, so I have decided to redesign it and try to make it more harmonious. Although it may not achieve the same level of comfort as the BlackBerry keyboard, it's worth a try. The board is mainly designed for learning interesting programming languages, so as to implement more interesting and fun applications. For the main controller, I still choose to design from RP2040, which is widely used.

A few days ago, I received the goods from PCBWay.

I am extremely grateful to PCBWay for sponsoring this project. Your generous support has been a tremendous encouragement and help to me. In the electronics manufacturing industry, PCB manufacturing is a crucial part, and PCBWay, as a leader in the industry, has always won the trust and praise of customers with its high-quality products and services.

PCBWay not only provides excellent PCB manufacturing services but also actively participates in community building, supports open-source hardware projects, and promotes the development of the electronics manufacturing industry. This sponsorship further demonstrates PCBWay's recognition and support for me, which makes me feel honored and grateful.

Here, I would like to express my sincere gratitude to PCBWay again and look forward to continuing to receive your support and cooperation in the future. With the help of PCBWay, I believe we can continue to make progress and achieve more innovations and breakthroughs.

I have used their SMT and 3D printing services, which are very convenient for double-sided welding and enclosure manufacturing, saving me a lot of trouble. The quality of the finished product fully meets my needs.

After powering on, I can normally burn the code. I have burned the CircuitPython firmware for the RP2040, which is very convenient for hardware debugging.

During the debugging process, I found some issues. Due to my mistake, I drew the wrong pin configuration for the display part and the packaging of the PCB, resulting in it not displaying normally. However, it's easy to fix, and I only need to reconnect a few wires to solve the problem.

The project are here.
