1. PCBのサポート部分を折り取ります。折った部分のデコボコが気になる場合はやすりなどで削ってください。 1. ソケットをはんだ付けします。 MXスイッチ用のソケットは上側、Chocスイッチ用のソケットは下側に設置します。 印刷に合わせて、スイッチの穴を塞がないようにします。 1. TRSコネクターをはんだ付けします。 ずれやすいのでテープなどで固定してください。 1. ファームウェアのファイル(.uf2)をダウンロードします。 https://github.com/tamaroh/maggie42cs/releases/tag/V2.0.2 1. (片側ずつ両方とも)USBケーブルを接続して、以下のいずれかの方法で RPI-RP2 リムーバブルドライブをマウントさせます。 1. BOOTSELボタンを押しながら、USBケーブルを接続します。 1. USBケーブルを接続してから、BOOTSELボタンを押しながらRESETボタンを押します。 1. 左側はTABキー、右側はYキーを押したままUSBケーブルを接続します(キースイッチ装着済みの場合)。…

Pcb l: common questions
What microcontroller does the Pcb l use?
The Pcb l is built around the RP2040, from the RP2040/RP2350 family.
How big is the Pcb l?
The Pcb l measures 128.6 × 95.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pcb l?
80 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pcb l design files?
From the tamaroh/maggie42cs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pcb l design in my own project?
The repository has no license, so all rights stay with tamaroh. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pcb l without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
