接続は、PC-8001本体後ろの拡張端子に接続しますが、50pフラットケーブルでの接続、50pカードエッジコネクタでの接続のどちらかを選択できます。

注2)秋月電子通商 AE-microSD-LLCNVのJ1ジャンパはショートしてください。

注5)ピンヘッダで代用するときは、基板から若干浮かせてピンヘッダをハンダ付けするとフラットケーブをスムーズに抜き差しできます。

MicroSD Card Adapterについているピンヘッダを除去してハンダ付けするのが一番確実ですが、J4の穴にMicroSD Card Adapterをぴったりと押しつけ、裏から多めにハンダを流し込むことでハンダ付けをする方法もあります。なお、この方法の時にはしっかりハンダ付けが出来たかテスターで導通を確認しておいた方が安心です。

PC-8001 SD: common questions

What microcontroller does the PC-8001 SD use?

The PC-8001 SD is built around the Arduino_Pro_Mini_5V, from the AVR/Arduino family.

How big is the PC-8001 SD PCB?

The PC-8001 SD measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PC-8001 SD?

19 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the PC-8001 SD design files?

From the yanataka60/PC-8001_SD repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PC-8001 SD design in my own project?

Yes, under the terms of its MIT license, which yanataka60 chose for the repository.

Can I test firmware for the PC-8001 SD without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
