# Nano Ardule PCB 설계 튜토리얼

이 문서는 Nano Ardule MIDI Controller를 예제로 KiCad 학습을 진행하는 방법입니다.

---

# 1. 프로젝트 생성

KiCad → New Project

---

# 2. Schematic 작성

Add Symbol

다음 부품 추가:

Arduino Nano  
6N138  
74HC14  
DIN MIDI connectors  
LCD header  
Encoder header  
Switch  
LED  
microSD header

---

# 3. MIDI IN 회로

DIN
→ 220R
→ 6N138
→ pull‑up
→ 74HC14
→ Arduino RX

---

# 4. MIDI OUT 회로

Arduino TX
→ resistor
→ DIN connector

---

# 5. LCD 연결

I2C

A4 → SDA  
A5 → SCL

---

# 6. Encoder

Pins:

CLK  
DT  
SW

---

# 7. microSD SPI

D10 → CS  
D11 → MOSI  
D12 → MISO  
D13 → SCK

---

# 8. Footprint 할당

Example:

6N138 → DIP‑8  
74HC14 → DIP‑14  
Switch → 6mm tact
