EXAMPLE
EAGLE DEMO
EXAMPLE
Throughole vs SMD
PROGRAMMING
Tiny AVR Programmer• Super easy to use • Well supported from Arduino IDE • Only about $20 on SparkFun
PROGRAMMING
Arduino as ISP• Just use your existing Arduino! • Well supported from Arduino IDE • Re-program a chip you’ve already
soldered to your PCB
RESOURCES
Parts • SparkFun • Adafruit
PCB Fabrication • OSH Park • Seeed Studio
Tutorials • SparkFun: Using Eagle
