Other accessories, optional but helpful for general Pi development:
- 802.11b/g/n USB WiFi adapter (If you have older model Pis without built-in WiFi, it can be useful to be able to switch between wired and wireless depending on your proximity to a network jack!)
- 5mm Diffused RGB LEDs (great for showing status!)
- Assembled RPi GPIO Cobbler with 40-pin cable (helpful for prototyping)
- Half-size breadboard
- Breadboard/prototyping jumper cables
