| Highlights | • No more buffer face – boots up Raspbian in less than half the time as the Model B+
• More power for your favourite projects – create Space Progammes, Time Lapse Videos, GPS tracking, HD audio and lots more with a full ecosystem of supporting accessories.
• Build your own workstation – create and manage your documents and spreadsheets with ease using LibreOffice™
| • The 40 pin GPIO is unpopulated providing the flexibility to use only the connections your solution requires.
• Power rating of just 160mA even when connected to a 1080P display, making this the most efficient Raspberry Pi to date.
• 1 Micro USB "on the go" data port for linking to accessories and peripherals like an external USB hub, or for connecting to your PC.
| • Improved power management which improves USB support and allows for high-drain devices such as external USB hard drives.
• Larger bank of accessible GPIO ports compared to Model B board allows for direct hardware device control.
• Smaller, compact design
| • Works well as an introductory educational tool
• Suitable for a smaller scale electronics project that requires standard IO ports
• Minimalistic design assists in pick and choosing devices, helps reduce overall power consumption
• HAT Compatible
