Versionen från 27 februari 2013 kl. 13.42
Raspberry Pi är en enkortsdator baserad på en ARM SoC CPU.
| Model A | Model B | |
|---|---|---|
| SoC: | Broadcom BCM2835 (CPU, GPU, DSP, SDRAM, 1x USB port) | |
| CPU: | 700 MHz ARM1176JZF-S core (ARM11 familjen) | |
| GPU: | Broadcom VideoCore IV | |
| Minne: | 256 MB (delad med GPU:n) | 512 MB (shared with GPU) per 2012-10-15 |
| USB 2.0 portar: | 1x port | 2x port |
| Nätverk: | Inget | 10/100 Ethernet (8P8C) |
| Videoutgång: | Composite RCA, HDMI, LCD Paneler via DSI | |
| Ljudutgång: | 3,5 mm jack, HDMI | |
| Lagring: | SD / MMC / SDIO card slot | |
| I/O: | 8 × GPIO, UART, I²C bus, SPI bus med två "chip selects", I²S | |
| Effekt: | 300 mA (1,5 W) | 700 mA (3,5 W) |
| Elmatning: | 5 volt via MicroUSB eller GPIO header | |
| Mått: | 85,60 × 53,98 mm | |
Model A har 1x USB port direkt från BCM2835 chippet. Medan Model B har en inbyggd Ethernet adapter för USB som är kopplad till en intern 3x ports USB hubb som är ansluten till BCM2835.
