- Pi3B power budget
- up-to-1000mA (1A) for SoC/RAM
- 300mA for WiFi/BT
- 50mA for GPIO pins, distributed across all the pins
- individual GPIO pin can only safely draw 16mA
- 50mA for HDMI port
- 250mA for camera module
- 100~1000mA for keyboard/mouse
- 1200A for full powered USB
- A single ARM core, the ARM1176JZF-S, licensed from ARM Holdings
- A 1080p30-capable graphics processor, the VideoCore IV, developed and owned by Broadcom
- 128KB of Level 2 cache, shared with the CPU but used primarily by the VideoCore IV processor
- A suite of peripherals for the use of the ARM11 core, including:
- An interrupt controller
- Timers
- A pulse-width modulator (PWM)
- Two universal asynchronous receiver-transmitters (UARTs)
- A general-purpose I/O (GPIO) system providing 54 I/O lines
- An inter-IC sound (IIS or I2S) system and bus
- A serial peripheral interface (SPI) master/slave bus mechanism1

- Taking photos: raspistill is a command line application that allows you to capture images with your camera module. e.g.
raspistill -o image.jpg- reverse:
rapistill -vf -hf -o image.jpg
- reverse:
- Recording videos: raspivid is a command line application that allows you to capture video with your camera module. To capture a 10 second video with your Raspberry Pi camera module, run
raspivid -o video.h264 -t 10000>at the prompt, where "video" is the name of your video and "10000" is the number of milliseconds
