Prototyping plate

The Adafruit prototyping "plate" (ie, daughtercard) is available here.

If you put a mini-breadboard in the middle it obscures the silkscreen markings for the port numbers so the above picture can help determine which header pin corresponds to which channel.

Hardware Interfaces

The Raspberry Pi has a 26-pin BERG stick style header which has the interfaces to connect up external hardware. They provide 8 GPIO pins plus access to I2C, SPI, UART), as well as +3.3 V, +5 V and GND supply lines.

WARNING: GPIO voltage levels are 3.3 V and are not 5 V tolerant. There is no over-voltage protection on the board.

Composite Video

4-Pole A/V Connector

The Raspberry Pi Models A+ and B+ have a 4-pole 3.5mm connector which has right/left audio and video
Cheap ebay connector didn't work because of pinout
- Cable has outer ring as ground
- Raspberry Pi has outer ring as video

Re-wired cable and it worked

3.5" Composite Output Monitor

Software Setup Composite Output

Using a Mini PAL/NTSC Display with a Raspberry Pi To configure Raspian for composite output Reboot the Raspberry Pi and enter your username and password. To edit the configuration file, enter the command sudo nano /boot/config.txt Add sdtv_mode=0 Normal NTSC Comment out in 2 places

hdmi_force_hotplug=1

Uncomment and add a/r framebuffer_width=320 framebuffer_height=240

Pi Mechanicals

The Raspberry Pi PCB measures 85mm x 56.2mm excluding overhanging connectors and is 20.8mm high. Pi Mechanicals are complicated due to a lack of adequate mounting holes. Various methods have been developed to deal with this deficiency. The primary method is clamping the card from the sides.

Setting a Static IP on the Raspberry Pi (Raspian Stretch)

This is for Raspian Stretch and newer (as of 2019-01) See here for configuring the IP address for older versions of Raspian (Jessie) To find out which version of Raspian is running cat /etc/os-release

From Configuring a Static IP for a Raspberry Pi running Raspbian - (Retrieved 2019-01-19). Open the config file for editing.

sudo nano /etc/dhcpcd.conf

At the bottom of the file add settings:

interface eth0 static ip_address=192.168.2.31/24 static routers=192.168.2.1 static domain_name_servers=192.168.2.1 8.8.8.8 4.2.2.1 static domain_search=example.com static domain_name=example.com

Setting a Static IP on the Raspberry Pi (Raspian Jessie and earlier)

This is for the older Raspian Jessie and earlier versions of Raspian See for setting the IP on Raspian Stretch To find out which version of Raspian is running cat /etc/os-release

Network Static IP Addresses

There are two networks. The .1 network connects to the router to the Internet. The .2 network connects to the PiRouter.

Main .1 Network Static IP Addresses
