Description:

Got a TV with no HDMI input, but still want to hack your Raspberry Pi? Don't worry! The Raspberry Pi comes equipped with a neat 4-Way Composite Video/Audio Jack, and we've got just the cable for you!

Plug this cable into your Raspberry Pi's composite 3.5mm Jack, and your Pi will output Video (1-line) and Audio (2-lines) via the three RCA connectors.

Specification:

Connector Layout

• Red - Video
• Yellow -  Right Audio
• Black - Left Audio

Features:

• Tested for Compatibility with the Raspberry Pi
• Gold Plated Connectors
• 3m Long
• Colour: Black
• Connector Type A: 4-Way 3.5mm Audio Jack
• Connector Type B: 3 x RCA Connectors

Contents:

• 1 x Composite Cable - 3.5mm to 3 x RCA

Resources:

Helpful Tips

• On first startup (when installing an OS via the NOOBs distribution), hold 3 at boot for PAL, or 4 at boot for NTSC. This will force output via composite insted of HDMI .
• If you have installed an operating system with an HDMI cable, and want to change to composite hold SHIFT 3 at boot for PAL, or SHIFT 4 at boot for NTSC

Notes on RPi4
By default the composite output on the Pi 4 is disabled because it slows the system down. You need to add this to config.txt
enable_tvout=1

What's in the box:

1 x A/V Composite Cable

Description:

The expansion board is directly connected on top of the Raspberry Pi using the board GPIO header pins, and no wiring nor soldering is required, and duplicated the 40-pin header of the R-Pi in order to support existing expansion boards. X200 is fully compatible with Raspberry Pi Model B and Pi2 model B.

The company emphasizes that their HDMI to VGA converter is not powered by the R-Pi HDMI port, as this is known to cause issues. You can find more information, including instructions to build the RTC drivers and control the servo with WiringPi, on the company’s Raspberry Pi page.

Features:

Input Voltage – 6V to 21Vdc converted to 5V, 3A via step-down DC/DC converter to power the Raspberry Pi.
VGA output – HDMI to VGA converter supporting up to UXGA (1600×1200) and 1080p with 10-bit DAC
Audio – 3.5mm MIC in jack, 3.5mm stereo audio jack, SPDIF output, audio IO connector (Microphone input and stereo audio amplifier 3.3Wx2)
Wireless - WiFi (IEEE 802.11b/g/n) with antenna, IR sensor (38KHz)
USB – self-powered USB hub with 3 ports
RTC – Based on DS3231SN with included CR2032 battery
Servo support – 8-channel Darlington driver chip  (ULN2803) allowing to control electronic circuits which require more current.
I/Os – Power output connector, headers to access camera connector on top of the Raspberry Pi
Misc – DIP switch to remove connection from RPi’s pin header
Dimensions – 85 x 56mm (Same size as Raspberry Pi)

Description:

This 4 channel Infrared Obstacle Avoidance Proximity Sensors Module supports 4 IR transmitter and IR receiver pairs that sends out IR energy to look for obtracles ahead.

Specifications:
 

• Working voltage: DC 3.3V-5V
• Working current: try to use more than 1A power supply
• Working temperature: -10 °C - 50 °C
• Mounting: M3 screw
• Detection distance: 1mm to 60 CM is adjustable, the closer the distance is, the more stable the performance is, and the white reflection distance is the furthest.
• Size: Central control board 4.4mm × 4.0mm × 12mm, small board 25mm × 12mm × 12mm
• Output interface: 6-wire interface (1234 is 4 signal output, is positive power, - is negative power(ground)
• Output signal: TTL level (can be directly connected to the I/O number of the single-chip microcomputer. When the infrared light reflected from the sensor is sensed, the red indicator light is on and the output level is low; when there is no infrared light, the indicator light is off and the output is level is high.)

 
Application:
 

1. Smart car or robot hunt (including black and white lines), along the black line path, also known as tracing.
2. The smart car avoids the cliff and prevents falling.
3. Smart car avoids obstacles
