During the build of my own meat curing chamber I decided to develop a Mycodo breakout board for the Raspberry Pi 3 Model B+

I'm not planning on further developing this or selling it so i decided to make the files publically available for those who are interested of making one themselves.

DISCLAIMER

The use of any of the files regarding the My-Pi Breakout Board as well as the My-Pi Breakout Board it self are at your own risk!

The board is evolved from a hobby project with no commercial intents what so ever. No warranty or support is available and no commercial version will become available either.

The term "Breakout" means that this Board is intended to simplify connections to the Raspberry-Pi 3 Model B+ only, no forms of protection, short circuit prevention etc. are included on this board.

Features
The breakout board has connections for the following:

2x AM2302 sensor (DHT22 on a PCB with internal pullup resistor)
2x 12V 4-wire PWM PC Fan (1K pullup resistor for the RPM signal on the breakout board)
1x I2C LCD (or other I2C devices)
1x relay board (max. 8-way)

It uses a standard Aliexpress level shifter for shifting PWM and I2C signal levels from 3,3V to 5V

Furthermore it has a connection for a 5V/12V DC PSU which provides the fans, the relay board and the Raspberry Pi with power (open end micro USB cable needed for powering the R-Pi).

When using the same relay board I used it is possible to plug the breakout board directly onto the relay board with a 10 way female header. For other relay boards a screw terminal can be used.

That's great! Thanks for this. I haven't reviewed all the material yet, but it's very thorough. I'll attach an archive of the files to your main post as a backup to the dropbox link.
