8 pin connector with 5 mm pitch to 0.1 in plus prototyping area and two rails.

This not-quite-a-shield provides a barrel jack for the YUN, with a 5V LDO regulator and raises the board enough to put normal shields on without an issue.

Also included are two JST connectors and a prototyping area. One of the JST connectors is wired to the 5V input of the LDO and the other to the 5V output of the LDO. The prototyping pads are an experiment. A ground line and a power line run down the middle. The power line comes from the Yun’s 3.3V or 5V line and is selectable by jumpering the right angle connector to one side or the other.

NOTE: The silkscreen for this is not very good and may be refined in a subsequent version, if I feel like it.

NOTE: The slots for the barrel jack didn’t upload correctly. I routed mine out with a small drill bit, but I will probably fix this later with better features.

This is a small board with a lot of digits. Featuring four HP 4-digit 7-segment bubble displays on a board designed to be mated with the Adafruit HT16K33 breakout, this will quickly allow you to display four values using i²c. Source Files can be found on GitHub.

Note, the board to board connector on this version does not support normal header strip (the holes are too small) either use wire or appropriately sized machine pin connectors such as these.

Mounting:

• Solder a right angle header strip to the bottom header for vertical mounting.
• Solder straight header strips to the bottom or both headers for horizontal mounting.
• The top header is not electrically connected and is for more stable horizontal mounting.

This is a breakout of the ADAU1442/5/6.

The board breaks out:

• Digital Audio IO
• I2C/SPI
• All 12 GPIO pins
• CLKOUT
• RESET

It implements these circuits on board:

• Header for selecting CLKMODE, I2C ADD, PLL Mode
• PLL Filter
• 1.8V Regulator
• Crystal Circuit

v0.3 Changes

• Complete Re-factor
• Lengthened leads for easier hand soldering
• Slimmer to actually fit on breadboard
• Addressing can be done with jumpers or DIP switch
• Implemented the thermal pad

A breakout for the TMP102 from Texas Instruments small enough to fit inside a ¼ inch copper tube. This was inspired by the SparkFun breakout board for the same chip.

This is designed to be used with ¼ inch copper tube and thermal putty to create a water-sealed temperature probe. Instead of using a header to hookup, magnet wire is threaded through the holes and soldered. Using a solderable magnet wire is recommended. Alternatively, you could use conductive thread, but you should be careful to ensure that none of the wires cross.

NOTE: OSH Park shows the solder mask on the board image. The copper for the address connections is not connected, but the solder mask around them is removed to make addressing easier.

Source Files are a KiCAD project.
