ppBridge PCB top


  • Propeller Platform header patterns
  • Propeller Platform mounting holes
  • one RCA connector pattern
  • one stereo 1/8″ jack
  • one DIP8/SOIC8/TDFN8 pattern
  • four EXP connectors used by all Mikronauts modules and Parallax Proto boards
  • one I2C expansion connector – used by Mikronauts I2C modules
  • one H-COMM connector used by Mikronauts SerPlug, 485Plug, and Parallax Propeller Plug
  • advanced double-density bussed prototype area
  • silk screened labels for EXPx, H-COMM, I2C and PP headers

The RCA jack can be used for TV or audio output – use just three resistors and a jumper wire to implement a Propeller NTSC/PAL output, or experiment with alternate TV output circuits.

The 1/8″ stereo jack can be used for audio+video or stereo audio output, using either standard Propeller audio circuit or any other audio DAC.

The DIP8/SOIC8/TDFN8 pattern can be used to add another EEPROM, FLASH, FRAM device.
Of course, ppBridge  can also be used in reverse – to make Propeller Platform modules available to Mikronaut system users :-)

ppBridge application demo

For this demonstration, I stacked three ppBridge’s on top of my Propeller Platform.

The bottom most ppBridge had the TV and audio outputs populated, and was plugged into the Propeller Platform using simple male headers; I then used MIK-HF110S stacking headers to stack two more ppBridges on top. I added a MIK-BB-170 breadboard on the topmost ppBridge for easy experimentation :-)
