I am releasing a spin on the Little Bang Board.  Changes and Improvements are:

• Buttons are activated by pulling to GND
• Added option for either LIS3DH or MMA485X accelerometer
• Added interrupt line for accelerometer
• ADS1115 module option for increased ball plunger accuracy. Regular Pico ADC is still supported.
• JST connectors have been replaced with two each, 2.54mm pitch 10 contact terminal blocks.

Here is an image of the PCB:

 

 

New version retains expansion port for an output board (I'm still working on this) and is still Pinscape Pico compliant.  Special Thanks to MJR for the design review.   Comments, suggestions and recommendations are always welcomed.

 

Regards,

Folks,

 

I started thinking about what I should include on my Little Bang expansion board and I came up with a brilliant idea.  I could make a couple minor modifications to my expansion interface and it could accommodate MJR's Pinscape DIY Power Board.  This would give us 16 high power outputs and 32 Lamp outputs (1 amp each).  I still need to groom the PCB before posting the project on my GitHub page.  PCBs will not be available for a couple months.  Below is the new schematic.  

 

 

 

As always, questions and suggestions are always welcomed.
