Pinscape Jr Sch 1

This is a schematic for a Pinscape Pico Jr. The design is based on MJR's Pinscape Pico Main Board DIY.   The design includes 16 PWM output channels that are terminated to a 34-pin IDC ribbon cable header.  Of course, there is support for an accelerometer, either LIS3DH or an MMA485.  Ball shooter or plunger interface is through a ADS1115 only.   This differs from MJR's reference, as he had made this optional, but because of lack of DIO I could not add this option.  In retrospect, I could have multipurposed GPIO 28 as both optional analog input or as the interrupt. Let me know if I should do this.  Last is MJR's board expansion port that allows the addition of his Power Board or other peripherals.
