Today I completed the schematic.

The completed schematic and design is online at https://github.com/abhishek-kakkar/beaglelogic-standalone.

Apart from 16 logic inputs, BeagleLogic standalone shall also incorporate a 24-pin expansion header that breaks out:

• 1 UART
• 1 I2C
• 1 SPI
• 1 Quadrature Encoder input (2 pins)
• 2 PWM outputs
• 6 GPIOs
• CLK input to PRU1 is also broken out for experimental synchronous captures with BeagleLogic

Work on the layout will begin soon.

Here's a link to the PDF of the schematic.
