style connectors for basepins 8, 16, and 24 for use with several Parallax Eval Board Accessories
- A USB-C connector for extra power
- A Propeller Platform style header for I/O
pins P32..P57 and also GND, 3.3 VDC, 5.0 VDC, and VIN

example code for the P2 Platform
- Notes on
Overclocking (running over 300 MHz)
- There is a solder bridge jumper close to the
reset button that (when closed) increases Vdd from 1.8 V to 2.0 V,
allowing the P2 to easily achieve 350 MHz or more.
