16-Bit Register Design - Rev 4.1
Includes 2:1 MUX, register, and bit test unit; all components optional.
PCB-GP is production-ready; it has teardrops and ground-plane. If not present, it means minor tweaks are ongoing.
Version 4.0 has numerous improvements, including fatter traces, better power input. Strongly suggest that 12v relays be used due to voltage drop issues with lower voltages.
