Consider replacing DAC8568C with DAC8568A

5

The C grade have 5V full scale output, but due to VCC at 3.3V we only use half range at 2.5V and loose 1 bit of accuracy. We could replace...

Use correct capacitor value for loading capacitance of crystal. 33pf 50V NP0 is a good value.

Multiple levels of improving current design: - add protection diode to prevent negative voltage on transistor base - add LM311 to add proper protection and hysteresis

Move Recom far enough to allow placing a shrouded header. Also move the silkscreen labels.
