Something i'm really missing is the possebillity to insert a calibrated external voltage reference. Very easy to add i think!

Where you think that having it, will significantly improve the readings?
Where minivollts are readout from analog ports, The internal reference is stable, but still has about a +/- 10% error. To improve accuracy of the analog readings i mostly use little calibrated voltage reference modules. They have almost the same size as the transmitter module.
