Schematics are adjusted with Harware modifications, however there are still two hardware errors which are not fixed: The red/green led does not fit the connections in the footprint and does not work :( The pinout of U1 is wrong, ref and cathode? are exchanged The collpits oscilator is very sensitive to Battery voltage, a regulator is needed Layout and BOM are not consistent with schematics, need to follow schematics
