Hi Sonia,
No offence, but the schematics was not really the same
Do you remember the resistor which is a 100 Ohm and did you?
It should not be 100 Ohm
And do you remember the 78Lxx - it should not be this it is KF33BD - very nice 3.3 voltage regulators.
Also regarding the HEX, it was said it is not ok, cos of the EEPROM missing.
Best regards
Daniel
