 Mine for example has a 10 kΩ pull-up (to 3.3 V) resistor on USB D+/PA12 instead if a 4.7kΩ (to 5 V), although USB devices use a 1.5 kΩ resistor to pull up (to 3.3 V) usually. Mine for example has a 10 kΩ pull-up (to 3.3 V) resistor on USB D+/PA12 instead if a 4.7kΩ (to 5 V), although USB devices use a 1.5 kΩ resistor to pull up (to 3.3 V) usually.
