Important notice to users using our module with the KitProg2. There’s a mandatory voltage upgrade necessary as SWD voltages are out of range with the default KitProg2.
With this modification, Vtarg of the KitProg2 is set to 3V3
- Remove Schottky diode D1
- Place 3V3 voltage regulator (L4931CZ33-AP in the example)
Vbus - Regulator input
GND - Regulator GND
Vtarg - Regulator output
- Add 2.2uF capacitor to GND <> Vtarg
