Kitprog 2 VOLTAGE modification

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


  1. Remove Schottky diode D1

  1. Place 3V3 voltage regulator (L4931CZ33-AP in the example)
    Vbus - Regulator input
    GND - Regulator GND
    Vtarg - Regulator output
  2. Add 2.2uF capacitor to GND <> Vtarg
