Kitprog 2 VOLTAGE UPGRADE

Important notice to users using our module with the KitProg2. There’s a mandatory voltage upgrade necessary as SWD voltages are out of specification.

It seems the voltage on SWD IO and SWD CLK will be set by measuring Vtarg. If Vtarg = 4.8V, the programmer will set the SWD lines to 4.8V which is too high.

Upgrade:

  1. Remove Schottky diode D1
  2. Place 2 1N4001 as shown
