Arduino Shield r3B4

  • Marking on bottom silkscreen for all red LEDs (LED_SP, LED_PROG1, LED_PROG2, LED_CC1, LED_CC2) is wrong (cathode and anode are swapped on HSMH-C170)
  • X18 has to be right angled since it is positioned too close to the CH1 heatsink

AUX PS r5B9

  • Side 2 of USB isolator (IC19) has no power connected. Add wiring from X10-1 to pin 16 and X10-4 to pin 9 if you'd like to add USB isolation.

Power module r5B9

  • Voltage programming switch (IC13) is not wired correctly. Therefore remote programming cannot be selected without simple PCB correction (see rprog_correction.jpg in Building instructions folder).
  • The main (Q4) heatisink is earthed, cut that PCB trace to decrease EMI (see heatsink_earth.jpg in Building instructions folder).
