Hi @Håkon Alseth , I have the same problem, my PCA10040 board has damaged today :( I tried to fix it suspect D2 and U3 element, but after replace it turned out to be MCU. I also desoldered MCU and the supply comes back to normal. I can buy new ATSAM3U2CA-AU and try solder to the PCB .

Can You tell me whether it is possible reload the firmware ?

Best regards

Mateusz Drewniak

Hi Håkon,

I just received a brand new shining n52DK board. Please accept my biggest THANK YOU!

Your solution is not only fast but extraordinarily efficient.

Hi Leo,

While I do admire your dedication, wouldn't it be easier if I sent you a replacement board?

If you send me a direct message with your name/address/phone number (requirement by DHL), I'll make sure a new kit is on it's way to you.

Best regards,

Håkon
