Dear ,

Last year I bought that SunControl board via KickStarter .
Last week I use this with my birdhouse solar /camera project , using Raspberry Pi zero with additional camera .
I use a LiPo 3,7 V 6000mA battery with a solar panel 6V 2A.
First week everything works fine til now ...
Led "Done" light not anymore , only "power Good" and "Charge" led light on .Also the cip above "Curren Set" indication heathing up extremely hight , can't hold my finger on it .
In the picture and don't use my solarpanel but only try to charge my battery with a mobile adapter 5V 2A,Same problem ...

Can you give my further help with this issue, please?
Thanks !
Best regards,
Koen

Static? USB power spike? Solar Power Spike? Hard to say. It sounds like you have to replace the board. BP

Hi,
I also think that this charger chip is broken.
But, Can I get some details of this chip? I have smd-solder experience and can possibly replace it myself. And/or where can I order this chip?

Thx for the help and quick response , in meantime I ordered a new board from yours side , now "Sun Air Plus" , to do some experiments with.

Best regards,
Koen

If you have the skills, you can replace the chip! It is in the spec: www.switchdoc.com/wp-content/uploads/2017/07/SunControl_070517-V1.2.pdf BP
