1st Power up

Hello everyboedy. All my soldering is finished. Then i powered up like it is in manual with a mobile USB charger 2A. It didnt power up only all the lights flashed once and nothing else. Is there anything i can check ? I double checked the soldering pins and i can not find any problems. i also tried another charger with more then 2A same like with the other on flash after a couple of seconds and nothing. (Display black and all leds off)
best regards

can you send me photos, this looks like a undervoltage

try using 5v instead

and make sure that you also check that you didnt accidently soldered or burnt the cable

and make sure its power-delivery(pd) as well,

It is 5V powersupply

can i measure somewhere voltage to check, or can i check something else with multimeter?

try a different cable, and we will go from there


Hey @Karlgott,

You’ll need to fix some of the soldering joints for your Jay-D to work properly.
I’m adding photos of the soldering joints that need to be fixed here.

If you need any further help with this, please contact us directly at contact@circuitmess.com.

Best,
Monika
