Allo Houston, we have a problem !!
I just finished the JA pcb, and started the test phase.
- Installing Midibox NG : ok
- Loading seq_l : ok
- Set debug on : oktests: no answer ! no button works and no LED reacts. I started by checking if I didn't make a mistake with the cables and in the resistance network but , everything seems correct, no visible solder bridge either (or maybe i missed something). However, I noticed that the ICs get very hot during the test. Apart from that, I admit I don't know where to start verifications.
Here are the pictures of the pcb. Thank you in advance for your help:)(yes the pins near matrix are soldered upside down (ourgl), going to correct that with my hot air station ^^)

Merci @Antichambre !, did you use specific led with your mec ? i was about to choose standard 3mm 3.3v led rated for 5000mcd, is it enough bright for this kind of caps ? sorry for my my noob questions ;)
