Funkey Zero

We got a design bug on the LCD PWM MOSFET: the LEDA signal was driven by the N-MOSFET source instead of sinking by tits drain. We had to cut 2 traces and the problem was fixed, the backlight started to work.

But there is another problem with the LCD RESET signal, looks like it is not always pulled to VCC as it should. We may have to unsheathe the scope to debug.

But at least, the LCD is working, as you can see!

Thanks to AllPCB, we received the 5 (actually 6) PCBs in less than 1 week!

They look beautiful, the slot for the screen flat cable and the hole for the speaker are non-plated as requested, the oblong slots for the microUSB connector are just perfect too.

Now is time for some serious soldering work!
