Hello,
Im new in autoquad world but I decided to try it.
I bought M4 but forgot N4 exp board.
Installed on frame, desoldered EXP pads and soldered wires directly to pads #J2.7, J2.6, J2.10, J1.10 and wired signal wire from ESC (emax nano 12A flashed with BLHeli) to them and GND wire from ESC's to VUSB GND.
I also wired 5V from PDB to M4 VUSB. ESC's wired to PDB too. They was working fine with another flight controller.

Quad and wires looks a bit ugly but I will buy N4 and fix them.

After installing M4 I flashed It with latest firmware with ext_esc. Now I have some issues:
1. Flight mode not changed via 3pos switch (5.png - https://www.dropbox.com/s/1zex5auhxg25na1/5.png?dl=0)
2. Can't ARM (4.png - https://www.dropbox.com/s/ceomxnzhp5tazjj/4.png?dl=0)
3. Seems ESC's not initializing properly. When I used them with another FC after power ON I heared 2 grouped beeps - first one after power ON and second few beeps after few second. Ther first and the second rings are different. Now when I powering them I hear start beeps and after few second same beeps.
