✔  All components
[http://remoteqth.com/img/wiki-rotator-server-04.jpg]
❏ Solder J2 GPIO connector on bottom of pcb - {.redka#id color: #f23f37;}'''with the exception of pin 17'''{/}
[http://remoteqth.com/img/wiki-rotator-server-05.jpg]
❏ Next R1 R2, D2 D3 D4 D5 D6 D7 D8 D9 and C1 C3 C4 C5 C6 C11 C7 C8 C9 C10
[http://remoteqth.com/img/wiki-rotator-server-06.jpg]
❏ All pin strip and connector J16-19
[http://remoteqth.com/img/wiki-rotator-server-07.jpg]
❏ The remaining components - K1, U2 U3 U4 U5, CONN1 CONN2 CONN3 CONN4, F1, R3 R4 R5 R6 - '''before by soldering turn fully CCW, and put on control screw towards to diodes {.redka#id color: #f23f37;}= center of the potentiometer must be routed to ground,'''{/} J8 
[http://remoteqth.com/img/wiki-rotator-server-08.jpg]
❏ Last IOs U1 ULN1 ULN2 and two mandatory DC/DC converters for Raspberry PI and rotator modules - {.redka#id color: #f23f37;}before#f23f37;}'''before mounting must both be set to the output voltage of 5V, otherwise you risk damaging RPI and arduino{/}arduino'''{/}
