|{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 25.jpeg?direct&200 |As (for now) last electronic component, solder the 28-pin LPC1114 socket in. One end has a groove, which should point to the right.}}|{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 26.jpeg?direct&200 |There are 6 Molex KK256 2-pin headers for various purposes. Direction isn't crucial, but it's a nice idea to stick to the layout.}}|{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 27.jpeg?direct&200 |Stepper motor headers are Molex KK256 4-pin. Don't save too much on solder, as quite some current flows through these pins.}}| | |{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 25.jpeg?direct&200 |As (for now) last electronic component, solder the 28-pin LPC1114 socket in.

|{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 28.jpeg?direct&200 |To complete with the KK256 parts, add in the 6-pin SPI headers. Here it's an even better idea to stick to the layout, as plug-ins for this header may also rely on this convention.}}|{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 29.jpeg?direct&200 |Now the somewhat bulky USB header. It snaps into place. Make sure to also solder the snappers, as these are needed for proper shielding.}}|{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 30.jpeg?direct&200 |When inserting the disk power header, it's crucial to get the chamfers right (to the outside). Else you'll have only 5\_volts to drive your steppers.}}| | |{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 28.jpeg?direct&200 |To complete with the KK256 parts, add in the 6-pin SPI headers.

|{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 31.jpeg?direct&200 |The 8-pin ATX12V header has a nose, which must point to outside of the board. Don't save on solder, big currents are going to flow here.}}|{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 32.jpeg?direct&200 |The ATX24 header has also a nose, this time it has to point inwards.}}|{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 33.jpeg?direct&200 |This is the header for the extruder heater. Similar to the KK265 2-pin, but bigger.}}| | |{{ :Gen7:Gen7 2.0:Gen7 2.0 Assembly 31.jpeg?direct&200 |The 8-pin ATX12V header has a nose, which must point to outside of the board.

| Tadaa! You're done with soldering. Well, almost :-) |
| |
| Now you can continue with [[Gen7 Board-ARM 2.0#Voltage Measurements|Voltage Measurements]], it's a good idea to insert sensible parts only after that. |
