 |{{ :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.
