You can choose to use a precision IC-mount or solder the MCP23017 directly to the PCB. We prefer an IC-mount so if you need to change the IC in the future it’s an easy job, choose is yours ;) If you choose to use an IC-mount note that it has polarity! The MCP23017 has polarity as well, the dot on the main PCB notes for pin 1, the must be corresponding with the dot on the MCP23017.

Next up is the 1N4001 diode, **WARNING** the diode also has polarity. Align the line on the 1N4001 with the line on the PCB.

When placed correctly it should look like this: Next up is the 1N4001 diode, **WARNING** the diode also has polarity. Align the line on the 1N4001 with the line on the PCB.

We recommended to use 2x8 2,54 male headers instead of 2 1x8 2,54 male headers on both sides of the Wemos S3 mini. This makes soldering the Wemos S3 Mini on the main PCB much easier.

Now it’s time to solder the 2x4 2,54 female headers like the picture above. Now it’s time to solder the 2x4 2,54 female headers like the picture above. Also the 1x3 2,54 male headers can be placed, above the MCP2307 see picture below. The jumpers had to be placed in the down position, as close to the MCP23017

If you had chosen to use an IC-mount it’s time to place the MCP23017 remember that the MCP23017 has polarity, the dot on the main PCB must be corresponding to the dot on the MCP23017 If you had chosen to use an IC-mount it’s time to place the MCP23017 remember that the MCP23017 has polarity, the dot on the main PCB must be corresponding to the dot on the MCP23017

Solder the USB-C port, do not bend any of the pins. The USB-C port from the kit fits only with the correct polarity. Solder the USB-C port, do not bend any of the pins. The USB-C port from the kit fits only with the correct polarity.

First, disassemble the displays and place all the 10mm female - female standoffs at the front of the main PCB with the 6mm screws. Keep in mind that at te corners at the back you have to use the 8mm female - male standoffs, this also applies to the middle 2 at the top of the back. At the bottom of the middle 2 you also have to use the 8mm female - male standoffs but these ones need a nut. Place on each 10mm standoff on the top of the standoffs an 1mm washer, place the displays on the top of them and mount them with the 6mm screws. But keep in mind that at the corners on the top of the fist (left corner) and last (right corner) display you don't use a screw yet, this is where the screw come to mount the front pcb in combination with acrylic front. Don't mount the front yet, we first have to mount the acrylic back with 8 6mm screws, after that it's time to mount the frond PCB in combination with acrylic front with the 4 8mm screws. Note that at the under corners you have to use an extra 1mm washer. First, disassemble the displays and place all the 10mm female - female standoffs at the front of the main PCB with the 6mm screws.
