RAK10702 WisBlock Indoor Comfort Node Assembly Guide

This guide shows you step by step how to assemble the electronic components and how to assemble them in the (optional) enclosure. This guide is for the version with the 4.2" E-Ink display. If you are using the version without the display, you can skip certain steps.

Assembly Guide

As the RAK10702 is a DIY product, this document will guide how to correctly assemble the electronic components and place them in the optional available 3D-printed enclosure.

Assemble the Front Sensor Component RAK13013

Plug the Wisblock RAK1901, RAK12010 and RAK12047 on the RAK13013 sensor carrier module. Fix the modules with 3 pcs M1.2*3 Screws.

NOTE

The following steps are only required if the kit includes the enclosure.

Assemble the Front Sensor Carrier and the Base Board on the Enclosure Lid

Fix the front sensor carrier PCB on the mounting plate with 3 pcs. of ST2.0*3 Self tapping screws. The FPC passes through the slot on the mounting plate.

Figure 10: Screw the front sensor carrier PCB

Fix the Base board and sensor on the mounting plate with 9 pcs. of ST2.2*4.5 self-tapping screws.

Figure 11: Screw the base board and the sensor

Insert the two FPCs from the PM sensor and the front sensor carrier in the sockets on the Base board. The operation of the connector is the same as Figure 12.

Figure 12: Insert the FPCs into the sockets of the base board

Bend the FPC of the display screen carefully, and insert it into the connector of the RAK14000. Then close the display screen into the slot of the mounting plate.

Figure 13: Bend the FPC

Place the top cover on the mounting plate. Flip both the mounting plate and the top cover over and fix them with 6 pcs of ST2.2*5 countersunk head self-tapping screws.
