This is the casing for the Wemos D1 Mini Dual Base. It allows 2 stacks of D1M BLOCKS in your layout. This provides a labelled module that is stack-able, providing a ready-made shell for your IOT circuit designs.
These components, 2 off PIN JIG for soldering, and 4 off 8 pin 10mm Long Needle Female Pin Header Strip are required for this build.
Align large, non-beveled surface to bed.
Soldering the header
This Video gives a guide for soldering using the pin jig. It will be done with 2 sets (4 off) headers. The large numbers on the board (1, 2) will be on the male pine side of the header. The Instructable section "Step 2: Soldering the Header Pins (using the PIN JIG)" gives more details.
Fastening to the base
Place the shield with soldered headers into the base, headers first into the slots.The 3.3V side will be adjacent to the grooved external surface of the base. Fasten the 6 off 4G screws into the holes in the PCB.
Gluing the lid
The instructions in the section "Step 5: Gluing the Lid to the Base" show the procedure. Additional glue will be needed in the centre tabs on the lid.
Adding the labels
The bottom pinout labels really do not serve any purpose on the bases. Follow the instruction in "Step 6: Adding the Adhesive Labels" for adding the identifier label.
