Summary

This is the casing for the 5V RAIL D1M BLOCK. It allows the 5V pin to be connected to an external power source. The range of voltage that the Wemos D1 Mini (5V pin) can operate on (and the regulator handle) is ~3.0V to 5.5V.

I primarily designed this for battery operation where the battery is charged via solar cells and a TP4051. I can see this being useful where more current is needed on the 5V rail directly (like adding 4 off MQ-* sensors via an analog multiplexer at 100mA each).

These components, a PIN JIG for soldering, and 2 off 8 pin 10mm Long Needle Female Pin Header Strip are required for this build.

Post-Printing

Steps prior to gluing the lid

Follow the instructions up until "Step 5: Gluing the Lid to the Base". On step 4, adding a dob of hot glue prior to inserting/aligning the board with headers is advised.

Adding the screw terminal

Brush Strong Cyanoachrylate Adhesive onto the base of the screw terminal. Insert pins through holes in base with wire openings pointed down (away from lid). Carefully clamp and allow to dry.

Wiring the protoboard

Solder wires from the screw terminal pins to the GND and 5V pins. Mark the top of the screw terminal with red and black to show the polarity of each terminal.

Adding Lid and Labels

Follow the rest of the instructions from "Step 5: Gluing the Lid to the Base".
