Instructions | Play ESP DIY Kit

1

Start by checking all parts are present

Make sure that all parts came in good shape and no apparent damage is done on the way. (If not flashed yet) flash Play-ESP software to the Wemos module just to make sure it works.
2

Solder Buzzer in place

Solder in the buzzer on the back side of the PCB. Note the polarity.
Cut buzzer legs when done.
3

Solder Wemos module - headers to module first

Solder headers to the Wemos module. Long part of the header should be directed to the motherboard. Make sure to align them right, use motherboard as an aligning tool. When soldered it will be tightly pressed against battery socket.
Start with just one pin each side and double check your work. Then you can proceed to other pins
4

Solder Wemos module - motherboard side

Solder headers to the motherboard from the back side. Do not use too much solder, just enough to make solid connection. Excessive solder will block battery connector later on.
5

Assemble screen

Assemble 4 brass rings on the screen. Use 4 M2 screws.
6

Screw screen to the motherboard

Use remaining 4 M2 screws to connect screen to the motherboard firmly. Make sure the screen is well aligned.
Double check screen alignment and solder screen in place. Do not leave large tin bulges.
7

Solder battery socket in place

Place battery socket between Wemos header pins, it should just barely fit. Double check alignment pin and corresponding hole in the motherboard. It will not lay perfectly on the back side of the motherboard because of the screen connector and bolts, but it should be solderable nevertheless.
