PKE Meter Electrical Components and Parts List

This guide is a list of all components and parts for the PKE Meter Kit. It can be used to source parts and identify individual pieces that you may need to complete your build. You can also view and print our packing list sheet for the PKE Meter to help keep track of the parts you have or need.

The PCBs used in this kit are created and sold by Pixel Props Store exclusively.

These are all of the various LEDs required:

  • 3mm Flat Top LEDs  14 white or yellow 3mm flat top LEDs – These are for the wing PCBs
  •    14 green round 3mm LEDs – These are for the pattern PCB
  • 1 Green Square LED 2mm x 5mm x 7mm – This is for the pattern indicator under the main screen area
  • 1 Yellow Square LED 2mm x 5mm x 7mm – This is for the pattern indicator under the main screen area
  • 3 Red Square LEDs 2mm x 5mm x 7mm – This is for the power light, and touch sensor indicators

For the servo movements, you need the following:

  • 1 MG90S servo with metal gears
  • 1 servo pushrod – 1.3mm
  •   1 servo pushrod connector – 1.3mm round head

For the Audio on the PKE, these are the parts you need:

  • Dfplayer Mini1 Dfplayer Mini MP3 Module
  • 1 SanDisk 16 GB Micro SD card, Class 10
  • 1 Audio Amp – 5v
  •   1 Speaker – 8 Ohm 2W 


These are individual components that are required:

  • 1 5v booster board – Type-C USB 5V 2A Boost Converter Step-Up Power Module Lithium Battery Charging Protection Board
  • 2 switches (one for the main screen and one for on/off) – SS23E04 8 Pins 3 files 2P3T DP3T Handle high 5mm
  • 1 piece of wire for the touch sensors 18 Gauge
  •  1 brass rod – 3mm x 100mm 
  • 1 Charging power jack – DC005 5.5×2.1mm 3 pin
  • 1 470uf 10v Capacitor
  • 2 1k Ohm resistors (1/4 watt)
  • 4 220 Ohm resistors (1/4 watt)
  • 1 Rectifier Diode 1N4001 1A 50V
  • 1 Green Acrylic screen with grid sticker
  • 1 WH148 Single-Joint Potentiometer – 10k Ohm
  • Bluetooth Module – HC-05 – The HC-05 isn’t compatible with iOS. Use an Android phone to connect to this module. Use an HM-10 instead. I have no way to test this as I don’t own an iPhone but this has been confirmed to work. Connects the same as a HC-05. 
  • 1 USB C Male PCB Adapter
  • 1 Arduino Nano
  • 1 set of Battery contacts for a 18650 battery – Positive Negative Conversion Spring Contact Nickeling Plate 12mm x 12mm
  • 1 row of 20 Header pins (90 degree) – This is only if you are going to attempt to use DuPont Connectors
  •   2 count 74HC595 Shift Registers
  • 1 USB charging cable
