BEFORE STARTING THE KIT...

  

 

Before starting this kit, prepare the following tools: 

● Soldering iron 

● Multi-meter 

● Flush cutters 

● Smaller pliers 

● n2. hex screwdriver or allen key (enclosed with kit) 

● Phillips screwdriver 

● Wrench No. 8 

● Protective eyewear 

● Isopropyl a smaller and clean brush (optional) 

 

We suggest that you work in a clean and a well lit and ventilated environment to avoid accidents or

 

 

 

 

     

 

   

   

 

 

   

 

   

losing any of the small components. Also briefly go through this guide and make sure that you

 

   

 

 

 

 

   

 

 

 

 

 

 

 

 

understand all the steps before you start soldering.  

 

When you are done with soldering, you would probably like to calibrate your Popcorn. It is pretty

 

 

 

 

 

 

 

 

 

   

 

 

     

 

simple. Please check the info about firmware v1.1 and calibration guide

BOTTOM BOARD 

 

RESISTORS 

 

Start with the bottom board parts. First of all, take your time and check the

values

of all

resistors

 

 

 

 

 

 

   

 

 

 

 

 

 

 

     

 

using a multimeter

 (or you can check the color codes if you are seasoned enough):

Then solder them on the bottom PCB and snip the leads close to the PCB (be sure to make this step

 

 

   

 

 

 

 

 

 

 

   

 

 

 

   

 

 

 

on all remaining leads in the course of this guide).
