Assembly: 

1)

 

In order to assemble the module, you need the following tools: 

 

*It is recommended to have some isopropyl alcohol and a fine soldering brush handy to clean off 
the excess flux on the circuit board when the soldering is done.  

 

*ATTENTION* DO NOT USE RUBBING ALCOHOL, IT WILL DAMAGE THE COMPONENTS. 

2)

 

Open  the  package  and  verify  the  components.  (refer  to  section  4.  Bill  of 
Materials on page 3) 

3)

 

Lay down all the components on your workbench and proceed to the next step. 

4)

 

Prepare your soldering tools.  

a)

 

Use  an  appropriate  tip  for  the  application.  Also,  make  sure  the 
soldering tip is clean. Gently use a brass wool or a brush to clean the 
tip when needed. Another way of cleaning the soldering tip is to use a 
wet sponge.
