If you have the WiFi module, you need to install the SMD components on the board. If you are
using the WiFi module, don’t install header SV3, otherwise it becomes very hard to install the
resistors R40 and R41.
Notes:
•
Don’t install SV3 – you don’t need it
•
If you are not used to mounting SMD components, please take the time to read or watch
how to do this. It is not hard, but it takes a knack and some special tools.
•
Use thin solder (<= 0.6mm) for the SMD components
•
“Wet” one pad of each SMD component. For the resistors and capacitors wet the pad
where it will be easiest to “slide” the component into place. For the transistors and the
regulator, wet the middle pad
•
Use thin tweezers to place the components
•
The ESP 8266 must be mounted so that the body of the board sits over the K155ID1,
NOT
pointing outwards
Warning!
The ESP 8266 must point inwards to the board. It must not point
outwards over the edge of the board.
If you mount the ESP 8266 incorrectly, you will destroy it! The ESP 8266 does
not have any key to make sure it cannot be mounted incorrectly, so you have to
take care.
