Hello all,

I am doing a project where I have to design a PCB. I am new in this 
field. I am using EAGLE PCB software.



About my project: I am working on a project where I have to measure the 
environments temperature. I am using TI's CC2541 Bluetooth soc, temp 
sensor TMP102, DC DC convertor, SOC debug flash TSW-105-02-S-Q and 
MURATA's Balun transformer. Whenever I put the battery in my PCB, the 
temp sensor reads the data and send it to my phone via Bluetooth. For 
this PCB design I am using eagle software. Since I am new to this 
software and I am working alone in this project I want help from you 
all.



Till now I have the schematic design on software. I am attaching my pdf 
file here, so you guys check the file and tell me if I am going in a 
right direction or not?

And also how to check the design if it is correct or not? I clicked on 
the error button, it is showing warnings only not an error.

guys can you help me with this?

If you are new to the subject of circuit design, a RF design is hard to 
do. You should have a look at the TI reference design here:

http://www.ti.com/tool/cc2541sensortag-rd

They are using a 4 layer PCB. If you want a working board I would 
suggest to copy schematic and design and add your special requirements 
to design and board. You should not change the RF part of the layout.

I am using the same ti sensor board diagram....i haven't changed 
anything...I just copy that circuit and made to my requirement....just 
check my diagram once more...the rf part is the same as sensor tag....

Einhart doesn't refer to your schematic. He is talking about the pcb 
layout.

Best regards
Guido
