Review schematic

Former Member over 13 years ago

Hi ,

I've designed a schematic for a uni project which involves the following main components:

Triaxial Accelerometer
Atmega328 Microcontroller
RN-41 Bluetooth Module (from Roving Networks)
Low Drop-out Voltage Regulator
Various other (i.e. switches, LED, capacitors, resistors, jumpers...)

This is my first time designing anything of the sort and it would be helpful if someone could review my schematic.

I am not sure if you are the right person to ask; but if not, do you know where I could look for such assistance?

I am planning on getting it sent to a manufacturer for a PCB to be made.

Best Regards,

William Kang

I have attached my (rather poorly designed) schematic as a PDF file.

Have you prototyped the circuit yet? You need to connect everything together and test it out to make sure you have everything laid out correctly.

Have you laid out the PCB yet? Typically a PCB manufacture needs a file of the PCB layout to start production. Unless you found one that will do the PCB layout for you. I've never come across one with that kind of a service. If one did offer it, it wouldn't be cheap considering the time and expertise it takes to plan a PCB layout.

Your schematic looks well laid out. But not knowing what the circuit is suppose to do its hard to tell if everything is laid out correctly.

Thanks for your reply! =]

Basically I want to send the data from the triaxial accelerometer via bluetooth to a pc (which has a bluetooth receiver). I've laid out my pcb design, but the airwires are soooo badly intertwined and overlapping; its going to take a while to get it all nicely wired.

The main help I need is verification of my schematic as this will affect my board (obviously lol) and the earlier I get my schematic done; the earlier I can work on my PCB.

A major factor in my design is to get it as small a form factor as possible.

Regards,

William
