I need an AVR and SIM900 based board designed.
The SIM900 will have buzzer, LED for network status, power, etc.
I am writing here Arduino Pins: ATMEGA328P with 16MHz crystal.
The pins 0 & 1 are Rx and Tx respectively. These pins go to the SIM900 Tx and Rx respectively.
The pins 2 & 3 will be opto coupled inputs just like the PIC PLC board you make.
The pins 4 will be out to a pin header, with VCC and GND.
(The pins 5,6,7,8, 10,11,12,13 goes to the ULN2803, the output of which goes to the 4 relays that are connected with 5,6,7,8.
The rest 4 pins of the ULN2803 will just go to the Pin headers. This might change a little as I need only 4 relays so, we I will take the SPI pins out).
The pin 9 will also go to a different pin header, like the pin 4 with its own VCC and GND.
The A0, A1, A2 and A3 will again go out to a 4 pin header, with 4 rows of Vcc and GND.
I would like a DS1307 RTC connected to the pins A4, A5 (SCL/SDA).
The board will also have LM2596 based power supply.
The relays would be the normal 12V sugar cube relays, with 4 relays 10AMPS
There should be ISP pin headers also.
Preferred 2 sided PCB with sufficient spacing between traces and large pads for easy soldering.
Let me know, if you are interested, lets start will designing the schematics and PCB layout.
I need the 3D model also.
Dear Hiring Manager,
I have gone through the job posting and find it's exactly matching with my technical capabilities and willing to work on it.
For last more than 10 years, I am working on product design in embedded and electronics area. I have exposure on circuit design, schematic & PCB design, BOM, components selection, Prototype assembly etc.
I have developed many single/double/multi layer PCB board designs using Altium Designer, OrCAD, Eagle etc. I have worked on simple to complex PCB designs as per requirements.
I will do design as per your requirement considering design standards IPC2221, IPC2222 and EMI/EMC design points etc.
I will provide you complete schematic and 2 layer PCB layout design.
Looking forward to hear from you.
Thanks with Kind Regards,
Ghanshyam

Hello,
I hope you are enjoying good health.I have done a similar project in which mobile phone was being used to control AC. You can check the details of this project in my portfolio. I have also experience of working on arduino uno. I can design the required PCB layout either in Proteous or in Altium Designer.
Thanks,
I understand that yours is a project for GPS industry. Your requirement for a layout and 3D model can be done in Altium Designer, check out my portfolio for previous projects completed.
Please contact me in case you need any further clarification.
Can help... I am an Expert... Lets Start!
Please start a Discussion with me and we can get started from there...
Please check the past projects I have handled and check my reviews for what employers have to say about my work... Can start right now...
Hello,
I made several PCB designs in the past.
I made I/O boards with PIC's from Microchip and also communication boards with ethernet and serial.
Expansion boards for PIC32.
I have also experience with the implementation of a design, so I made PCb boards and I understand your needs.
Trust me and choose me.
Best regards,
Boros Csaba
I use Protel for PCB layout, have done projects upto 8 layers so far. These are for boards that are used in our company.
What software will your schematic be in ?
If you want to move platform to Microchip or TI ( MSP430 ), we can assist you there too.
With regards
