PCB-cost of developement

Novice

Hello! I would like to ask what is the approx. cost of development of PCB with BOM for a, for example, GE864 GPS Telit module. It is a pretty straightforward job considering that all the specifications are given by Telit. And what is apprex. lead time for that? Thank you in advance!

    Hi,

     

    There are a lot of variables to consider but if you consider a basic set up as follows:

     

    1. Power Supply System

    2. LCD display (2x16)

    3. 8 Bit Micro

    4. Telit Modem

    5. RS232 interface or USB interface

    6. Misc Components

    7. Antenna

     

    Typically on low volume boards you could build the hardware for approx £200/board assembled

     

    Variables are complexity of external interfaces, size of LCD screen, power supply, volume of production etc

     

    Volume is key as this drives the decision to go to automated manufacture

     

    Lead time depends on your system specification

     

    Are you in need of a basic motherboard for the Telit modem instead of a system?

     

    Feel free to ping me some more details if you would like

     

    Cheers

      Thank you for the answer Stuart. We are in need of a basic motherboard design for the Telit module with the minimum number of elements for the module to be functional (power supply, antenna..). No need for LCD or anything like that. Basically we need a gerber file and a BOM. We would make production and assembly in China.

        Hi Johnny,

         

        This will reduce the cost significantly. approx 25%-30% of the BOM i would say. The Modem forms a significant part of the BOM cost.

         

        So you are looking at a board with modem power supply (design would vary depending on input voltage), antenna and you may need some serial port interface level shifting depending on the voltage levels of your controlling system. You will need an IO as a method of turning the modem on (or you could make it so that it is on as soon as power is applied), an optional IO line from the control system to the modem reset line and you may want to have the network LED connected or you may be happy with just "asking" the modem via AT commands.

         

        A SIM card holder my be needed if you are not using a Telit modem with on board SIM card holder.

         

        Which one are you planning to use?

         

        Other things to consider that impact design:

         

        1. Certifications needed: FCC/CE/GCF/PTCRB

        2. Use scenario e.g. body worn and/or fixed

         

        Regards

    The costs for the BOM are from free of charge up to Euro 15.000. For Euro 250 you get a design ready to copy with:
    - GL865
    - Two types of power supplies

    - Embedded GSM antenna
    - SIM holder

    - Small micro controller that runs as watchdog

    - Main code will run on Python

    A Python binary file is included as well.

     

    A customised PCB starts at Euro 4000 and normally end at Euro 15.000. Such a design contains then some I/Os as well. Writing the source code is than a part of the customer. Nevertheless writing of code for PCB and server can be offered as well.  More details we can discuss by email to harald.naumann (at) gsm-modem.de
