Project Description:
I need to make a Raspberry PI expansion board. I already have the base schematic, but i need someone to make it normalized, i need it to be professionally designed. On this board a will use: 1 x MCP23017, 1 x ULN2803, 1 x MCP3008. I need someone who already own a Raspberry PI for measurement etc. I want to make the majority of the output goes thru a strap cable to another little board with this connector on it: CPC 2-208224-1. I would like to have a place onboard to connect a gps receiver if need be. The scematic is pretty simple, But i need someone to put it to standard, i need circuit protection, stability etc. I want to power the PI from this expansion board with a 5v power supply. I need someone that know electronics and connector type, I am in Canada i we must use part that are easily avaible here. Thanx a lot!

Just to add that i will need 2 PCB, the main one based on the schematic attached and a little one to connect via flat cable connector to this big connector that is going out of the box.

I will feed the power to the PI from the expansion board, i will connect a 5v 2.0A external power supply, i want the circuit protection and component protection, the attached file is a really base schematic, it need to be worked out and with component and circuit protection. I would like someone that will be able to help me get a 1st protoype of this board manufactured, i would like it surface mount chip if possible and i would like to get some help to find the better place to get this manufactured. Thanx a lot!
