Arduino-based Ethernet I/O PCB design and routing job

The job is to design and route a relay board with Ethernet connectivity. We will do the high-end programming. Attached is what it should ressemble in the end. Below are some example Arduino schematics to get inspired: - [login to view URL] -> for the ethernet part - [login to view URL] -> for the processor part - [login to view URL] -> for the relays part Basically the board I have in mind will be kind of a mix between an Arduino Mega, the Ethernet shield and the relay shield + some small additional things (RTC, opto-isolation of digital inputs...) Basic specs: - Atmega2560 16MHz uC (with access to ICSP interface to flash bootloader) - programmable with Arduino IDE - Ethernet 10M/100M RJ45 internet interface with connection and activity LED - 8 Relay output's 230VAC 10A or 30VDC 10A - Form-C relays, screw terminal and SMD Status-LED for each - 8 opto-isolated digital inputs (with SMD Status-LEDs) - 2 analog inputs 0/10VDC (10 bits) - 2 digital pulse counters (using the AT2560 timers?) - Pin header connected to remaining free pins of uC - RTC module (eg. DS1307, PCF8523, or DS3231) - SD card slot (eg. to serve a Web page reflecting the I/Os and setting parameters) - DIN rail format (eg. PCB Size 143mm x 72mm) Deliverables: - all schemas and project files in a standard format (Eagle, KiCad, etc) - all files + BOM necessary to have a prototype board manufactured
