Hey all i am in need of making a clone of this board (See attachment) but with some modifications: - convert this USB to Ethernet using ENC28J60 module (already built). - ADD a 10-pin female socket in order for the ENC28J60 to use (it would be sitting upside-down on the board). - I only need 4 x 4-pin fan sockets. - I only need 4 x 2-pin temperature sensor sockets. - convert all items on the PCB to SMD so that the PCB can be as small as can be. - ADD a 1 x 3-pin header to control an WS2812B LED string. - ADD the PICs programming pins in order for me to flash the HEX file using the PicKit3. - EACH 4-pin fan will need to be individually controlled. It looks like in his schematic 2 parts of 4-pin fans use the same PWM speed? In place of the udn2981a feel free to use a newer IC since that is discontinued or you can use the ADT7470 IC or no IC at all if the newer PIC can do this already. - For the power, use a SATA power socket for 3.3v, 5v & 12vdc (see attachments) can be placed wherever on the board. See attachment for eagle schematic for that SATA connector. - PCB Gerber needs to be compatible with OSHPARK. - Feel free to update the PIC18f4550 chip to something more modern if needed. I have attached all files that should be needed for this project. I consider this project pretty easy as a LOT of stuff has been done for you aside from adding a few things. And dont worry about the windows program for this. As long as you give me serial data output/input then I can create the windows program myself.

Hi Sir, We were discussing, why you reposted the project. I have already completed the projects for clients in USA who manufactured the PCBs from OSHPARK. Please keep noted that very very few freelancers here who are aware of oshpark DRC rules. so i bet with you that the freelancer may be succeeded in making nice pcb for you but he may failed to comply with DRC checks required for OSHPARK. Now i am fresh biding. and i am very much looking forward to work for you. Looking forward to hear from you again. Regards, Ahmad Lead Technical Engineer Turktronics

Hiya, Nice project, wrong budget, mostly wrong selection of parts. Depending if this is a one-off or something you plan to manufacture in qty > 2, I would have different suggestions for the hardware. In either case, PIC is ancient and using ENC28J60 is dumb because pretty much any modern micro has ethernet MAC already built in. I'd suggest using something like STM32F105 (or 405, or anything with Ethernet), these chips have plenty of hardware timers (PWM), I2C bus ( for proper temperature sensors ), plenty of ADC channels (in case you insist on using analog LM335Z parts ), etc. If you're just doing a one-off there's some STM32-nucleo boards with ethernet on them already that you can make a shield/topboard with the sata power/fan/sensor sockets and that would probably be the most cost-effective solution for a one-off board (nucleos are around $20-30). I'm not really sure where you're getting "This is a pretty simple" project, when you're talking about taking some ancient stuff from nearly decade ago, using obsolete parts, switching it to ethernet control, swapping MCU to something completely different (because who the fuck uses PIC in 2017), no, it's not simple. The budget is also too low, even my bid is too low but freecancer doesn't allow bidding a lot over original budget, I'm going to guess this is around 2k worth of work including prototype and firmware development.

Hi I can design the board using SMD components to make it physically small and have all the necessary hardware features you want including the ethernet socket and ENC28J60 connected to a low power mcu, or we can keep the pic18f4550/2550 as it is a good choice too. Regards
