we are looking for expert guy from china, he will design a printed circuit board (PCB) to do work like usb hub with external power. in the market there are alot of this type of device but we need some special requirements: General Requirements: 1. the pcb will be connected to a battery 5000mAh 2. the pcb will be connected to mobile using usb type c 3. the pcb will be connected to Flash Disk. 4. the charger will charge the battery and the mobile on the same time. 5. the battery will charge the mobile with predefined conditions ( Always, below 40% of mobile battery ) this feature require software to mange this. 6. the pcb contains LED lights for indicator to give status of the external battery ( low, charging, full) 7. important: the flash disk must work and we can read its content on the same time while the mobile is charging ( charging by the external battery or by the charger). 8. On/Off switch to disconned the usb connected devices, but keep the charging and battery connected and work. Design Specs: 1. the PCB will be connected to a mobile using type C usb, and this cable must be FFC cable. 2. the connection between the FFC cable and the PCB must be using connectors ( no soldering). 3. the flash disk, or any usb device will be connected using molex connection ( data + power) the freelancer must have the ability to contact Chinese factories to bring the cables, connectors, batteries, and manufacture 3 samples of the PCB. any question you can ask in messages Regards,

Hello, I have read your project description and would like to offer our servuces for your PCB designing. Also we have manufacturing partners in China to help with samples and even later production. We have experienced engineers and programmers to work on your PCB and make sure best quality. We have been providing services to design and manufacture PCBs, BGAs and MCMs. We are specialized in layout for almost every SMT part that has leads on the edge (QFP, TSSOP, QFN, etc...) and have worked on hundreds of projects related to escape routing, blind vias, vias in pad, SMD pads vs NSMD pads, filled and open vias. You can check our reviews and contact me to see more samples. Thanks!
