According to the solution architecture, we will promote our clients the smart device that goes with it. Most of time, we will promote the smart devices that could have been mass-produced in existing projects, because of the real-practice. For customizing the product build and design, we are able to the solution based on the existing PCB(Printed Circuit Board), and to develop the production die of new design. If the clients request to develop PCB design, or to enable the product with new sensors/ functions/logical unit of work, we will provide the full solution of PCB and hardware design. Except for that, we will product the manual sample, or the trial products of small batch with the full solution. After trial-producing, we will provide 20 to 100 pieces of sample devices to the client, and make sure the full solution could be applied for mass production economically and stably.
