HI, although I have no experience in electronic weighing scale unit design, but I have many years experience in electronic design and pcb assembly, my quotation is 750usd each, and the basic components selection should depend on your requirements, like accuracy class, minimum devision, budget, etc. In China, many design are base on hx711, and I prefer to choose STM32 and w5500 to complete this project. By the way, the price of small volume depends on the design and requirements as well. Looking forward to your reply, Thanks!!

Hi/Shalom, I have 16 years experience in embedded systems design and development and would love to work on this digital scale project. I will design and then make prototypes to test and then will send you tested project files in this bid. Sending prototypes will not be possible but I will help you to get parts to assemble and program the micro controller at your end. This bid is for both the scales. Please contact me to discuss what type of network connection you need to send the data through. regards, Ali LuSystems
