Hi, I see you need some help with your project. I have experience in PCB design with KiCad and I have also worked previously on the implementation of the protocol. Modbus RTU in Arduino and STM32 Boards. I look forward to hearing from you soon. Thanks!

I can design the board as per your requirements, get it manufactured here in China(I work for an automotive startup here). Afterwards, I can test it and send you the tested board along with all the design files etc. Your budget for this project is very low, usually I charge more but I believe that creating new relationships is more important than one project. Contact me and we can discuss it further.

Hello Sir/Mam, I read your requirement, and this is very easy and suitable task for me. I m willing to handover your project in given deadline.

Hi i can help you to make the mode bus unit with schematic, PCB and firmware. I have 5+ years experience in PCB designing and firmware development involved MODBUS, MCU and isolated industrial automation system designing. Please let me know more details you wish to have such as expected BOMO cost, PCB size expected mounting (enclosure) methods to help you.

Dear Sir I introduce myself as vijay from INDIA , I am an experienced embedded Design engineer and have implemented lot od RS485 RTU protocols i have done PCB design UPTO 6 Layers.I can send the samples with utmost quality and can support in Mass Production as well . Awating your positive response at the earliest for further proceedings

Hello, I have 6+ years of industry experience in design and development of embedded systems products. Presently I am full time freelancer based in Mumbai, India. I have few questions regarding your project. 1. What is supply used ? 2. What is relay rating ? Any specific relay already selected by you for this project? 3. Do you have cost limitation on BOM for the product? The board will have STM8 bit controller for communication and control purpose. It will have 5.08mm pitch terminals for each connection. The proposal covers only the design cost. Cost of making 5 prototypes( PCB cost + Component + assembly) is separate and to be borne by client. PCB fabrication takes at least 10 days and assembly will take 1 day. Hence , with complete firmware and testing it will take around 20 days + time required to mail the samples to you. Courier charges are also not included in the proposal. Also as you are based in Saudi Arabia, please let me know how to stay in touch and send you samples. Work on next milestone will commence only on receipt of payment for previous milestone. Prototype will be delivered on receiving the payment for 2nd milestone. Final firmware files will only be shared on receipt of full payment. Please inbox me for more queries. Regards, Shaikh Nasreen
