embedded trolley ID electronics

Hi, I hope you are doing well. I have expertise in embedded system programming and development. I have understood your project requirements. I have several options available to implement this project. I would like to discuss it in more details in chat. Please send me message for further discussion. Looking Forward, Khawaja

Dear Sir, Based on your description, At least we Need 4 wire, which is 12V supply, GND, and 2 wire for RS485 UART(because RS485 is better for long wire case, and I think your case need it). Every Trolley will have it's unique ID that can be set via DIP switch or something similar, So, you can reconfigure it. I will use arduino based microcontroller(I think Arduino Nano), max485 module, and One DC-DC buck converter module to converting 12V to 5V arduino needs. I will deliver all your requirement(Schematics, Gerber, and 2 working code to you). Also I will provide Video of working stuff. I have programming arduino since 2013 for various project, and personally I'm professional Electronic and firmware engineer, So this kind of stuff is my daily activity. Schematics and PCB design can be finished in 2-3 days, Gerber BOM List in 1-2 days, usually PCB production cost 7 days(I will use Chinese manufacturer), PCB delivery cost 3 days, assembling needs 2 days, and delivering video and working code I guess needs around 3-4 days, although this is simple project, but it will always needs a troubleshooting case, So, I propose that number of days. Lets discuss the detail over chat. Let me know how long your wire will be, and maybe the total number of trolley you have, so I can fit the DIP switch efectively. Best Regards, Rijal

Hi. I'm an electronic engineering student from Argentina. I've been working in freelancer.com for more than two years, and I've completed more than a dozen projects, all with good recommendations, you can check my profile. You will get from me the best effort to deliver a project that is up to your expectations and receive a good rate from your part. My bid consists of everything listed in the description. Please, if you have any questions, feel free to ask me! Regards, Esteban.

hello i have 4 years of experience in embedded systems. I have designed pcb and programmed micro-controllers(usart also) i have also experience in production. i have also worked on lcd displays with touch and also 7 segment displays i can also design the product very cost effectively so that it will easier to reproduce i have full confidence that i can deliver the project in time thank you raja chowdhury

Hi, Please see bid details, Regards, Nimrod. .

Hello, I am interested in your project and I hope to help you realize it, I am passionate about electronics and embedded development and I hope to share with you my knowledge and experience. I can do this work in 10 days max, if you wish, I would like to introduce you my proposal and my choices of components for your project and also the plan that I will follow for the design during a private discussion so, if you want to work with me I will guarantee you a good job delivered in the good deadline. thank you and good luck ^^

Hi, I am Embedded Firmware Developer. I have good experience in various micro controller with Embedded C. I would like to know about your exact requirement. Thanks.

I am an engineer in electronics, specialized in telecommunications, professor at the Andres Bello Catholic University in Venezuela where I count on the support of other colleagues

I had previously work with telematics Solutions based on IOT which is Vehicle Tracking System. Worked In Technology: 1. GPRS 2. GPS 3. Wifi 4. RTOS 5. FOTA 6. CAN 7. BLE 8. SPI 8. I2C 9. PCB Design 9. 32 bit Microcontroller 10. Raspberry Pi 11. Python 12. Arduino

I am well equipped with the knowledge and tools to solve this problem as soon as possible. i can create digital circuit solutions for this problem.

I can deliver this device. I have very good experience in embedded design. Please consider my proposal.
