Need to develop an IOT product that Must Have: 1. Ethernet TCP/IP 2. 8 Digital inputs (24VDC) , two of them for pulse counter(1KHz) 3. 4 LEDs Output for indication 4. RTC 5. EEPROM 6. Battery for short term Backup only (not needed for low power mode) 7. RS 485 (2Wire) 8. Detection of Power Failure 9. 2 Channel Analog inputs (0-10V or 4-20mA) 10. USB interface for configuration Preferred to have 1. 2 Line Segment LCD display( if this is the case then LED outputs will not be needed) 2. WiFi interface 3. 2 Port on-board switch to make Daisy chain Software: We need basic functions to be implemented: 1. MQTT over Ethernet TCP/IP: Solution will provide functions to connect, publish , subscribe. There will be one callback function, that will be called as soon as we receive any messages for the subscribed topic. [login to view URL] soon as there is a power failure detected the data will be written to EEPROM 3. Developer needs to provide interfaces for all IOs 4. on RS 485, Modbus Master stack Deliverables: 5 protoytypes, BOM, PCB design, Schematic, Application debug support

Best Embedded Hardware Expert at your doorstep! Dear Client, I have already designed countless Hardware on IOT products and am 100% confident to provide quality results I can develop the IOT product Ethernet TCP/IP, RTC EEPROM, . RS 485 2Wire, USB interface for configuration as per your requirements I couldn’t stop myself from bidding after going through the description as they are an exact match with my skill set and experience. I have extensive experience in IOT product based on Hardware and know all the intricacies required to get the job done with perfection. With more than 15 Years of experience in PCB Design and Circuit Design in Altium, I can ensure you best quality work and before time delivery. Following is a brief list of expertise that I am carrying: 1. IOT products development 2. Microcontrollers based circuit design – STM32, STM8S etc 3. Smart Products like Smart watch - GSM/GPRS/GPS etc 4. Wireless Products - BLE/WiFi- ESP32/ESP8266/NRF24L01 5. Low Power Battery Products design – Rechargeable and Non chargeable 6. EEPROM, Ethernet TCP/IP Please answer the following questions: 1 What are your future plans with this project? 2. Are there any specific market standards like CISPER you are aiming? 3. What will be ambient temperature of this product? Let’s have a quick discussion for 5 mins where I would formulate a plan of action of how I shall take this project to the horizons of success. Regards Avi Tech Experts Quality is never an Accident

I can implement your project. I have a huge experience in IOT boards. I have multiple ethernet based industrial proven designs, that are work in huge quantities. I can make the prototype board with the embeded software. I think an STM32F407 MCU would be the best choice. It has ethernet and usb support and plenty of I/O. An addition ESP8266 would be a good WiFi module. I have a few questions: -Digital inputs sample frequency, or only edge detection? -Board supply voltage? -Does the battery need onboard charger circuit? I think I can implement all your requirements. PM me for more info.

Hello, I am an embedded developer with 5 years experience in automotive industry working for a lot of embedded projects. It seems a nice project, not very complex. For the project we can use different microcontrollers, which I can present to you depending on your deeper needs. We will have to make some architecture documents to describe the desired functionality ( this details can be estabilished only after your decision ) I am waiting for the decision. Thank you!
