We need a custom SMD PCB based on the ATMega328 (arduino compatible) the PCB need to following functionality: - Can communicate over RS485 (Modbus) (MAX485 chip) - Input power can be DC 12v-24v (Voltage regulator 7809) - Power LED (when power is on green LED) - Communication status LED, green (Can be set on or off by atmega) - Puzzle status LED orange or green (must be set by atmega, use only 1 digital pin) - Reset button - 1 Relay (Can be set on or off by atmega) needs to switch 12V 1.5A - 6 digital outputs as solid state relay needs to switch 12v 200ma - 6 inputs (add pull down) - Programming header pins - Please mention abrabra so I know you read the requirements - All the inputs, outputs, relay, 12VDC IN, RS485 need to be on screw terminals - Mounting holes; 1 in each corner. Can you suggest which components to use, article numbers and make the PCB design.

abrabra abrabra abrabra Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. (autopromotion^)) Easy task. Did a lot of pcbs like this. Do you need a usb-uart bridge to program it like arduino or avr-isp header to program like simple stand alone mcu? Give more info and lets talk. I will provide bom with elements you need. I prefer to do pcb design using eagle cad. It is most common. Result - cad files, gerbers for ordering pcbs, bill of materials.

Hello, How are you? I am an embedded software and hardware engineer who has enough experience in electrical and engineering field and embedded system design. I have rich experience in circuit and PCB design and have done similar projects before. We can choose appropriate components for this project as you request. - max485 for RS 485 communication - 7809 for power supply I think other components are simple and normal component so we can choose easily if you are interested in my suggestion, we can discuss the project in detail via chat. Thank you Alexander

Hi, I'm an electronic engineer with more than 5 years of experience in PCB design and Circuit design. I'm expert in Eagle cad and Altium designer for designing PCBs. I've read through your project description and I have good enough experience related to this type of work. I also have developed boards previously for Arduino compatible circuits. I believe you will be using ISP programmer for the programming the Atmega 328p controller. I would like to know if you have a basic design of the circuit. I can help you with SMD parts, sourced from mouser, or digikey. I'm confident about completing the project successfully and looking forward to hearing back from you. Thank you Anusha

abrabra Hi, I am an electronics engineer with 7 years experience of designing microcontroller based circuits. I can select components according to your specifications. I have some experience of designing PCB using KiCAD. My primary domain is firmware development so I can also provide you well documented code for your application if needed. In order to select components and design the PCB, I would like to know the following, 1. BOM cost: Required to select components within budget 2. PCB size: If mechanical casing has been selected/design, it would be essential 3. Number of PCB layers: Essential for manufacturing process (If developed inhouse for prototype, then multi-layers PCB will not be suitable). I look forward to hearing from you. Best Regards, Arsalan

Hello, I can use KiCad software to create the pcb and gerber files that you require for your device. I can deliver the complete Bill of Materials I can also help design a case for the device using Tinkercad, but that would take some additional days. What are the physical dimmesions that you require of the PCB? Do you require single layer, or it can use double layered PCB? Please let me know if you are interested on my proposal.

Hi. Sir I'm ready to make your PCB. As many required I/O Pin, I'll use 74HC595 to make 8 relay output and 8 input. I'll also use BD139 or FET to drive relay. I'd like to discuss it in more details. Best regards.
