Please read this carefully if you want me to consider your bid. Bids that do not answer the questions below will be ignored. I'm looking for someone who can design a PCB with a large number of independently addressable RGB LEDs. I have attached some files with a design reference (vector and image). The project consists of a multi-digit 7 segment display as well as text and logo. In the attached file, you can see the outline of where the LED's should go (the grey filled area). These grey areas are where light can go through, with a mask being applied to everything else. I'm open to suggestions on what to use - MAX7219 is fine or you might have some other ideas due to the large number of LEDs (especially since the LEDs are RGB). REQUIREMENTS: We'd probably like to use this led: [login to view URL] Ideally this will be a 2 layer PCB unless you think that isn't possible. Ideally there will be a minimum number of vias. The logo should use approximately 128 independently addressable RGB LEDs. The other elements should be approximately the same density (e.g. 2 LEDs for each element of the 7 segment display). Ideally whoever does this can also write the basic codebase - calling a REST API and updating numbers on the display based on the result, a couple of example light displays for the logo. BIDDING: When submitting your bid, please specify: 1. Do you plan on using the MAX7219 or do you have something better in mind or something else you have worked with before? 2. Do you want to write the code as well or just do the PCB design (this can be a separate quote)? 3. What software will you use for PCB design? We use KiCad so if you can use that it's better but not 100% necessary 4. How long do you think it will take you to do the PCB design? 5. Do you think you'll be ok being limited to 2 layers? Thanks!

Hello, Have a nice day. We will design, built and ship the prototype of fully working hardware. We will be taking care of firmware development, PCB designing, PCB printing, components sourcing, PCB assembling and enclosure making. We can use Ki-CAD, EAGLE CAD, Altium and Proteus. We will use Proteus at first stage to simulate the hardware later on if every thing goes well we will be using that for PCB design else we have other choices. As far as MAX7219 is concerned, we can think about low cost and fast responding ICs, choice of micro controller can be altered (we can use ARM instead of AVR), ESP32 can also be used in place of micro controller. All these details can be sorted out. Making in house PCB( double sided, 10 mill track width, 0.3mm via size ) is not a big problem for us. Please feel free to contact us and to discuss further. Best Regards, Shahbaz.

Hello! I'm an electronic engineer with solid experience in PCB design. I work with Eagle and Altium. I will ask your questions as best as I can with the information you submited but I need to chat with you to clariffy some points. When you need to drive adresable leds the next three leds are usually used: WS2812B SK6812 APA102C Then you do not need any other driver and the effective space on the PCB is reduced as the number of tracks. In this case, with a two layers board should be enough. Adittionally I dont understain how do you want to manage the LEDS. I think a microcontroller should be putted in the same board (any special?) but how do you change colours and brights? Anywhay, I will do the code too. Finally: wich is the size of the logo and text? If you could contact me by chat to clariffy this points, I can give you an acurated bid and delivery time. Regards.

Hello, Greetings of Peace! Thanks for inviting me to the work. By RGB LEDs, I think we can also use WS2812, which is also a programmable led. and for the remaining, we can use either MAX7219 or MCP23016, depending upon the requirements. I can also write the code for this. I have already done something similar where I controlled more than 100 LEDs, individually addressable. I work in Eagle and I am sure to get this done in 2 layer PCB. I would like to discuss your requirements in detail. Please get in touch. Best Regards, BK Krunal

Hi, I'm an electronic engineer with more than 5 years of experience in Arduino based embedded systems design. I also have designed custom Arduino boards as well. which your design matches the same profile since you are using 328P Atmega chip. Also with that, I'm happy to say that I have worked on ESP8266 as well and I'm completely experienced with how to embed ESP8266 module in a PCB. Regarding your project, I have one suggestion. Since your LED for seven segment displays are also same as Addressable LED sizes, (just as WS2812B LEDs) we can use them. This also eliminates the use of extra uses using different chips on the board to manipulate 7-segments. We can handle the numbers from software we write. If you need I can get it done for you in a different milestone. 1) As I suggested we can continue to use Addressable LEDs so we can eliminate this. 2)Yeah. I'm an arduino based programmer as well. Also I have been working for many projects for development. I can write the code on a separate milestone. 3)Usually I use Eagle CAD, but if you really need, I can use KiCAD. 4)I think I can get the PCB done in 1 week, then programming would take another week or so. 5)yeah. Specially if we go with addressable LEDs we can keep it to two layers easily. I'm very confident about completing this project successfully and looking forward to hearing from you. Thank you Anusha

Hi, Good day! Please see my responses below. 1. Do you plan on using the MAX7219 or do you have something better in mind or something else you have worked with before? A: Since the LEDs are RGB, I'm planning to use something better and cheaper. I will suggest TI TLC5947. 2. Do you want to write the code as well or just do the PCB design (this can be a separate quote)? A: Yes l, I want to write the code but I need a hardware to test it. 3. What software will you use for PCB design? We use KiCad so if you can use that it's better but not 100% necessary. A: I prefer KiCAD. You may check my portfolio for sample designs. 4. How long do you think it will take you to do the PCB design? A: i will target 15 days to complete it. 5. Do you think you'll be ok being limited to 2 layers? A: Yes, but it would be better 4 layers. Or we can make by modules in 2 layers with cables to interface them. Thank you Lawrence

1. Do you plan on using the MAX7219 or do you have something better in mind or something else you have worked with before? Ans: Use WS2812B LED's, I am not seeing any benefit of choosing "Semi-Dumb" LED's You mentioned. 2. Do you want to write the code as well or just do the PCB design (this can be a separate quote)? Ans: If above is considered than yes. (this WILL be a separate quote) 3. What software will you use for PCB design? We use KiCad so if you can use that it's better but not 100% necessary Ans: Eagle. 4. How long do you think it will take you to do the PCB design? Ans: 30 days 5. Do you think you'll be ok being limited to 2 layers? Ans: Yes I think it's ok (in my first perception). But at cost of skipping "minimal Via" criteria. I have more than 5 years experience in embedded system and PCB design with eagle and altium design software . so i can do your job within a time limit with your satisfaction.

HI Sir I can complete this project. Answers 1. Do you plan on using the MAX7219 or do you have something better in mind or something else you have worked with before? Yes I have work with MAX7219 & other depends upon they way you want to use serially or parallel light them up 2. Do you want to write the code as well or just do the PCB design (this can be a separate quote)? I will do both Code+PCB too 3. What software will you use for PCB design? We use KiCad so if you can use that it's better but not 100% necessary I can use Altium + Eagle + Proteus if you have other i can design in them too. 4. How long do you think it will take you to do the PCB design? 2-3 days at max 5. Do you think you'll be ok being limited to 2 layers? yes depends upon complexity.

I worked with MAX7219 before. I can use it in this work. I can write code and design pcb. I prefer Eagle to design pcb. I think design pcb and code in 15-20 days. I think 2 layers are enough.
