Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. I can help you with your deal and since im new one here I can do it cheaper then anybody. I dont understand what you mean with "occupancy", but it doesnt metter ^) Can do both either homemade prototype( faster), or order PCB production and do cute one. Ofc my bid is only my work and doesnt include any additional expenses like parts, PCBs, shiping. But parts and PCBs are much-much lower then bid. And Im little busy now, can start in a week minimum and need up to 2 weeks. Plus PCB manufacturing waiting if needed.

Hello, My name is Stefan, and I work at a company as an Electronic Application Engineer and I believe that I can help you with your project. I can work on schematic design, provide PCB layout, BOM, also work on firmware (if needed), develop and test the prototype. (basically I can work on the entire process). I look forward to a more detailed discussion about this project, and if you could give some additional information, it would be great. Please note that price time period that I put in my bid are just preliminary, and as soon as we set the project details, I will be able to give you a better estimate. Depending on the complexity of the project, I could finish the work sooner. I appreciate communication when working as a freelancer, and I want to assure you that I will respond to your question/ ask questions regarding the projects any time when it's necessary, because I believe that good communication leads to positive results for both sides. I am not an arrogant person, and I won't bid with a large amount of money, I want to prove myself to an employer first, and then if he appreciate my work, continue in future collaborations. I look forward to hearing from you! Wish you a nice day
