PCB Design (Eagle): Small power supply 230VAC->3.3V

Hello Dear, We are a team of experts with a cumulative experience of more than 50 years in the field of embedded systems, programming, electronics and Prototype development. We offer services from project design to Engineering and from prototype to mass production. Our experts have experience developing complex solutions with 8-bit, 16-bit and 32-bit architectures with ultra low power. I have checked the details of your project. I discussed the same with my team. Luckily we did a similar smart switch for an Irish company a few months back . The design consisted of a micro SMPS (85V~265VAC to 5V) with ESP WiFi modem, Triac and some other parts. The whole design was made to fit into 20mm x 25mm x 20mm. We always prefer quality work with competitive price. Although we are new to freelancer.com but have a long history over GuRu and elance. We would offer you the solution (as per your demand) in just 100 Euro within 3 days. I would advise you to use the GPIO of ESP12 to trigger the Triac rather than using an MCU. If you have questions, please feel free to ask. Regards For Coherent Technologies Ch

Hi, I am a post graduate power electronics engineer and having very good industrial experience of 8+ years in R&D and project development. I am excellent circuits design, Regulated power supplies design with universal input to DC output, SMPS, DC-DC, AC-DC converters design, Battery management system, Battery chargers, UPS design, sine wave Inverters, solar grid tie inverters, Solar battery chargers and street light systems design from few watts to KW range using Buck, Boost, and Buck –boost, Interleaved boost/buck, Fly back Push Pull and H-bridge inverters. I have work experience to design from few watts to KW range meeting all compliances like EMI/EMC and safety standards UL etc.

Hello, I have been associated with Hardware design (Circuit / Electronics design), PCB design, Library creation and Library database maintenance, PCB Manufacturing, Component procurement, PCB Assembling and Functional testing for over 9 years. I have used various CAD/EDA tools for PCB design. I'm having good experience in Eagle. I will provide the PCB Manufacturing, Component procurement, PCB Assembling & Functional testing services too. I would like to take this up and are fully equipped to deliver the required files. So, if you'll give me a chance to take part to your work, I will respond in the same manner, handling you good quality projects, as soon as possible. I look forward to hearing from you! Wish you a nice day! Thanks & Regards, Karthik

A proposal has not yet been provided

I have 15 years experience in Telecom/Medical/Power/Aerospace Industries. Successfully completed many projects including 20W power supply for LED lights, 30W, 60W Power supplies for Aerospace. Interested to work on this project and ready discuss on further details and about my profile also

Dear Sir. it is a easy feature perhaps some issue with size. but you can not make coil less power. you must have 4000V isolation between phase & 3V3dc that complicate a little bit. special transformer. if high volum no problem, low volum you will have to paid 30000€ for CE merke and perhaps the same for UL my quote is only for start to prototype, all hours for CE test must be another task. Can you use QI charge system? bigger but easier to 4000V isolation not cheaper at all.
