make me a PCB with I2C SMD for indoor air quality

Hello, My name is Andrei, i am a Romanian IOT Developer with a lot of experience in IOT projects and automatics . I have made a lot of sensors boards , for what you need here you will need a special I2C expandera , or direct connect to mcu - some of the sensors ar I2C , but some no . I deliver clean and clear solutions for the customers , according to the European regulations . I can work with all types of Microcontroles programming in C , C++ , Mikro C , CCS C , Atmel Studio , Arduino , gcc . Creating Schematics and PCB in Kicad , Eagle , EasyEDA and Proteus (+simulation). i have an workshop full of parts and the infrastructure to build PCB and test the solution end to end using special tools (Spectrum analyzers , oscilloscope , logic analyzers ) Derivable on the project : Wiring diagram for prof of concept . Schematic design PCB Design Gerber files for manufacturing MCU code explained every line - for testing prosperous As an additional service i can make you a full working prototype and ship to you. Regards, Andrei

Hi dear, I'm interested in the position of Indoor High Quality Sensor that you recently posted, particularly being of Hardware Engineering and Embedded Systems. I have experience in PCB design using KiCad, hands-on knowledge on schematic capture and multi-layer layout with signal integrity knowledge (high speed & power signals). Also, I have strong C/C++ skills and experience with microcontrollers(Arduino boards, STM32, PSoC and ESP WiFi Boards). Please see my portfolio. I look forward to hearing from you soon — feel free to contact me directly to discuss the position further.

Hello, I have read the details provided and i am positive i can provide quality work,please contact me to discuss more on the project deadline and some other few things

Hello, I would like to help with your project, bringing the required skills and experience. I believe to be highly competent in sensory, analog, RF, digital and power electronics design as well as embedded firmware for many microcontrollers. I have followed products from initial concept and prototyping to mass production. Some recent accomplishments are listed under my portfolio. The following are my initial notes: 1. it is generally not possible to use I2C to chain identical PCBs as you wish. For that, you need a different communication scheme/bus. 2. I2C is not suited for off-board connections, especially if the length exceeds some 30-50cm. Reliability suffers. 3. The requirements “SMD,cheap,reliable,I2C” cannot be met with the variety of sensor types you wish to include on the PCB. 4. Your budget is ridiculously low. Thank you for the opportunity, Best Regards -v8volante PS: I live in Italy, after 10 years in Silicon Valley. I speak fluent English.

Dear Sir, I am embedded system developer. I have expertise in designing miniature circuits. I can provide you a perfect hardware design for your project. Best Wishes

Hello sir! I already have a design that almost completely meets your requirements (see the portfolio, "air quality board" please). I am ready to adapt it to your needs as soon as possible. PS price is indicated for design only.

I can made I2C communication in Arduino or PIC microcontroller. I also made my designs on KiCAD. I can do what you want.

Hi. I'm an electronic engineering student from Argentina. I've been working in freelancer.com for more than two years, and I've completed more than a dozen projects, all with good recommendations, you can check my profile.
