Best ESP32 Design Expert at your doorstep! Dear Client, I have read and understood your project details thoroughly, and I am super excited to work as they are an exact match with my skillset and experience. I plan to use an Atmel chip for storing data and I have certain queries as well as suggestions: 1. Why you need ADS1015 as ESP32 already have adc pins? 2. Are you using only WiFi as the wireless interface and not BLE of ESP32? Based on your answers I could save your product cost quite well With more than 5 Years of experience in PCB Design and Circuit Design in Altium, I can ensure you best quality work and before time delivery. Following is a brief list of expertise that I am carrying: 1. IOT products development 2. Microcontrollers based circuit design – STM32, STM8S etc 3. Smart Products like Smart watch - GSM/GPRS/GPS etc 4. Wireless Products - BLE/WiFi- ESP32/ESP8266/NRF24L01 5. Low Power Battery Products design – Rechargeable and Non chargeable 6. Power Electronics – Buck, Boost, Flyback etc Following are the examples of my projects along with their reviews: https://www.freelancer.com/projects/php/Sensor-modelling-Wordpress-Application/reviews https://www.freelancer.com/projects/pcb-layout/Hardware-design-for-small-GPS/reviews Let’s have a quick discussion for 5 mins where I would formulate a plan of action of how we shall take this project to the horizons of success.

Dear Client, I had came across your post for building the PCB Layout design and I have the experience in PCB layout designing for more than 2 years up to 4 layers of design. Had completed many projects with ARM, PIC & ESP controllers and also in signal processing. Also I extend my support with programming as I am experienced with uKeil, Atmel Studio and MPLAB as well. I can do this projects in efficient way because I have an experience in building an IOT device with ESP32 for home automation control. Deliverable: 1. Design Source File 2. Manufacturing GERBER files 3. 3D CAD of the PCB with all the components CAD assembled 4. Detailed BOM 5. Firmware Your project could be completed on time and submitted for your review. I will support you until your satisfaction. I am New to freelancing service but i had experience in working in an organisation, extremely interested to work on this project to showcase my skill. Looking forward to hear from you. Thanks, Kavin

Hi. I have over 10 years experience working on embedded products and have a very good understanding of what you are trying to achieve and how to do it. I would start by having a conversation with you to get a better idea of requirements. Your brief is very clear but there are always little bits of detail that come out from a conversation. My 20 days duration is an estimate at this stage based on the information you have given, availability of parts and my current work load. You project will have my full focus once I start working on it. I will keep you updated as frequently as you wish. Once completed I will hand over the deliverables and if you wish talk you through what I have done and answer any questions you might have. I hope to work with you on this project.
