Custom power supply module design

Hi sir I am electrical engineer . I will build your power supply module that will convert 220v to 3.3v D.C. I will work on proteus,easyeda like softwares.

hi, may i suggest HLK-PM03 use it ....this is quit simple solution ....i am wasting my bid because i believe you will consider me as PCB designer(i can help you with circuit too) ...whole full components in a single board will be good commercial purposes products....if u interested contact me

Hello I am 3.5+ years of experience in the IoT product development and designing we designed some product like IR Remote controlex, Smart Bin for the Government, Smart street light and many more small product we design we have in house team of IoT development, Product design, PCB design, Android, iOS, Xamrin, .NET, Magento, PHP. For the IoT and Electronics we working on the different framework and platform. Atmel, ESP8266, ESP32 , Nordiac, STM, NXP, PIC Microprocessor Board Raspberry pi 3, 3b+ 4, Beaglebone, NVIDIA Jetson Dragon board 410c, 820c, Customize the platform. we have experience in different kinds of sensor and communications module. 2G, 3G, 4G NBIOT GSM Module, GSM module, Sensor's Temperature Sensor Proximity Sensor Accelerometer IR Sensor (Infrared Sensor) Pressure Sensor Light Sensor Ultrasonic Sensor Smoke, Gas and Alcohol Sensor Touch Sensor Color Sensor Humidity Sensor Tilt Sensor Flow and Level Sensor etc.

Being an Electrical Engineer i have good and efficient skills in proteus and PCB Designing. I would like to complete this project because I have vast experience in power supply projects comprising of various types of step down transformers, rectifiers and capacitors. *** The reason for low is, I am new on this site.

I know which way you should follow u to find right equipment I have experience about the convertors invertors

Hi Team, We have a solution for converting 220v ac to 3.3v dc will manufacture and provide you with casing and customized logo of yours. Please contact me further if you are interested.

This was the part of my mtech project and I have good knowledge about it, you can hire me without any doubt. Relevant Skills and Experience Circuit design, technical knowledge

I work at hydropowerplant that produce power for costumers. I am junior electrical engineer but I have other skill such as designing, simulating, and other related with electrical power system.
