I want a Freelancer to create workable schematic circuits of the following modules to be used with Arduino Mega 2560 and provide detailed BOM with digikey part numbers. I need the freelancer to help me find replacements for components if not available. I do not want any PCB design for them.
These are the list of Modules required.
1- 4 Channel 5V Relay Module based on Omron Solid State Relay
2- Temperature and Humidity Sensor based on Si7021 Chip with I2C interface
3- Barometric Pressure Sensor based on BMP280 chip with I2C interface
These circuits will be used with ATMega2560 chip micro controller 5V logic. If any of the modules requires logic shifting 3.3V to 5V. That should be included in the schematic as well.
I am electrical engineer and have done many projects on arduino and circuits solving and making embedded [url removed, login to view] will be pleased if you consider.
