ESP32-Based Wi-Fi Thermostat PCB Design -- 2
Budget: $750 – $1,500 USD
Description:
I am looking for an experienced PCB designer to create a custom Wi-Fi thermostat using the ESP32-WROVER-E-N8R8 module. The design must use SMD components and be no larger than 60x60mm. The thermostat will be powered by 24V AC, and it will control up to 4 relays handling 24V AC / 1A max.
Key requirements:
ESP32-WROVER-E-N8R8 module with program and reset buttons, as well as status LEDs for upload and operation.
Four relays capable of handling NO - COM 24 Volts AC / 1 Amp max. (pins defined by designer)
Rectifier bridge to convert 24V AC input to 12V DC / 3.3V DC.
Temperature and humidity sensor: Sensirion I2C SHT31-DIS-B2.5kS.
VOC sensor: Sensirion I2C SGP40-D-R4 (with a different address on the same bus).
SMD components and a rectangular PCB no larger than 60x60mm.
Ethernet interface with port( preferebly use LAN8720)
have an Waveshare 2.13inch E-Ink Display Module connected to the ESP32
Deliverables:
Schematic and PCB layout files in Eagle or another industry-standard format.
BOM with Digi-Key part numbers and all necessary information for ordering components.
Gerber files and any other necessary files for PCB fabrication.
A brief document explaining the design choices and any recommendations for assembly and testing.
Please provide a portfolio of your previous PCB designs, as well as an estimated timeline and budget for the project. Thank you!
