ESP32-S3 IoT Schematic and PCB Design
Budget: $250 – $750 USD
I’m looking for a designer who can take an ESP32-S3-WROOM-1-based concept all the way from schematic capture through to a production-ready PCB. The board will integrate a Wiznet W5500 for hard-wired Ethernet and must expose several data-acquisition ports: dedicated digital inputs, UART/SPI/I2C headers, plus one custom input block whose exact signalling I’ll share once we start. The power will come from an external supply or POE. In additon we need an internal LiPo battery backup and charger.
We will be using schematics and proven designs from existing ESP32-S3 development boards. These are from WaveShare, Olimex, and Lilygo. We will be using bits and pieces from each of their existing schematics.
Mechanical fit is important. I’ll supply STEP files and mounting details for the enclosure, so the layout needs to respect that outline while keeping RF performance and Ethernet magnetics in mind.
I expect:
• complete, tidy schematics (KiCad, Altium or similar) (KiCad prefered)
• a manufacturable PCB layout matched to the enclosure, This may occur in two phases. One a prototype phase using an off the shelf ESP32 module then add the ESP32 function to our board.
• Gerbers, pick-and-place, BOM and 3D step files,
• brief design notes so my firmware team can bring the board up quickly.
If you have prior experience marrying ESP32 modules with W5500 and can balance signal integrity with tight mechanical constraints, let’s talk timing and any questions you may have.
