Availability of PCB for ESP32-Based Industrial IoT Sensor Node

[Aria James]

Hello everyone,

I’m working on an Industrial IoT sensor node using an ESP32 for real-time data acquisition and wireless communication. The project involves integrating multiple sensors (temperature, humidity, vibration) with the ESP32, and I’m designing a custom PCB to streamline the connections and improve reliability.

I wanted to ask if there are any recommended sources where I can get pre-designed PCBs for similar ESP32-based projects, or if I need to manufacture my own via services like JLCPCB or PCBWay. Have any of you come across open-source PCB designs for such applications?

Any guidance or recommendations would be greatly appreciated!

Thanks in advance.

Espressif provides hardware design guidelines and schematics for their devkits. Your sensors will likely have a typical design in their datasheets. If you do a bit of googling, you can find lots of schematics and gerber layouts.
If you are soliciting for help, good luck. Maybe try the hardware forum instead of Arduino.

You can assess datasheet to view the circuit diagram and understand how to start to use their module: https://www.espressif.com/sites/default ... eet_en.pdf
Often they provide simple power supply instructions and a startup reset circuit design, though you'll need other circuitry to solve the 3V3 power supply problem (e.g. you can use an LDO to get 3V3 voltage from the TYPE_C port).

If you need some example projects (all schematics, BOM, PCB), you might want to look on some open source hardware forums.
Ordering PCBs from JLC is a good option, and if you want convenience (don't want to do PCB file conversions or schematic design, etc.), you might want to look at this forum （though it's in chinese）：

Thanks for the reply! I’ll definitely check out Espressif’s hardware design resources and take a closer look at sensor datasheets for reference circuits. Also, good call on posting in the hardware forum might get more targeted help there.

Thanks for the additional info! The datasheet from Espressif will definitely help, and I’ll look into using an LDO for the 3.3V supply. I appreciate the suggestion on open-source hardware forums and the link to OSH Whub, I'll check it out. Also, ordering from JLCPCB seems like a solid option for PCB manufacturing. Thanks again for the help!
