ES32D26 FAQ

I am a manufacturer of small machines and other solutions at an affordable price.

Not everything you produce is good.

Can you produce a version suitable for industrial use?

The best board for you right now is the ESP32DevKitC ESP32-D26.

What I need:

Few analog inputs and outputs are needed—two of each suffice. Analog inputs are hardly used in industry anymore.
Unused pins are left available for transmissions other than RS-285; the ES32D26 board is a good example, where these pins can be allocated for I2C or TTL UART to communicate with an HMI display.
In Europe, PNP inputs and outputs are used; encountering NPN components almost always causes problems, as many sensors in the EU are PNP.
More 24 VDC inputs and more 24 VDC digital outputs; additionally, there can be eight 5 VDC PNP outputs.
We try to avoid installing relays, as they are prone to failure and difficult to replace.
 

You won't gain much traction in the EU unless you adopt solutions like these. Your devices spark interest, but they also complicate the implementation of the control system. That’s all for now—let me know what you think: would you be willing to produce boards like this, and what else do you need to know?

Hi , we can custom for you
