Lenovo ThinkCentre M73 IoT Project Computer – Raspberry Pi Replacement

I suppose that in the implementation of IoT projects, we have two options for our servers, On Premise (Local Installation) or On Cloud (Hosted on the Internet), both have their advantages and disadvantages, but today we will talk about Local applications for our projects. For our local projects, I suppose that we implemented the world-renowned…

Modbus TCP/IP Slave Gateway to MQTT – ESP32 V.1

It’s been a while since I made a video or posted anything for PDAControl. I’ve actually been busy with other things and decided to get back to testing. I think the ESP32 is the quintessential microcontroller for testing; it has great features and I feel comfortable with it. There are other alternatives, which I might…
