Project details
We have developed an ESP32-based board family which we call 'miniPLC'. This consist of the main MCU PCB, which is the only part in this project offered, and additional PCB's connected via a backbone PCB using robust D-Sub 25 connectors. This allows a very robust assembly for shock-rich environments.
The device can be powered by a battery of 3.7V (1x 18650), via USB or by external 5V via a 5,5x2.1mm male jack.
There are extensions available (NOT included in this project tier, see my other project offers ) for HX712 (HX711), differential input, analog input 0-5V DC offset customizable (e.g. 1.5-4.5V) for common pressure sensors RS485/RS422/RS232 serial. Power outputs for relais up to 24V DC, up to 240V AC and more.
We address with this design fast prototyping for projects where the prototype has to see real-world conditions for proof of concept.
Additional custom I/O, digital and/or analog, are easy to add or change without requiring a whole redesign of the main components. Ideal for projects with unknown or unsure requirements.
It is as well fully Arduino IDE compatible, however, we do not provide support for the Arduino IDE. Our firmware will be done in Espressife ESP-IDF

Motor bike dashboard PCB review
Extremely capable and competent hardware architect. Went above and beyond in his review of the PCB Schematics - undertook my initial request, but then offered a solution outside of my initial remit that was far superior to what I asked and assisted my project greatly.

Electrical circuit design for custom camera array
I would highly recommend Ralph to anyone. Not only was he exceptionally skilled, knowledgeable and completed everything well within the project timeline but he went over and above to add features I didnt even think off. Also he was very pleasant to speak to and always had a positive attitude. Look no further Hire him!

Ralph was consummately a professional. He had an amazing ability to understand the problem space and was very aware of the pain point serendipitously. I only have nice things to say about him, will hopefully be working with him in the future! -Joseph A. Hazani
