UNLIMIT3D - ESP32-Breadboard Family (3 in 1)

Hello world!

I'm Ivan, creator of UNLIMIT3D.

Surely, if you are electronic you will have realized that until now there was no "protoboard" capable of containing a development board based on the ESP 32 microcontroller, allowing the connection of its pins on both sides. This happens with all commercial breadboards, being mandatory to have to use two breadboards to make a simple circuit with that microcontroller (which can be cumbersome and confusing). This was happening until now, as I have taken the boldness to design a specific breadboard capable of ing an ESP 32 development board, as well as ing the other models of "Arduino" type development boards, such as: Nano, Micro Pro, Pro Mini, ESP 8266 and even Raspberry Pi Pico.

The ESP32-Breadboard-Mk2,ESP32-Breadboard-Mini-Mk2 and Breadboard-Mini-Mk2 models are used in the same way as any commercial breadboard and were designed respecting commercial standards.

The ESP32-Breadboard-Mk2 model allows to place a power supply to supply power to the voltage buses and at the same time power the ESP 32 independently with respect to the rest of the circuit (second half of the board). To house the ESP 32 it has 220 connection points divided into 110 points on each side of the circuit (22 x 5 point matrix on each side). The first half of the ESP32-Breadboard-Mk2 is internally separated from the second half as far as the power buses are concerned, i.e. to communicate these power buses from the first half of the board to the second half it is necessary to bridge them. The second half of the ESP32-Breadboard-Mk2 consists of independent power buses from the first half and has 330 connection points (divided into two 33 x 5 point arrays on each side) for placing components, transistors, displays, ICs, potentiometers, etc.

The ESP32-Breadboard-Mini-Mk2 model with 220 connection points allows the ESP32 to be powered in tight spaces. It also serves as a for the ESP32 development board when connecting it to the computer to load the program, without the ESP32 running loose on the table or on the work desk.

The Breadboard-Mini-Mk2 model with 330 connection points allows you to run your tests and projects in confined spaces. It also serves as a stand, when connecting a microcontroller to the computer to load the program.

Once you print any of the models, i.e. ESP32-Breadboard-Mk2, ESP32-Breadboard-Mini-Mk2 or Breadboard-Mini-Mk2, you must remove the metal brackets from any commercial breadboard and place them inside the holes of the printed model. In the channels corresponding to the power buses for the ESP32 section you must place individual brackets and solder them. After placing all the brackets in place, you must glue the back cover using glue.

Includes optional anti-skids to place under the breadboards you print.

It is very easy to print in PLA.
