Arduino Mega and or Uno Prototyping Breadboard Holder and Power supply

thingiverse

All assembled parts for the power supply enclosure are joined together using #4 flat head sheet metal screws, with one notable exception - Top Plate Sm. This component is securely attached to the top of the enclosure via a strong adhesive bond. The P.C. Boards are firmly mounted in place with #1 and #3 type sheet metal screws. As for the power supply and breadboard holder, users have the option to either glue these components together or keep them separate - the choice ultimately rests with the individual. A weld-on adhesive specifically designed for use with PLA parts, known as #16, is utilized in the assembly process. Here are the key components required for the power supply: 2 units of a digital voltmeter gauge panel capable of measuring DC voltage and current within the range of 4 to 30 volts. 1 unit of a DC-DC constant current regulator capable of handling up to 5 amps of current. 1 unit of an adjustable buck-converter step-down power supply module, designed to operate within the voltage range of 1.25 to 30 volts and utilizing the LM2596 circuit design. Additional components include: A single panel mount socket for connecting DC power supplies, featuring a female connector design. 2 units of rotary potentiometers with 10-turn dials and a resistance value of 10K ohms. 1 unit of a two-position DPDT slide switch designed to accommodate a variety of applications. 4 units of red banana plug jacks used for electrical connections. 4 units of black banana plug jacks used for electrical connections. The following components are utilized in the breadboard and Arduino holder: A single solderless breadboard featuring 2 buses and 830 tie points, designated as MB-102. 1 unit of an UNO R3 development board, powered by the ATmega328P microcontroller. 1 unit of a MEGA 2560 R3 board, equipped with the ATmega2560-16AU microcontroller.
