The Arduino (Compatible) UNO R3 is a cost-effective, Arduino-compatible solution ideal for electronics enthusiasts, students, and prototypers. Designed around the ATmega328P microcontroller, this board delivers full UNO R3 functionality while using the CH340G USB-to-serial chip instead of the more expensive ATmega16U2. This makes it an excellent alternative to the original Arduino UNO without sacrificing performance or compatibility.

With full support for the Arduino IDE, this Arduino (Compatible) UNO R3 comes preloaded with the standard bootloader, allowing for quick plug-and-play programming via USB. The board features 14 digital I/O pins (6 with PWM), 6 analogue inputs, a 16 MHz quartz crystal, a USB connection, power jack, ICSP header, and reset button. Whether you’re just starting with Arduino or looking for a reliable, affordable development board, the Arduino (Compatible) UNO R3 is a versatile and essential tool for embedded system projects.

This metric fastener features a reduced head height of 1.5mm or less, allowing it to sit nearly flush against surfaces to prevent interference with moving parts in tight clearances. Its primary function is to secure mechanical components together without obstructing adjacent motion paths. It is designed for precise mechanical builds and structural assemblies with limited overhead space, such as securing brackets, plates, and V-slot wheels in 3D printers and CNC machines to avoid gantry or belt collisions. Additionally, it integrates into aluminium extrusion T-slot profiles and compact electronic devices to maintain space efficiency.

This wear-resistant black Delrin pulley kit mounts onto structural profiles and gantry plates, functioning as a belt-tensioning assembly in linear motion systems. Integrated core ball bearings provide friction-free rotation, allowing the flat-profile wheel to route the non-toothed backside of a timing belt to eliminate slack and reduce backlash without causing surface wear. Designed for V-Slot extrusions without requiring custom spacers, the component maintains stable tracking under operational loads. Typical applications include CNC routers, laser cutters, 3D printers, and automated conveyor rigs requiring precise belt alignment.

This solid-core roller kit mounts directly onto gantry plates and carriages, riding along V-Slot aluminium tracks to establish a low-friction guiding interface. The un-recessed configuration resists deflection under pressure, distributing structural loads evenly across extrusion channels during axial translation.
