DESCRIPTION This project is to make a clone of Arduino Leonardo in a simple way.That is why the distribution of the pin does not match the standard Arduino (have to make many jumpers on the motherboard or use both sides). However, most Arduino Leonardo characteristics are maintained. The circuit is protected by an automatic reset fuse […]

As PCB part placements get denser, it’s necessary to add breakaway panels that add additional board material (edge rails) to accommodate the assembly process. Two parallel edges are required for a PCB to be processed in the SMT line. This is to prevent skewing through the conveyor system. Also, all odd shaped PCB’s must have

A new PCB design web application was released this last week called PCBWeb. The website states that PCBWeb is a free browser-based CAD application for designing and manufacturing electronics hardware. The tool is currently released in BETA and allows you to create a schematic, full circuit board layout, and then export to gerber format for

The upgraded part is only the PCB,the software remains the same as in original project which you can findat EasyDownloader V 1.1 Here you have a single side versionof PCB of the Easy-DownloaderV1.1 by WichitSirichote. The board is 10x4cm in a full size. That newPCB has some small modifications comparing to original scheme. It

The EasyDownloader V 1.1 , a Flash Writer for 89C2051/4051 which was designedby Wichit Sirichote, used a Double-SidePCB. I think, it’s difficult to make my ownPCB by myself. So that I decided to design a Single-SidePCB instead. My first prototype board wasmade using hand-writing with a permanent ink pen( see later in Figure 3).This page

Razen features an integrated schematic and layout editor with forward- and back-annotation. Editing library parts uses the same schematic & layout interface. 3rd-party part libraries can be imported and used directly from the editor. The interface, shortcuts and editing tools are customisable – from simple shortcut-key/display options to Python-scriptable editing tools. All projects are stored

our friend Vassilis decided to build his own manual Pick & Place machine to facilitate his work with 0402 SMD and other fine pitch parts: If you are dealing with tiny SMD parts (e.g. 0402 resistors and capacitors), a manual pick and place machine is a helpful piece of equipment for prototyping and small-batch manufacturing

The Arduino — and AVRs in general — have a wide range of power supply options ranging from around 1.8V to 5.5V. The choice of voltage is usually determined by the desired clock speed or power consumption requirements. The Arduino and its many variants have power jacks that allow connections from big, clunky “wall warts.”
