Have you ever wanted to build your own Arduino ... design your own board, your own variant or even a completely different project. [Pratik Makwana] starts by showing how to design the circuit ...

While this may be controversial, there are sufficient battery power sources for this design to work (4 cells of AA or AAA NiMh batteries or a mobile phone charger). The Arduino Nano uses a ...

This article follows up by presenting a simple circuit for a frequency counter derived from the GPSDO schematic. As shown in Figure 1, we reuse much of the previous design including the power supply, ...

The Make build here uses the Really Bare Bones Board schematic as influence to make a low-power, tiny Arduino board. It guides you through building the schematic in EAGLE, laying out the board ...

The KiCad freeware schematic capture tool is used to configure an active circuit breadboard. Library cards with Arduino Nano and protoboard ... A good overview of the design process, using a ...
