Introduction

Arduino is a very nice prototyping platform but, Although not very expensive, costs at least € 20 (25 USD). The CSEduino is the answer to a very low cost DIY Arduino like board.

The CSE stands for Cheap, Small and Easy to build.

With a very small budget of up to € 3.5 (5 USD) in parts it is possible to build this board with the required components. To be small some optimizations were made to the stripboard to accomplish its reduced size. The board is 4.5cm x 5.5cm. The circuit is adaptable to different requirements and it was made modular enough to be able remove the parts not needed and reduce its size even further. To be simple and easy to build I’ve used only THT - Through-hole technology. Avoiding SMD - Surface Mount Devices - components - as they are harder to solder and prone to errors. I’ve used the most common microcontroller used in Arduino Boards with THT  - the ATMega328P (in PDIP format). The components where soldered to a stripboard to reduce extra wiring.
