Atmega328p altium library8/30/2023 ![]() ![]() For example, using DIP components may take up more space than their SoC counterparts. ![]() Characteristics like size or shape can also affect your choice of components. The physical characteristics of the board is also a key component in the planning stage. "How about the physical characteristics of the board?" A block diagram which is like the black box of your design is a great point to start from. Make notes of the software and hardware requirements of the board. For example, if your application requires some sound processing, you may use a microcontroller that supports digital signal processing (DSP). It could also depend on the functionality required. smart wrist watches) to those that are power-intensive. Other communication interfaces are like Controller Area Network (CAN) are available on STM32 chips " What kind of application is my board suited for? "Īpplication ranges from low power ones like wearables (e.g. In other to use other interfaces like USB you can check out the ATmega32U4 used in the Arduino Micro. The basic communication interfaces I needed at that time were SPI, I2C, UART. "What kind of communication interfaces would be required (e.g. Sometimes having a multi-core microcontroller gives you an upper edge in heavy processing. For heavy processing, I would recommend using some 32-bit microcontrollers like the STM32 series. You need to ask yourself these crucial questions: "What functions do I want to achieve with this board? Control or heavy processing ?"įor me, control was more important at that time than heavy processing hence 8-bit microcontrollers were perfect for the job. As an electronics hobbyist, I tried to find projects on how to build a custom development board but what I saw online was not complete so I decided to put the missing pieces together.īuilding a development board requires a great deal of planning and research. Some months ago I developed some interests in the ATmega 328P microcontroller but I did not know just what to start with. ![]() In order to make this tutorial less ambiguous, I have divided it into 5 major parts: In this write up I have assumed the reader has some electronics skills. Sounds exciting right? This set of tutorials will give you step by step guidelines on fulfilling these desires. Imagine having your own custom made development boards for rapid prototyping of projects. ![]()
