4/12/2024 0 Comments Arduino mega pinout express pcbThe board was open-source, and the HW schematic was made available. On the board, a UART to USB interface chip was added to allow communications with an external PC, and the available pins of the microcontroller were made available to the user. Still, as in most microcontrollers, it has an integrated USART, several timers, ADC’s, SPI, digital IO’s that can also be programmed as PWM and external interrupt inputs. This is an 8-bit microcontroller with 8 KB of flash and 1KB of SRAM. Arduino hardwareĪrduinos originally had Atmel – now part of Microchip – AVR ATMega8 microcontrollers. This, and the ever increasing capabilities of Arduino compatible modules, is what makes Arduino so ubiquitous in embedded applications of moderate complexity. A person familiar with writing code on one Arduino platform can easily migrate to a different board.Īdding to the ease of transitioning to different hardware is the Integrated Development Environment, or IDE, which behaves in the same way regardless of the chosen hardware.įinally, there is a huge library base. This core is what makes Arduinos based on different microcontrollers behave in the same way. It is compiled, and linked along with the user application code, and then loaded. This core is actually not pre-loaded into the microcontroller. In this area, first, there is the bootloader that allows the user to download the application code to run on the hardware. There are many versions of Arduino compatible hardware, and the only things that are common among them is they all have a microcontroller and a USB port. Let’s take an integrated approach to understanding what makes an Arduino an Arduino in the first place.Īrduino can be viewed from many angles. With names such as Uno, Leonardo, Mega, Nano, Zero, Due and more, simply listing their specifications is not enough information to decide which you should choose for your given application. However, the proliferation of Arduino and Arduino-compatible boards, each with its own name, can lead to confusion over what Arduino is, and which version you should choose for your particular project. This can provide a less technically complex path to market for many makers.
