![]() ![]() Because of the large number of pin connections/jumpers that would be required you cannot go back from a MEGA to UNO setup. It is however possible to start with a 328/UNO configuration and later remove that chip and go to a 2568/MEGA configuration. Because the Atmega 2560 CPU is a surface mount chip, once it is installed on the board there is no way of going back to using the 328 CPU (without desoldering the 2560 chip from the board). The first thing you have to decide is which CPU you would like the board to be setup and configured for. Please note: this board can be driven by either the Atmega 328 or Atmega 2560 CPU chip but not both CPU's at the same time. In order to use and understand this S100 bus Atmega 328/2560 CPU board you should be fairly familiar with the Arduino hardware and software.Įxcellent vendors with much information about Arduino boards are " SparkFun.COM" and " Adfruit.COM" and of course Arduino itself. Here for a pinout diagram of the Arduino MEGA board. See here for a pinout diagram for the UNO pinout and The MEGA is somewhat similar but has more I/O pins. Two very popular boards are the Arduino "UNO" board and "MEGA".īy far the most popular "Shields" pinout is that found on the UNO. Arduino also provides a nice integrated development environment (IDE) for writing simple "sketch" code. The microcontrollers are typically programmed using a serial communications interfaces, including (USB) on some models. They are usually equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. Arduino board designs use a variety of microprocessors. Arduino boards are available commercially in preassembled form, or as do-it-yourself kits. The project's products are distributed as open-source hardware and software. Arduino is an open source computer hardware and software (Italian) company that designs and manufactures CPU board kits for the control A whole world of new hobbyists have in the past decade grown up around the "Arduino" boards. ![]()
