A DIY Arduino type hardware board based on ATmega644p Atmega1284p
This project is free and based on @MCUDude’s MightyCore which has awesome well designed kits for serious development with AVR’s.
Mightyduino is an Arduino with more memory than an Arduino Pro mini. It can use 644p (64k) or 1284p (128k) chips. Its voltage can be configured by U1 and the frequecy can be configured by the Murata’s ressonator (crystal). It has a power led and another one connected to pin D0. The push button performs reset. DTR pin can be used to external reset. The RAW pin is the input voltage <16v. The VCC pin is the regulator output and IC voltage, it can be loaded up to peak of 500mA.
Arduino board based on ATmega644p – [Link]
I am a hobbyist and learning experiments on Arduino NANO , UNO R3 , and made couple of projects on lcd displays and led cube 4x4x4 . I also have a Sanguino board with ATmega644P chip on it, but this board was never used because it was not detected by Arduino IDE and i didn’t try hard to solve this issue. But during recent lockdown it came again in my mind that i should try to use 644 chip for my next 8x8x8 led cube which requires bigger chip.I have tried downloading Sanguino software etc but no success. Please guide me how to make additional changes in Arduino IDE 1.8.13 for this purpose.
