The moment he hears an Arduino Mega in the line up he goes. so meets up with vendors and finds out what they do. The first thing he wants to do is impress. Then the company goes and gets in a new Wiz kid from now where and right out of college. The client side project team is happy with what you deliver and they have started using it. Those Teensy's are a lot smaller IRL than the site pics.Īnd GoForSmoke asked "who thinks Mega is hobby stuff.?" Teensy 3.x are also wow but count the pin holes and pads underneath and consider if you can connect to those pads without burning up or desoldering the chip. I can't say about total current draw from the Due but guess that it's no greater than the Mega board. The Mega pins max output is 40mA, they can deliver 5V 20-25mA steady. It also has 3.3V IO pins that max output at 10mA, meaning try to use half that or less regularly. The Due certainly is faster and has more RAM. I'm not sure about the Due but it does have stereo DACs and 13-bit ADC. You can also get smaller ATmega2560 breakout boards that look more industrial for your end product or make your own if you have the skills in-house. How it is "seen"? By whom? Is it because of the connectors? The Due has the same type, they're fine for custom cables but you can desolder them and solder wires directly to the board. Is the Mega slow already with the code you have? Is your code already non-blocking, no delays or wait loops?ĭoes it have enough pins to add the 4 RF24's? I know any debug is useful but how much of details does it provide ? How does the DUE interface with the IDE 1.6+ ? As easy as the Mega or.I can change the 4L x20C LCD with maybe a TFT touch screen or a graphics display unit.Somehow the UNO and Mega are still seen as Hobby boards.Compared to the Mega the DUE "sounds" more professional being a ARM product ( 32 bits too !!wow.).One interrupt channel to record pulses from flow meter.Īnd now as an additional requirement I have to add a 4 channel RF24 interface to the above setup.SD card for storing user plan and update actual file ( CSV format).
