arduino leonardo pinout
This is a 16 megahertz chip on in it’s. A slightly different chip to the uno is actually a very similar form factors of the you know, but it’s actually, a little bit different in quite a few ways in particular, has a very different chip on board. Atmega 32. You four on board. Instead of the atmega328, it runs at 16 megahertz, which is the same as the you know: 5 volts same power requirements 7 to 12. Volts it’s got built in little. Your DC socket here or you can run it via. The USB USB type is a micro type. 2B, so it’s, a very, very small, USB port and will automatically change over between those power sources recommended is 7 to 12 volts. As your incoming supply power, it will just about get by on between 6 and 20 volts DC you’re going to make some sacrifices in stability or capability in some respects. So I recommend sticking between 7 to 12 volts. It has 23 digital pins now, which is more than the you know, 7 of which can do PWA get PWM again a little bit more than you know. Software internal resistors pull ups, so you can trigger that by your code. If you need to, if you’re, connecting up switches, for example and 12 analog inputs, of which 2 are dedicated and 10 or as opposed to the you know, which only has six shared analog inputs, so that there’s a lot more pin availability from this from the Leonardo Over the you know, in the same form, factor essentially interrupt pins available again more five five into it pins available, and apart from that ram memory, wise you’ve got the same amount of sketch grammar at 32 kilobytes and a little bit more program.
Memory. You’Ve got two point: five kilobytes from the Leonardo, rather than two on the unit and EEPROM as with most of these products, is one kilobyte emulated. Usb chip on the Leonardo is done by the main CPU, rather than only you know, you’ve actually got there. The very basic USB chip this can be leveraged to emulate other USB form factor devices such as MIDI and that sort of thing so there’s a there’s, a TampR do which allows you to load teensy bootloader and to USB emulation onto the Leonardo. And so you can create very easily USB devices that sort of thing Micro, type B, USB port we’ve, already covered with 500 milliamps of over current protection. It has a USB serial and the UART TTL five fault serial. I squared C on pins two and three SPI via the ICSP header right here, and it is sixty eight point, six mil by fifty three point: three mil, which is exactly the same as the you know: it’s got the same size it’s an it’s, an Leonardo par 3, this particular one and it’s it’s got fairly good shield compatibility with you know shields. There are some little pin out differences that you might need to take into account. So please do check before you buy shield, for the Leonardo make sure that you’re going to be able to make it work. It won’t work with everything. So if you’re thinking of making an Arduino product purchase, excuse me please consider going over the paint Tech Talk in the UK to make your next purchase.
