If only USBVCC was connected to UVCC, and VCC was disconnected from the 5V bus, would 5V still come out of the VCC pin?ĮDIT2: Ok, I think I see on the datasheet that 3.3V will come out of VCC if it is not pulled up by another source. Yes, its VCC is connected to the 5V bus.ĮDIT: I'm still confused about this though. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. The schematic you linked shows USBVCC connecting directly to UVCC on pin 31 of the Atmega16U2. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. The USBVCC voltage from the USB connector goes only to one place, the T1 FET switch. You must be looking at a different schematic then I am? The 16U2 chip has it's Vcc on chip pin 4 and it clearly wires to the board's +5V bus, not to the USBVCC bus. Now I see that it's connected to the MOSFET down below as well. Wir werden dieses Blinken jetzt selbst programmieren. Häufig blinkt diese Lampe schon, wenn man ein neues Arduino-Board anschließt, da das Blink-Programm zum Testen des Boards je nach Hersteller bereits vorab installiert ist.

Here are a few of the most important components and connectors to be aware of: Dimensions: The board measures 101.52mm x 53.3mm. Auf dem Arduino ist an Pin 13 bereits eine LED eingebaut (für Testzwecke). The Arduino Mega 2560 Rev3 is a large development board that is packed with a variety of components and features. Arduino may make changes to specifications and product descriptions at any time, without notice. Seems silly, but this is the only thing that made sense to me, because the 16U2 is the only thing I saw USBVCC connected to. Arduino Mega 2560 Rev3 Pin Headers and Components. Extended Projects You Can Make Your Own: Project List Skip to content. For some reason I had it in my mind that power came in through UVCC on the 16U2, was regulated there and came out of it's VCC port to supply the 5V line.
