Product Information

Arduino โปรดตรวจสอบข้อมูลเหล่านี้ให้ชัดเจน ก่อนกรอกข้อมูล เพราะใบกำกับภาษีไม่สามารถเปลี่ยนแปลง หรือแก้ไขได้หลังซื้อสินค้า The ATmega16U2 (or 8U2 in the rev1 and rev2 boards) firmware source code is available in the Arduino repository. The ATmega16U2/8U2 is loaded with a DFU bootloader, which can be activated by: Revision 3 of the Arduino board and the current Genuino Mega 2560 have the following improved features: The compact size, large I/O count and plug-in nature of these boards makes them ideal for some types of projects, especially where you want to permanently embed the board into the project. When coupled with our Mega 2560 Pro MCU Proto Board, it makes for a very flexible platform for larger projects.

|This was tested on both Uno and Mega2560. The the ethernet shield was plugged onto the Uno and Mega2560 during tests.

Technical Specifications

The voltage regulator allows touse upto18Vas aninput value, however wedonot recommend exceeding the recommended values aforementioned, since this can lead toexcessive heat and damage the device. USB B-port- The USB Interface is used to plug in the USB cable. This port can be used to power the device from the 5V supply and allows us to connect the board to the computer. The program is uploaded to the board serially from the computer through the USB cable. which 15 of the 54 digital pinouts are the PWM outputs, or basically.. how do i / you know that those are them? The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may become unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts. MISO-It stands for Master Input/ Slave Output. This data line in the MISO pin is used to send the data to the master.

The Arduino Mega Pro (Embed) CH340G / ATmega2560 board is based on the ATmega2560 microcontroller and the USB-UART adapter CH340 and is compatible with Arduino Mega 2560, with identical functionality. The board has a micro USB connector to allow you to connect the microcontroller to the computer and to use the Arduino IDE. You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISPor similar; see these instructions for details. The Mega 2560 has 16 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and analogReference()function. These super compact MP2315 modules provide up to 2A peak and 1.5A continuous current and are adjustable over the range of 0.8V up to within about 0.6v of the input voltage. If the input voltage is 12V, the DC-DC module can be set over the range of 0.8V to 11.4V. The module uses a single-turn potentiometer to adjust the output voltage, so expect to be able to hit within 5% or so of your target voltage. The Mega 2560 does not use the FTDI USB-to-serial driver chip used in past designs. Instead, it features the ATmega16U2 (ATmega8U2 in the revision 1 and revision 2 Arduino boards) programmed as a USB-to-serial converter.

Networking

In some cases, it may be useful to populate one of the three holes with single-row of female headers (or male headers) like found on a standard Mega 2560 which will allow breadboard jumpers to be used with the module. External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). These pins can be configured to trigger an interrupt on a low level, a rising or falling edge, or a change in level. See the attachInterrupt()function for details. Over my many years doing smart home (I started in 2004), I have developed my own library of code for Arduino processors and this includes functions to integrate it into my distributed Home Control System and connect numerous types of sensors. These ' slave processors' can then do clever stuff like local control, self-monitoring of performance, local signal conditioning and rate limiting, send warnings and errors, or host some functions locally.

|Radmon.org is free and always has been and in that sentiment, so is this code, as is all of my code that I share on the Radmon.org forums unless specifically stated.

Missing something?

The main input power has a reverse polarity protection diode in location D1. Our optional component kit includes a beefy 1N5822 Schottky diode that can handle up to 3A continuous current with a small voltage drop of only around 0.3V (typical). A standard 1N4001 or similar diode can be used if the larger voltage drop and 1A current limitation is not a problem for the application. The large 0.059″ D1 mounting holes will also accept larger gauge solid wire up to 16 AWG if no input diode is desired to avoid any voltage drop. The 3-hole and 4-hole patterns have 30 mil traces connecting them on both the top and bottom of the board for good current handling capability. LED – 3mm green LED. The shorter lead is the cathode, so the longer lead should be oriented to the anode ‘+’. Serial.println(CPM); // Print the current CPM to serial every interval if enabled - Much like the NetIO GC-10. The output of the DC-DC converter section has locations for an electrolytic filter capacitor C3 with 2.54mm lead spacing and a ceramic bypass capacitor C4 with 2.54mm lead spacing if it is desirable to add some additional output filtering.

there is a print on the board that SDA is pin 20 and SCL is pin 21 but those pins are digital pins while on genuine arduino boards the SDA and SCl are analog pins (4 and 5) or seperate SDA and SCL pins.looking at the interrupt part, it sounds like pinB is called.. which makes me think pinB needs to be an interrupt. Arduino Mega is well-suited for most of the guards used in other Arduino boards. Before you propose to utilize a guard, confirm the operating voltage of the guard is well-suited with the voltage of the board. The operating voltage of most of the guards will be 3.3V otherwise 5V. But, guards with high operating voltage can injure the board. Built-in DC-DC converter module to power separate power rail for servo motors or can power entire power rail
