Seeeduino Mega

Introduction Seeeduino Mega is a powerful microcontroller derived from Arduino Mega. It features ATmega2560 processor which brings a large number of I/O pins, as much as 70 digital I/O, 16 analog inputs, 14 PWM, and 4 hardware serial ports. Compared to Arduino Mega, we shrunk the volume of Arduino Mega by at least 30% and made it 100% compatible with Seeed Shield products. And as a member of Seeeduino series, Seeeduino Mega inherits deliberate details from Seeeduino, like selectable operating voltage(3.3V/5V), right angle reset button, and so on. Model:ARD121D2P ![enter image description here][1] Specifications Overall Specifications Operating Voltage: 5V / 3.3V Operating Temperature: -20~70℃ Input Voltage: 6-20V DC Current per IO pin: 40mA Flash Memory: 256k SRAM: 8k EEPROM: 4k Dimensions: 71*53*11.3 mm Power Jack: 2.54mm, 2pin JST Peripheral Features Peripheral Features are multiplexed with General Purpose Input/Output [GPIO] Pins, for multiplexing and assignment please check Pin Definitions. For more details on the alternate pin functions please refer to the Atmega2560 datasheet. 8-Bit Timers/Counters: 2 16-Bit Timers/Counters: 4 8-Bit Pulse Width Modulator (PWM): 4 Programmable PWM Channels: 12 Programmable PWM Resolution (Bits): 2 -16 Analog to Digital Input Channels (ADC): 16 ADC Resolution (Bits): 10 Programmable USART Channels: 4 On-Chip Analog Comparator: 1 Master/Slave SPI Interface: 1 Byte Oriented 2 -Wire Serial Interface: 1 Interface ![enter image description here][2] The following diagram illustrates the placement of important integrated circuits, indicator LEDs, connectors common to all Arduino based development platforms and the ones specific to Seeeduino Mega. Placement-diagram.jpg NOTES Label [5] The Seeeduino Mega uses a 4 Position mini-Type B Jack while the rest of the Arduino family uses standard 4 Position Type B Jack. The Arduino uses circular Power Jack. Label[9] The Seeeduino Mega uses a 2 Pin JST connector for the power supply while the rest of the Arduino family uses coaxial power plugs. Label[3] For the Reset button the Seeeduino Mega uses a an edge mounted push button while other Arduino based platforms uses a four legged tack switch . Yellow Labels are indicator LEDs. Blue Labels are mode selector and reset switches. Brown Labels are items that are common to the Arduino family; this makes the Seeeduino Mega compatible with most Arduino shields. Red Labels are the things that add the MEGA in the Seeeduino, the set includes additional ADC input pins and a bunch of bidirectional IO pins.
