PRODUCT DESCRIPTION

This microcontroller board is based on the ATmega328 MCU 5V 16MHz CH340 Type-C. It is similar to the Arduino Uno in terms of functionality, but it is smaller in size. It does not have a DC power jack and it uses a Type-C connector instead of a standard USB connector.

You can program this board with Arduino programs and the Arduino IDE. This board uses the CH340G USB interface controller.

You can power this board in three ways: through the USB connection, a 6-12V unregulated external power supply (pin 30), or a 5V regulated external power supply (pin 27). The board automatically selects the highest voltage source as the power source.

Features: 

1. CH340G USB bus converter chip replaces FT232RL
2. Operating Voltage(logic level): 5V
3. 8 analog inputs ports: A0 – A7
4. 14 Digital input/output ports: TX, RX, D2 – D13
5. 6 PWM ports: D3, D5, D6, D9, D10, D11
6. 1 pair of TTL level serial transceiver ports: RX / TX
7. Uses Atmel Atmega328P-AU MCU with bootloader installed
8. Support USB download and Power over Mini-B Mini USB connector
9. Recommended input voltage: 7V – 12V DC on pin 30 or 5V on pin 27
10. Maximum input voltage limits: 6V – 20V
11. Supports ISP download.
12. Supplied with connector pins (headers), not soldered to the board for user flexibility.

Descriptions: Arduino Mega 2560 PRO (Embed) CH340G ATmega2560 16AU Development Module Board For Electronics Projects DIY

Arduino Mega2560 Pro is a scaled-down version of arduino mega. It has more input output and memory than Arduino Uno, and its smaller size than mega eliminates the problem. It has usability for almost all of your projects. 16 MHz atmega 2560 microcontrollers are used in the product. It can be connected directly to the PC via the CH340G integrated on the board. You can program it with the Arduino IDE via the com port on the PC

Features:

• The smallest Arduino Compatible breakout board measuring less than 1 square inch!
• Support for the Arduino IDE 1.0+ (OSX/Win/Linux)
• Power via USB or External Source: 7V – 35V DC (12v or less recommended)
• Automatic selection between 5V USB and External Source for Power
• On-board 500ma 5V Regulator
• On-board microUSB port for easy programming & power
• 6 I/O Pins: 2 pins (P3 & P4) are tied to USB (This means if your program actively communicates over USB they will be in use. If your program does not actively communicate over USB you can use all 6 I/O pins after programming via USB)
• 8k Flash Memory (about 6k after bootloader)
• Communication Protocols Supported: I2C and SPI T
• PWM on 3 pins (more possible with Software PWM)
• ADC on 4 pins
• Power LED and Status LED on-board

Pinout:

• I/O Pins:
  • PO: Pin 0, AREF, SDA
  • P1: Pin 1, PWM, DO
  • P2: Pin 2, D/A, SCK
  • P3: Pin 3, D/A, USB
  • P4: Pin 4, PWM, D/A, USB
  • P5: Pin 5, D/A
• Power Pins:
  • VIN: External Power Supply: 7V – 35V DC (keeping this under 12V is recommended to avoid unnecessary heat)
  • GND: Ground 0V
  • 5V: Regulated 5V (If you have a regulated 5V power supply use this pin, otherwise use the VIN external supply which goes through the voltage regulator on board and does not go directly to the chip)

The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with bulky external USB interface.

This tiny little board does all of the neat-o Arduino tricks that you’re familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere. If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin on not VCC.

Features Pro Micro ATMega32U4:

• ATMega 32U4 running at 5V/16MHz
• Supported under Arduino IDE v1.0.1
• On-Board micro-USB connector for programming
• 4 x 10-bit ADC pins
• 12 x Digital I/Os (5 are PWM capable)
• Rx and Tx Hardware Serial Connections
• Our Smallest Arduino-Compatible Board Yet!

Uno R3 is the clone one of the latest version of Arduino Uno with an on-board CH340 usb – serial converter chip. Even there are some little differences respect to original one, it is almost the same in terms of usage and software. This provides you a cheaper opportunitiy to get started with Arduino boards.

The microcontroller model of this board is the same as the original one (Atmega328). The only difference between microcontrollers is ther package. Original one has a DIP package but the clone one has SMD package microcontroller. We offer working warranty for this product as we offer the for the original one. so, you may trust to use this cheaper clone board. Untill now, we have not seen any problem of using this board but, if you see any problems we offer ralunda or exchange too.

Despite being a clone one, there are a pin group (4x GND, 2x 5 V, 2x 3.3 V, 1x RX/TX, 1x SCL/SDA) near to the crystal oscillator and there are external pin holes allow you to solder male headers on the board too.

Uno R3 Improved Version CH340 Chip for Arduino

SIM868 GSM/GPRS/Bluetooth/GPS Development Board Without Antenna

It is a small, complete, and breadboard friendly.

It has everything that Diecimila/ Duemilanove has (electrically) with more analog input pins and onboard +5V AREF jumper.

Physically, it is missing the power jack. The Nano will automatically sense and switch to the higher voltage source of power, there is no need for the power select jumper.
