Arduino uno in Bangladesh
- 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Arduino Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes.
- Uses Atmega328p SMD instead of the DIP Atmega328 of the standard one
- Stronger RESET circuit.
- Uses CH340 instead of Atmega16U2 of the standard one.
- Cheapest Arduino Uno for people on a budget.
