A miniature version of an Arduino UNO board made in Sri Lanka for small applications with removable ATmeega328P chip. This board doesn’t contain a TTL chip. Therefore, a separate USB to TTL module is needed. The FTDI USB to TTL module can be directly pluggable to the development board.

Optimus Arduino UNO Mini Development Board specifications:

• Compact design.
• Comes as a DIY-kit.
• Suitable for applications which has smaller spaces.
• Removable chip.
• Operating voltage is 5V.
• Reversed polarity protection for the chip.
