Need more pins, ports or breakout options than a bare UNO gives you? The Arduino UNO R3, Leonardo Multifunctional Expansion Board is built to sit on top and add exactly that, and Tech Depot India has it priced at Rs 155 — see the Arduino UNO R3, Leonardo Multifunctional Expansion Board listing for stock and details.
What is the Arduino UNO R3/Leonardo Expansion Board?
This is a multifunctional expansion board designed to work with both UNO R3 and Leonardo boards, stacking on top to extend what's available on the base board. As the name states, it's built to add functionality rather than replace the core board — you still need a UNO R3 or Leonardo underneath it.
Full compatibility and layout notes are on the product page, which is worth a look before you plan your wiring.
Arduino UNO R3, Leonardo Multifunctional Expansion Board projects — what you can build
