Arduino UNO smd v3. Vs arduino uno v3 .What is the difference

The difference between the two Arduino UNO module is the ATMEGA MPU chip. The Arduino UNO uses the DIP version of the chip and the ARDUINO SMD version uses a surface mount ATMEGA chip. Function wise, there is no difference. The only advantage on using the ARDUINO UNO with a DIP style ATMEGA chip is you can replace the chip, while the ARDUINO UNO SMD version you cannot replace the chip.

De calidad

No hay mucho que decir de Arduino uno, de calidad y duradero. Lo único "malo" entre comillas, es que no viene con su cable para conectarlo a la computadora.
