You probably heard about Mikroe shopping-warehouse in order to get a good price for development components. I have been working with them during last few years, but only recently decided to write an article about it.
My best experience was while ordering by Jumper wires pack... I think, they are the best company on market which provides such type of jumper cables . To be honest, I wasn't really sure if this store is trustworthy or not, since all online shops nonsense from time to time..... But no! My experience went well and I am ready to tell you a little bit more :-)
I ordered a bunch of things there: ATtiny2313 , UM1033D etc.... All standard stuff Arduino projects. Ready in 10 days as stated on website, which was ok for me. I have been working with other online shops before and the delivery time was a lot longer... For example: I placed one order in Conrad Online Shop 3 months ago, but still don't have it. They say that "it will arrive soon"... Yeah right!
Also I placed an order from Farnell , 3 month ago as well, because they have a good price for Bluetooth modules HC-06 . However, the shipment arrived only last week....
I could place here a list of all shops where you can find these components locally or globally..... however it's not worth to do so. Very often you will find these stuff in your local electronic shop around the corner... Let's return to Mikroe shopping-warehouse.
I have been experienced with other shops as well, to be honest... But I would like to mention two shops which deserve a special attention. Let me explain why; To start with AliExpress (or Aliexpress), they are selling almost everything under the sun & moon! And it makes sense that Arduino components are available on their website :)))
Let's see the price for one Arduino Pro Mini board for example:
$2.23 on Aliexpress $4.29 on Mikroe
Yeah, that's why I love this shop so much... They also offer special deals and discounts from time to time... For example: 1pcs 5V Arduino Nano V3.0 can be bought for less than ONE dollar!
I don't know what will happen if you try to order more than one item.. The shipment might me huge or maybe not..... I tried once with a pair of LM35 temperature sensors from China, but it turned out that they shipped items according to the weight.... Which was 200 grams total weight :) ... And guess how much it cost? I paid twice as much as I would pay for a single order....
