Now there are counterfeit NRF24L01+, what else ?

The very cheap (< 1 dollar) NRF24L01+ seems to be counterfeit : http://hackaday.com/2015/02/23/nordic-nrf24l01-real-vs-fake/
They seem to be working the same, but I would like to see someone measuring them with a professional frequency analyzer.

When FTDI bricked the counterfeit chips, I had one of them.

I do have Arduino clones that have printed “Arduino” on them. They are counterfeit, but at least they have a real working ATmel chip, or could there be working ATmel chips now that are fake ?

I have a very cheap DS3231, that turns out to be not within the specifications. It could be a factory pre-run.

I also have those very cheap NRF24L01+, and the printed label on them look like the counterfeit ones.

So now I don’t trust any component I bought on Ebay. I have very cheap DS18B20 temperature sensors with labels that are not printed in the middle. I also have very cheap ACS712 current sensors. Are they the real thing or not ?
When I look in the mirror, is that … ?
What else is counterfeit ?

"What else is counterfeit."

Don't buy that Louis Vitton bag for $10 at the local pub car park. Change the spelling a little and no one notices.

Dude in a white van tried to sell me a genuine Alpine stereo. I wonder if that was counterfeit? (Or stolen?)

The van was stacked to the ceiling with everything imaginable including an "indestructible salad bowl" he kept smacking into the steel bumper to prove it really was "indestructible". Strange days.

:grinning:

Anything is possible. Some of the supposedly brand new vehicle electronics had clearly been removed using a machete.

What I don't understand is why would the counterfeiters charge a lower price? That is just plain stupid.

[/quote] Normally the counterfeit goods cannot make it into legitimate supply chains so they have to sell them on places like ebay (or from the back of a van) so a reduced price makes them competitive and more likely to sell than the legit one for sale. If they sold them for the going price then they will have less sales as some people will be (unknowingly) buying genuine items from genuine suppliers.

True, but Sparkfun sells the MPU-6050 module board for 39.95 dollars : https://www.sparkfun.com/products/11028 The MPU-6050 (plus extra voltage regulator) is 2.02 dollars on Ebay : http://www.ebay.com/sch/i.html?_sacat=0&_sop=15&_nkw=mpu6050&rt=nc&LH_BIN=1 Farnell/newark sells the MPU-6050 chip itself for more than 10 dollars : http://www.newark.com/invensense/mpu-6050/gyroscope-accelerometer-mems-3axis/dp/37T8113

That difference is just too much, and I think the MPU-6050 on Ebay is the real chip, is it ?

There are more examples, the cheapest Pro Mini I bought on Ebay was 1.70 euros, and that was inclusive shipping.
