nRF24LU1 board is alive and well

So I swear I'm not dead. I have been working hard on writing code for the 24LU1 board. I have a lot of software working now, and I just wanted to post a video of this guy in action. The only problems I've found with the board are that the /RST LED was supposed to be wired in active low configuration, but I ended up doing it like all the other LEDs (it's on all the time *except* when you push the reset button).



Edit: I now have nRF24LU1 breakout boards for sale at http://store.diyembedded.com!

i'm glad you still alive.... anyway what do you think about micrel rf transceiver...is it better than nRF24LU1?

Overall, it appears the only advantage to the Micrel chip (MICRF001) is lower parts count. It doesn't require you to add a matching network (like all the Nordic RF chips do), but it has a considerably slower data rate (4.8 kbps compared to the nRF24L01/nRF24LU1's 2 Mbps). This part doesn't compete with the 24LU1, as it doesn't have a microcontroller onboard. IMHO, the 24L01, which it would compete with somewhat, can kill it on just about any application.

thanks for the answer, how about the current consumption betweeen micrel and nordic ?

It appears the Micrel part has a lower operating current, but it also doesn't have a low-power shut down mode like the 24L01 does, so as long as you're not transmitting/receiving all the time, you my still be able to have lower average current consumption with the 24L01. And the fact that since the 24L01 transmits data so much faster, you are in a high-current drawing mode for a much shorter time, which also brings average current consumption down.

I have also made a LU1 Module and Lu1 small Doggle, 0402 is OK for solde just need some careful.

have you tried to develop the LU1 for isochronous? the hal_usb doesnt support one.

Brennen, thanks for your great work with the Nordic chips and your prolific postings. I have read many of them over the past year and found them extremely helpful.
