spirilis 1,265 Posted November 17, 2012 Author Share Posted November 17, 2012 Thought I'd attached gerbers for this to the thread, looks like I didn't... Here they are: Seeed gerbers: Seeed_43oh_nRF24_5x5.zip OSHpark.com gerbers: OSH_43oh_nRF24.zip Parts/BOM: nRF24_IRQ LED - SMD LED, 0603/0805/1206 should work SPI_I/O LED - SMD LED, 0603/0805/1206 should work R1 - 10K SMD resistor, 0603/0805/1206 should work R2 - 1K SMD resistor, 0603/0805/1206 should work R3 - 1K SMD resistor, 0603/0805/1206 should work R4 - 10K SMD resistor, 0603/0805/1206 should work Q1 - PNP BJT transistor, SMD, SOT-23, example: http://www.mouser.com/Search/ProductDetail.aspx?R=PMBS3906,215virtualkey66800000virtualkey771-PMBS3906215 Q2 - NPN BJT transistor, SMD, SOT-23, example: http://www.mouser.com/Search/ProductDetail.aspx?R=PMBS3904,235virtualkey66800000virtualkey771-PMBS3904235 Quote Link to post Share on other sites
spirilis 1,265 Posted November 20, 2012 Author Share Posted November 20, 2012 Reposting this from the GB-8 thread: PS- When I get the boards (should be soon), I am going to populate the Q1/Q2 transistors for the LEDs so folks don't have to mess with ordering those. Not changing the price of the boards at all (the transistors cost all of 5 cents a piece anyway), and that way folks only need to supply SMD resistors and LEDs to get the SPI and nRF IRQ status LEDs working. So ignore Q1 and Q2 from the BOM. Quote Link to post Share on other sites
spirilis 1,265 Posted November 21, 2012 Author Share Posted November 21, 2012 Woohoo got my boards today! I'll solder one up tonight and see how it is. cubeberg and bluehash 2 Quote Link to post Share on other sites
bluehash 1,581 Posted November 21, 2012 Share Posted November 21, 2012 Man.. these look good! Just in time for Thanksgiving. Quote Link to post Share on other sites
spirilis 1,265 Posted November 21, 2012 Author Share Posted November 21, 2012 PS- Hadn't realized what HASL surface treatment was until now (solder coating). There's just enough solder on these pads that I needn't add any of my own, I'm just dabbing a tiny amount of flux on each one and the transistors are going on quick. Very nice.

spirilis 1,265 Posted November 22, 2012 Author Share Posted November 22, 2012 Two finished boards (which I'll keep)- That's a Stellaris LaunchPad btw. Fits great over the MSP430 launchpad too of course. Note the 0603 resistors for the LED circuit ... looks tiny against those pads, but no extra solder required b/c of the HASL coating either. The rest of the boards with PNP & NPN transistors soldered on- Next task: Qtip+alcohol, clean flux off all the boards. After that, test my newly soldered boards... abecedarian 1 Quote Link to post Share on other sites
spirilis 1,265 Posted November 22, 2012 Author Share Posted November 22, 2012 Boards work: The LP on the right is a v1.5 with a G2553 transmitting a command every 500ms or so, the LP on the left is a v1.4 LP with a G2533 (and custom gender benders I had OSHpark make a while back, since I'd soldered female headers on my old LP) blinking its LED upon receipt of every packet. Red LED blinking perfectly. Status LEDs on the boosterpacks work correctly too; the SPI I/O in this example is barely a flicker, and the nRF IRQ briefly flashes in unison with that. If there was a bug in the firmware and it wasn't answering nRF24 IRQs correctly, the LED would go on hard so you'd see it. Should be handy for troubleshooting. bluehash and JonnyBoats 2 Quote Link to post Share on other sites

JonnyBoats 40 Posted November 23, 2012 Share Posted November 23, 2012 WOW! these definately look interesting. Are you still planning on a group buy? Quote Link to post Share on other sites

hova 7 Posted November 25, 2012 Share Posted November 25, 2012 Is this just for data , or could this handle motor pwm? Basically I have some r/c drift cars and a crawler that needs a radio , but I dont like using off-shelf parts. I would be lookin at two inputs (linear trimmers) , and maybe a couple on/off led drivers. The reciever would have a drive motor , a steering servo(or motor) , and maybe some led drivers as well... Sorry for such a specific/generic question , but I have a million ideas , and this would put one hobby to rest. -hov Quote Link to post Share on other sites
spirilis 1,265 Posted November 25, 2012 Author Share Posted November 25, 2012 Nah it's just for data. Need an MCU on both ends. Sent from my C3PO via Tapatalk Quote Link to post Share on other sites
jrychter 14 Posted November 26, 2012 Share Posted November 26, 2012 Hey, thanks for posting the Gerbers. They should be fine for folks ordering from iteadstudio.com as well (they use the same pcb house as seeed does). This is great work! Quote Link to post Share on other sites
abecedarian 330 Posted January 8, 2013 Share Posted January 8, 2013 I just want to say that I am liking this. Placing the nRF24L01+ booster beneath the Stellaris doesn't increase the height as much or obscure the LP's buttons like it does on top. MSP430LP on the bottom, nRF24L01+ in the middle and Stellaris LP on top: Stackable headers should've been the standard on the MSP430 LP. *note- please ignore the extra headers soldered to the Stellaris. I have some other ideas mulling around and those may make it easier for me when I actually know what I'm doing. ;-) and the glasses in the background are +2.0 reading glasses. bluehash 1 Quote Link to post Share on other sites
