  • Product DEV-12767 | last month

    I have one of these, and sure enough it works. Be careful when connecting it to get it the right way around! There is no obvious mark to indicate which way it connects, and the headers are symmetrical so it fits over the Teensy 3/3.1 as easily backwards as it dos the correct way. The microSD card slot should be facing the opposite way as the Teensy USB connector. This is correctly shown in the Sparkfun breadboard photo.

  • Product WRL-10004 | about 3 months ago

    rovingnetworks.com no longer exists, after acquisition by Microchip. Anyone know; does the dev kit still exist? EDIT: I see RN-ISP. http://www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=RN-ISP but not the RN-SDK-G2 mentioned in http://www.microchip.com/stellent/groups/sitecomm_sg/documents/devicedoc/jp557986.pdf (which mentions GCC and Gaisler LEON BCC toolchain).

  • Product GPS-11058 | about 3 months ago

    Just FWIW, Skytrak is putting out a new GPS module with Venus 822 chipset, check out NavSpark on indeigogo. Not clear if it will reach its funding goal though. EDIT: looks like it will happen. Maybe SparkFun can carry this one too.

  • Product DEV-11780 | about a year ago

    This is a very nice board, I have two of them (although not obtained via SF). It is as easy to use as the less-powerful ATmega-based Arduino boards, and super small as well. If you’re buying one of these, you should probably check out the support forum on PJRC, it is active and questions are addressed quickly.

  • News - Playing Doom on the Raspb… | about 2 years ago

    I really like my R-Pi, I ordered a second one but that may be months off yet. Meanwhile I got an “Olinuxino-Micro” (ARMv5, 64 MB, SD card, 1 USB) which is like a cheaper, less-capable Pi, but has many more I/O pins, and it is actually available for sale now. The O-Micro software is still very much a work-in-progress though (OE-Debian and Arch-Linux builds exist, but eg. no USB-WiFi adapter support yet). And Olimex has many distributors, SparkFun might even carry it, if they don’t mind the software-sinkhole :-)

  • Product TOL-10214 | about 2 years ago

    By the way, my sample of this device cannot provide 500 mA at 5 V as the label indicates. With a 10 ohm load (500 mA / 5V) the voltage droops to about 2.5 V with large oscillations.

  • Product PRT-08877 | about 3 years ago

    I second the request from anderson12 for a rectangular version at 0.5mm pitch. Something like the OM-TSOP-2 from Saelig.com would be great if it was smaller & cheaper.

  • News - Copenhagen Suborbital | about 3 years ago

    The CS website had a lot of photos yesterday, which seem to have disappeared. Flight trajectory was different than planned- parachutes intended to open at a lower speed, but the rocket was already nearly horizontal (?) due to guidance malfunction, before the engines cutoff (by remote command, due to range safety). “The parachutes apparently failed due to the high speed when they were deployed.” See also hobbyspace.com: http://www.hobbyspace.com/nucleus/index.php?itemid=29941 and space.com,

  • Product SEN-10656 | about 3 years ago

    Looking at the image of the underside of the part with the solder balls, the balls appear to be resting on a miniature green PCB-like substrate with copper (?) traces that actually wrap around the chamfered edge of the board to reach the other side. Anyone know if (1) that is the case and if so (2) how do they manufacture that?

  • Tutorial - ADXL345 Quickstart Guide | about 3 years ago

    Your “basic Arduino code” at http://sparkfun.com/tutorial/ADXL/ADXL345_Basic.pde
    has a bug.
    You want the values[] array to be of type UNSIGNED CHAR, meaning you must change two declarations as below:
    unsigned char values[10];
    void readRegister(char registerAddress, int numBytes, unsigned char * values){
    otherwise, you are getting the low-order 8 bits interpreted as a signed char (byte) (incorrect) as well as the high-order bits (which are in fact signed). Combining those two gives you garbage whenever the low byte value is greater than 127.

No public wish lists :(
