    Perhaps it should be noted that the X and Y axis orientation of the devices are not correct; i.e., use the x axis of the accelerometer as the y axis reading, and vice versa. Additionally, the fusion board has a 5v to 3.3v regulator, but no I2C level conversion…hmmm. Perhaps add a couple MOSFETS to do this and make the board a complete 5v unit, else get rid of the superfluous 3.3v reg, and run the board as strictly 3.3v.

    The ADXL345 still outputs two bytes. It only has a resolution of 10 bits; i.e., only the lower 10 bits are used.

    Hey thanks! I guess I missed that. I didn’t look at the back of the board.

    Support for CTS should be added. The Tx RF buffer on the XBee is only 17 bytes. It can easily be overflowed. By adding CTS, fully interrupt driven transmit can be used.

    Too bad you folks didn’t use GSM/GPRS modules made by Sony and Wavecom(sold by Multitech). Sony’s GR48/64 and Wavecom’s Socket Modem [http://www.multitech.com/en_US/DOCUMENTS/Tutorials/primers/universal_socket.aspx (model MTSMC-G-F4)]. These both have an embedded TCP/IP stack, so once a GPRS connection is made it’s like a serial port to the other end. i.e., no TCP socket software programming required. I have extensive exp with both of these (> 10 yrs), and they are quite reliable. With the SM5100, you’ll need TCP/IP in the Arduino.
    Australia is 900/1800mhz; same as UK/Europe.

    Please send me an email when this is available on breakout. Thanks.

    I have this sensor and have worked with it using the Atmel CPUs. The analog output is unstable. I had to use the PWM output; much more reliable.

    Oops! There is a 10k on the input. Additionally, jumper C5 and C6 to work woth DC.

  • Product BOB-08704 | about 4 years ago

    Jumper that input cap so it will work with DC; maybe a solder pad jumper. I’d like to see a neg voltage on the op-amp so it could be used for null or used for offsetting the input. Maybe a current limiting res on the input too. Thanks.

    Additionally, the Eagle files will not unzip…

No public wish lists :(
