  • What is the current firmware version on these modules? It would be nice if you showed this in the description so we know what we are getting as the firmware cannot be upgraded. The last few i bought (only a few months ago) had firmware version 6.03 whereas the latest firmware is 6.15. The previous release to 6.15 was version 6.11 and this was in 2011. There are features missing in the 6.03 release.

  • Isn't it really abount time these kits can with 2x 10 way header 7x 8 way header 1x 6 way header That way there would be no need to cut up the supplied 11x 8 way headers to make up the board

  • Fran. You work so hard you've melted your keyboard ;-). Keep innovating guys, we love your products.

  • If you want to upgrade the firmware on this board with the latest version, you don't have to go through the hassle of installing a custom version of Arduino as suggested. The compiled hex file is included in the download. There is a great little program called XLoader (http://xloader.russemotto.com/) which you can use to download the firmware into the openlog. (No avrdude knowledge required)

  • The two rows of pins are spaced 0.3 inch apart so they can also be plugged into a 10-pin DIL IC socket.

  • With regard to people who have found the voltage regulators getting very hot on these boards, i have tested this out on one of our boards using a bench top power supply.
    At 5V, the board consumes approx 180mA when not doing anything, but doesn't get hot.
    When the voltage is increased to 9V the regulators get warm, but acceptable, they are not hot. Power consumption is about 200mA.
    If the voltage is increased to 12V, the regulators get hot quite quickly although current stays at about 200mA.
    It would seem the regulators are not up to the task at 12V. The board should really be supplied with 7-9V DC and not 12V

  • For those of you having problems with these running hot and drawing excess current, it seems to be because you are trying to drive them beyond the mechanical end stops.
    If you are driving these servos using the Arduino Servo library (or your own microcontroller code), then the high value of 180 (Arduino), which creates a 2.4ms pulse width, may be too high and tries to drive the servo past its mechanical end stop. This leads to a high current being drawn (1A+) and the servo gets hot.
    If you reduce the Arduino Sketch value from 180 down to 170 (or drop your pulse width down to 2.3ms max) then you should be ok.
    In normal operation (no load), these servos only need about 50mA when moving and virtually nothing when stationary.
    It seems that the setting of the mechanical end stop varies somewhat.

  • At hobbytronics, we have written an Arduino sketch for this board. It outputs the Gyro X, Y and Z as well as the Accelerometer X, Y and Z.
    You can find it here http://www.hobbytronics.co.uk/arduino-adxl345-imu3000

  • Check this link
    It is an Arduino library to read the values for this sensor based on a similar Pololu board. Haven't tried it out but it claims to have a function for computing the tilt-compensated heading for those looking to use this sensor as a tilt-compensated compass.

No public wish lists :(
