    the schematics show pins 1, 2, and 48 of the vs1053b (mic-left/right inputs) not connected. visual inspection of the lilypad confirms. * is there any mechanical way to tap into these pins?
    * i see there are testing points on the amplifier inputs … could i bring the rn52 in through these and carefully manage to turn off mp3 decoding when there is rn52 activity? would these two signal paths entering in parallel into the amp create problems? * i’ve built a very nice “background sounds” sculpture system that simulates the forest (lilypad mp3, 2000mwh lipo, light sensor, surface transducer, bird recordings, mounted in wooden “bricks”). These would be an ideal hands free platform that i would like to add the rn52 and be able to mediate between self generated background (lilypad’s mp3) and the 2/way hfp or a2dp streaming received by the rn52 from iphone. any suggestions on how to get these two to work together?

    is there any way to turn off all the LEDs on this board? its not so much about power consumption (though i imagine they do consume a measurable amount) its more about LIGHT - i am using this on a breath sensor used in sleep apnea studies and this thing generates so much light that I have had to cover each LED with blu-tack but its hardly professional looking.

    is it possible to connect this to the lilypad mp3? then i could toggle between a2dp/hfp and onboard mp3s. or maybe even stream the other protocols over bt and let the lilypad decode them?

    is it possible to connect this to a lilypad mp3 to use it’s amplifiers and toggle back and forth between the a2dp/hfp as a sound source and the lilypad’s onboard mp3s?

    is it possible to connect this to the rn52 breakout ?

    we used it in our “conscious clothing” project (see video: http://www.youtube.com/watch?v=XPvyIXdkc4g), we calibrated it with a $5100 Thermo Scientific 1500, and within it’s range of sensitivity found it to correlate remarkably well. we’ve yet to do serious “in the oven” controlled experiments but hopefully will be doing so soon. it reacts much quicker than the 1500, but that is because the 1500 has a vortex filter so you can select the particle size. it makes false readings when jolted, but with an accelerometer we can filter that out.

    I have this working with a Lilypad and rn41xv hosted on the card – but only if I use pin 0/1 (rx,tx) of the Lilypad – I have not been able to communicate with the rn41xv using the softwareserial library at any combination of baud rate or various pins. Has anyone out there been able to get this to work with softwareserial on the Lilypad? … btw, i have also managed to switch the rn41xv it to HID profile and can pair with my iDevices as a keyboard to log data or drive simple ios apps like magic monitor. IT WOULD BE VERY HELPFUL to be able to move it off the rx/tx pins to facilitate programming and debugging … .
