These little Seeeduinos have mass of only 3.047 grams with header pins, less than copper pennies minted before 1982. We hard-wire the gyro package and stack a coupla watch batteries, we will still come in at less than 10 grams. The micro SD interface might be a bit more tricky, but we are still not busted: the Seeeduino has 256k onboard memory which might be enough for a short flight. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If this approach works, then we hardwire the SD card without the interface structure.
