View Full Version : Weight of Zig 100 for wireless bat data logging

Hello, need to know the weight (to the 0.1 gram) of the Zig 100 wireless UART. It's for a rather unusual research project involving collecting accelerometer data from bats in flight. Development time is short and so far the Zig-100 boards look to offer the best combination of ease of use (practically plug and play with CHR-6d 6 axis accelerometer's UART interface) and small size, but I need to know the weight since the little guys can only haul an extra 5 grams tops. I've only been considering solutions for a couple days so if anyone has any other ideas...

Can't help with the Zig 100, but an Xbee module weighs about 4g. My scale doesn't weigh low enough..

Ay, and the standard xbee's are 3g, just wish the zig 100 datasheet published weight too, they've got every other spec in there... I bet desoldering the header pins on a zigbee might save .5 g and with a .8g 20mah lipo, 1.5g CHR-6d IMU, plus wiring/freeformed voltage regulator would put the total system a little over 5g.

Hey Zach_G,

You're in luck. I happen to have Zig-100's laying around and a scale that does 0.1g.

I've got them in at 3.2g.

Fantastic, thanks so much! Little denser than expected but probably still a good investment for other projects needing simple wireless communications.
