Guess&Giveaway #SeeedHit 6th
We got 6 comments this time, it seems it’s quite hard that the mini fishbowl mislead someone to “humidity” related sensors. What do we mean by “Picture of this week is much hard than before, so tips are hidden in this picture too“? If you download the original picture and zoom it, you will get the answer:
Yes, this is a main board integrated with LED driver, here’s the origin of this project, we always wanna have a tiny controller for LED strip that can be wearable, since Xadow mainboard has limited ports and lack the ability for big current, we developed one with external battery holder and Grove dock.
At first stage we use the old main board and design an compatible LED driver module for xadow.
This LED Strip module features a AtMega168 controller, communication with the main board via I2C, we occurred some problems in the synchronization and reset function with the main board, driven by the need for an integrated led controller, the recent design is what you see in the last guess&giveaway.
Story finished, here comes the puzzle: what’s this used for?
About Author
By the looks of it, this is a standalone wireless Sensor Node, Used for sensor or light data logging or weather monitering can also be used as environmental monitoring.
I guess WiFi based because of an external huge pcb antenna on the left (the base board is possibilly a Seeeduino Cloud + battery/Solar input) as it says “Light” I am guessing it has a Direct Solar pannel interface. The object on the right do create suspitions to as is that an on off switch or pannel protection circuit or a V/I measurement circuit !!
On top of the base board is a Groove Shield with 2 I2C sensors and an Analog Sensor(rest is hidden :P).
This also have a ~5-6W pannel by the looks of it, which should be enough to power the Seeeduino Light Board 🙂 and there must be a Li-po/Li-ion battery hidden somewhere beneath the pannel.
Well thats all my observations 🙂 😛 😛

Some feedback:
The base unit is a LinkIt ONE. (http://www.seeedstudio.com/depot/LinkIt-ONE-p-2017.html)
The antenna is the GSM one. If you look at the third pictrure, you see all the antennas. The top one is the GSM, the middle one is the 2.4 GHz wifi/bt, and the bottom one is the GPS.
I’ll throw some credit your way for panel wattage guessing and the Lipo goess. I figured it was there, but didn’t know what kind of size would be asked of it. I haven’t done load tests on the draw of the LinkIt. One day I will, as I’m hoping to put a self-contained unit on a train and have it do environmental readings. It will be powered by a single 12v, 3 watt glass panel. It would wardrive also, because why not?
Looking at the picture I know a few things:
-There’s a LinkIT ONE in there
-The cell antenna is connected
-The Grove shield is used, and there’s at least three sensors plugged in
-The battery is connected using the power switch
-The plastic housing is not waterproof
-There’s a solar panel (I mean, it’s hard to miss…)
I’d say this is a solar powered remote sensor setup that phones home over GSM. I would hope that it’s using the GPS to sync the RTC. I’m still not sure why it wouldn’t be in a water resistant case and why it would need a switch, but maybe it’s not needed all the time.
congratulation!
Thanks! I do know my LinkIt well.
This one has a link-it one with a grove shield and some sensors behind the panel.
IoT demo for the linkit one – solar power standalone live data streaming.
and what’s it used for? For World domination of course 🙂
Solar panel, Linkit one and grove shield?
