I can't make it start in boot mode even thou boot jumper is set correctly. OTA Update server from wiznet seems to be not working any more. Is there actually a way to update the firmware of this shield?

Pins VR1 and VR2 come preset. Please DON'T change the default configuration. And the dust sensor don't need any calibration.

My base shield was working fine, but when I connect this WiFi Fi250 appears the following error message:"avrdude: stk500_getsync(): not in sync: resp=0x00". When I remove the Fi250 WiFi shield, the error message disapears! Whats could be?

The unit of Detectable range of concentration is pcs/liter. And it is a qualitative test, so you may not transfer it to the concentration in ug/m3.

Hi, this product seems really sweet. Are there any limitations in using Stalker with both base and wifi shields stacked up on top each other? Wont their pin requirements conflict in this scenario?

yes, you can use them together. But please pay attention to the 'USB5V' port, it could provide 5v only if you plug a external power to the stalker, such as UartSBee.
