Fail: badly designed PCB for the Wireless Multi-sensor

I sell the boards that was badly designed.

The LED is connected to Vdd through R1 which makes it light up as soon as you power the wireless sensor. It is supposed to only blink when sending data.

This can be corrected by cutting and bridging  as in the picture below.


After this has been done the board is 100% OK.
