LED 0 – programmable LED
•
A green indicator LED is connected to the microcontroller. It is totally programmable by the user from the program code. In
addition, the LED 0 indicates when Waspmote resets, blinking each time a reset on the board is carried out.
• LED 1 – programmable LED
A red indicator LED is connected to the microcontroller. It is totally programmable by the user from the program code.
USB Power LED indicator
•
A green LED which indicates when Waspmote is connected to a compatible USB port either for battery charging or
programming. When the LED is on it indicates that the USB cable is connected correctly, when the USB cable is removed
the LED will switch off automatically.
