IMPORTANT: Read ALL the operating instructions before using Wasp.
Powering Wasp

mains or from a standard AC-DC converter. On the board there is a battery charge monitor.
This configuration makes possible to use different means to recharge the battery supplied
with the mote. The single-cell Li-Ion battery can be charged from the USB, a solar
cell, and potentially AC adapter sources (we do NOT support this last configuration, though).
The circuitry allows battery-to-input power switchover, so the system can be powered
The circuitry allows battery-to-input power switchover, so the system can be powered
directly from the power source (USB in this case) rather than from the battery. The voltage
at the input of the circuit can be as low as 3.7V and should never be over 6.5V.

Other features include an indicating charging led when the battery is being charged.
Battery charge can also be monitored from the WASP through a resistor bridge connection.
Power from battery
To test the board:
To test the board:
1º- We are going to choose its working mode connecting the device through the USB. (see

2º- Once the mode is set and saved, we can disconnect the device from the USB and power
it using the battery.

For making the different tests in WASP we'll use the USB communication feature, we'll set
the test we want sending a character from a computer to WASP via USB.
