1. Your actual current capacity will vary based on the type of load, the length and size of wires, power supply
capability and other factors.
2. Using the Wasp
Figure 2 shows the Wasp unit with its available connections.
Figure 2. Wasp connections
To use the Wasp, connect the RC connector to an RC signal source such as an RC receiver
or to a microcontroller unit programmed to generate servo pulses. The polarity of the
connector is shown. Generally the black/brown wire of the RC cable is oriented toward the
outside edge of the RC receiver when plugged in. Reversing the RC connection will not
damage the unit.
Connect a battery of between 6V and 28V to the battery. Up to 100% of the battery voltage
will be applied to the load. The Wasp contains an internal voltage regulator (BEC) to power
itself along with the receiver and normally does not need a receiver battery attached. Direct
solder connections of 14AWG or smaller wire are supported. An optional screw terminal block
may be soldered to either side of the PCB for easy connection of the battery and motor wires.
Polarized connectors are recommended for the battery connection to avoid reversing the
battery polarity and possibly damaging the Wasp.
A switch is recommended between the battery positive and the Wasp. The Wasp draws a
small amount of current even when the motor is not running and if left connected will drain the
battery. Auto parts stores often carry switches of appropriate current rating for the Wasp.
The motor outputs will vary between 0V and battery voltage in either polarity to provide
reversible control of the motor. Connect the wires to the motor or other load using solder
connections or the screw terminal block if installed.
To control the Wasp the RC signal is varied between neutral (off) and full forward and full
reverse at maximum stick travel. The motor LED will show this activity. The status LED will
