KRS418 RECEIVER KIT $35.00  

25.4mm  X  35.56mm

30.48mm  X  43.18mm
1.0"  X   1.4" 1.2"  X   1.7"

The KTS418 and KRS418 kits are designed to use a minimum of components to simplify construction and to reduce size and cost. These basic kits include the components needed to build a functioning wireless remote control system with only the addition of power sources and some wires.

The kits do not include a battery connector, wall transformer, antenna or enclosure.

Kits include a high quality FR4 epoxy glass, etched and drilled PC board with legends screened on top that show where each component is to be placed.  The wireless RF units are already soldered in place on the PC boards. All other parts are through-hole and must be placed and soldered by the kit builder. The boards have a solder mask on the bottom side that covers all  interconnecting metal to help prevent solder shorts. Space is provided for the addition of optional terminal blocks for ease of making and changing connections. Optional parts are available from electronic parts distributors.

Four control bits can be sent individually or simultaneously by pulling transmitter inputs lowOutputs can both source and sink 25 milliamperes each to drive  loads.  A light emitting diode on the receiver board indicates when valid data is being received.

The kits uses RF transmitter and  receiver circuits that operate at 418 MHz with a range of up to 1000 feet. Thanks to these new modules  the problems associated with building your own transmitter and receiver such as tuning by adjusting capacitors and inductors are things of the past. After assembling the kit you simply apply power to the transmitter  and attach a 6.7 inch antenna to send data. The same is done for the receiver which is a superhetrodyne having excellent stability and sensitivity. Absolutely no adjustments of any kind are required.

The transmitter can be powered by a 6 to 12 volt battery and draws 2 microamperes of standby current and only 5.5 milliamperes during transmit for long battery life.  The receiver can be powered by a battery or a 9 or 12 volt DC wall transformer.
