POWER SUPPLY AND PROTOTYPING AREA
The controller board contains an ASK radio receiver module. The pinout corresponds
to the standard PICtail™ connector. Thus, it may be easily replaced with similar models
accommodating other frequencies, modulation methods (ASK vs. FSK) as well as
adapting transponder boards for two-way communication.
On the controller board there is a jumper (J5) that allows for receiver card selection.
The K
FSK transceiver card is available. The jumper configuration is:
• ASK receiver board: pins 1 and 2 connected, jumper to the left side
• FSK board: pins 2 and 3 connected, jumper to the right side.
• J5 also allows the radio receiver output to be disconnected from the main
The board features two connectors. One 14 pin is dedicated for the receiver modules.
While the connector has 14 pins, not all the pins are used. The ASK receiver board only
uses the following pins:
• Pin 11 – RF data out
• Pin 13 – V
• Pin 14 – GND
The board also features a 28-pin connector that provides an easy access to all of the
PIC16F886 pins.
A 2-line by 16 characters LCD display is present on the board. It is used to display.
When the controller receives a K
data will be shown on the display. The LCD contrast can be adjusted by the contrast
pot located on the bottom side of the controller board, near push button PB1.
The main processor contains a SOIC PIC16F886 operating at 8 MHz. The
microcontroller provides connections for the LCD display, programming, push buttons,
LEDs and RF board control. Please refer to the schematic in Appendix A. “KeeLoq®
3 Development Kit Schematics” for further information.
The power supply circuit is designed to regulate a maximum current of 100 mA at 5V
from an external 9V power supply.
The prototyping area includes convenient V
custom circuitry. The user must ensure that the Prototype area custom circuit current
draw added to the controller board consumption does not exceed the 100 mA total limit.

injecting an encoder’s digital output directly into the decoder.
