Description
*** Discontinued, no longer available ***
This kit includes a 4-channel key fob transmitter, a YK04 315 MHz PT2272-based remote control receiver module, and receiver breakout board.
Ideal for general purpose short range remote control applications, such as roof-top remote control of your rotator system during maintenance and calibration work, and will easily connect to a K3NG based rotator controller.
Provides five momentary buffered open collector outputs to ground;
• button A (eg: CW)
• button B (eg: CCW)
• button C (eg: Up)
• button D (eg: Down)
• Valid Transmission
Features:
• PCB: 5cm x 5cm
• Mounting: 4 x M3 hole
• 5V operation
• LEDs indicate output state (VT, A, B, C, D)
• LEDs enable/disable jumper
• Provision for SMA launcher connector as external antenna connector
• Momentary (non-latching) outputs via 74ACT05 to ground
• Open drain outputs
• Range typically 10-20m (garage door opener)
The supplied receiver module has a PT-2272-M4 receiver (momentary version) so buffered outputs remain LOW (switched to ground) whilst the associated button is depressed.
Receiver module outputs are active HIGH and pass through a 74ACT05 open-drain buffer.
This provides Logic LOW with signal and high impedance with no signal.
External Antenna Provision
A length of hook up wire can be used as a basic antenna, but an SMA launcher and a short length of RG-316 is supplied if you wish to connect something better.
