FS1000A and XY-MK-5V 433MHz RF modules

Those modules are as simple as possible. They do not offer anything like error correction, RSSI, frequency hopping, or even two-directional transmission. They offer only basic functionality: receiver reports digital ONE when the transmitter detects ONE on the input (if in range, of course). Everything above that has to be done in the software.

Of course, there are at least a couple of libraries for different microcontrollers (Arduino and similar) like VirtualWire or RadioHead. But well, their functionality is still limited.

FS1000A
The transmitter. Smaller of the pair.

Connectors: Vcc (power), GND (ground) and ATAD (DATA, device transmits when the HIGH state is applied)
Working voltage: 3-12V. Higher voltage = more power = more range
Current while transmitting: 28mA
Range: “up to 200m”. I will check that later
Data speed: up to 10Kbps, but range drops considerably with speed above 2400bps
Sold without an antenna. No antenna = limited range. To make an antenna, just solder 165mm of copper wire to the ANT pad
XY-MK-5V
The receiver. The bigger one.

Connectors: GND, 2x DATA, Vcc
Voltage: 5V. Very sensitive to voltage fluctuations. Always use stabilized power source and decoupling capacitor
Current while standby: 4mA

Weight 40 g
Dimensions 260 × 160 × 20 mm
