Communications Modules

XL1276-D01 wireless module is SEMTECH’s latest LoRaTM modulation technology wireless chip, the module in addition to the traditional GFSK modulation technology, but also uses the LoRa (remote) spread spectrum technology, with ultra-long distance spread spectrum communication, high anti-interference And minimizes current consumption. Using LoRaTM mode can achieve high -148dbm high

Description: PCB size:1.52*2.22cm work voltage:5V Output: output high level when receiving laser signal; output low level when not receiving a laser signal. NOTE: The sensor uses a non-modulated laser receiver, please use indoors where no light, sunlight or other fixtures may interfere, recommended for use in dark environments. Package Included:

1.On-board MAX485 chip, A low power consumption for RS-485 communication, slew-rate limited transceiver. 2. Onboard then 5.08 (mm) pitch 2P terminal to facilitate RS-485 communication wiring. 3. All pins of the chip have been lead so it can be controlled through the microcontroller. 4. Working voltage: 5V. 5. Board size:

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).
