Mounting Bracket Holder Stand is specifically designed for the HC-SR04 Ultrasonic Sensor Module. With this ultrasonic sensor you can attach the le to your application such as small robots or DIY projects very quickly and conveniently. This best mount bracket is made from good quality Acrylic. This mounting holder has mounting holes of a diameter of 3.8mm. Use this Arduino distance measuring sensor to easily attach your ultrasonic distance sensor to your robots, onto a servo for panning, and anywhere else you’d like. 90 degree mounting with 3 screw holes at the base and 4 screw holes for the ultrasonic sensor itself.

MAX485 RS485 TTL To RS-485 MAX485CSA Transceiver Module is based on the Maxim MAX485 IC to allow serial communication over very long cable runs (up 4000 feet / 1200 meters). MAX485 converter board, serial data can be transmitted in both directions (half-duplex) at a data rate up to 2.5Mbps. The max485 TTL to rs485 converter module operates from a standard 5V power supply and uses 5V logic levels allowing them to be interfaced to the hardware serial ports of microcontrollers such as Arduino/PIC etc. The direction of communication can be controlled with just one digital pin (see diagram). RS485 to TTL module is also possible to connect multiple modules together for communication between 2 or more devices. For even greater distances two modules can be configured as a repeater.
