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.

This Arduino touch sensor module based on the dedicated TTP223 touch sensor IC. The TTP223 capacitive touch switch provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm. An on-board LED will give a visual indication of when the sensor is triggered. When triggered the module's output will switch from its idle low state to high (default operation). Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle output.
