You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has a fixed I2C address...
Going from TTL to RS485 is made simple by this prototyping friendly module. On one side of the board are the TTL IOs, and on the other are the RS485. At the core is a MAX485 which is powered by 5V.
USB to TTL converters are an essential for prototyping - they provide a direct interface with the target device. This module connects to your computer USB port and there are 4 wires which connect with your target device. This model is the bare version of our enclosed model.
This USB to TTL converter combine the USB-232-1 (USB to Single RS232 Adapter) and TTL-232-1 (Port-powered RS232/TTL converter) allows you to convert USB to TTL/CMOS compatible levels and vice versa.
