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.

Why use RS485 managed by the MAX485? There is a lot on offer so let’s just look at the highlights:

• Operate from a Single 5V Supply
• Allows up to 32 Transceivers on the Bus
• Data rate: 2.5 Mbps
• Current-Limiting and Thermal Shutdown for Driver Overload Protection
• MAX485 Datasheet

As a whole, this module as a whole brings the above features and the following functionality:

• Breadboard friendly design (standard 0.1" spacing)
• Easily identifiable connectors
• An optional terminal block for the TTL IOs
• Fully assembled, ready for use
