==Overview==
[[File:MAX485 chip.jpg|thumb|400px|right]]
On-board MAX485 chip is a low-power and slew-rate-limited transceiver used for RS-485 communication. It works at a 
single +5V power supply and the rated current is 300 μA. Adopting half-duplex communication to implement the function 
of converting TTL level into RS-485 level, it can achieve a maximum transmission rate of 2.5Mbps. MAX485 transceiver 
draws supply current of between 120μA and 500μA under the unloaded or fully loaded conditions when the driver is 
disabled. The driver is limited for short-circuit current and the driver outputs can be placed at a high impedance state 
through the thermal shutdown circuit. The receiver input has a fail-safe feature that guarantees logic high output if the 
input is open circuit. In addition, it has a strong anti-interference performance.
