Description
RS485 click 3.3V carries the SN65HVD12 half-duplex, RS-485 transceiver from Texas Instruments. It is designed for balanced data transmission and complies with EIA standards RS-485 and RS-422. The click is designed to run on a 3.3V power supply. RS485 5V click communicates with the target microcontroller over UART interface, with additional functionality provided by the PWM pin on the mikroBUS™ line.
Internal ESD protection circuits protect the transceiver bus terminals against ±16-kV Human Body Model (HBM) electrostatic discharges and ±4-kV electrical fast transients (EFT).
The SN65HVD1x half-duplex family provides internal biasing of the receiver input thresholds for open-circuit, bus-idle, or short-circuit failsafe conditions, and a typical receiver hysteresis of 35 mV
There are four screw terminals on the board Those marked with “+” and “-” are RS485 differential high and differential low communication lines. We added two more terminals for VCC and GND reference if needed for further interfacing. Communication with the board is done using simple UART interface.
Type | RS485 |
Applications | Board is suitable for Low power RS-485 systems, DTE/DCE interface Packet switching, Local area networks (LNAs), Data concentration, Data multiplexers, Integrated services digital network (ISDN) and more |
On-board modules | SN65HVD12 differential line transceiver |
Key Features | On-board Bias and Termination resistors with related jumpers. Simple UART communication interface |
Key Benefits | Meets or Exceeds the Requirements of ANSI TIA/EIA-485-A |
Interface | GPIO,UART |
Input Voltage | 3.3V |
Compatibility | mikroBUS |
Click board size | M (42.9 x 25.4 mm) |
