Raspberry Pi RS-485 Serial Communication Protocol Expansion Board -74961
product detail
Description:
RS-485 is a cost-effective solution in serial communication networks. It can be used up to data rates at 10 Mbit/s or distances up to 1200m at lower speeds. This RS-485 Shield is a standard add-on board for Raspberry Pi. It is integrated with simple screw terminal as well as DB9 interface.
Features:
One driver and one receiver per part
EMI noise minimization
Transmission rate up to 2.5Mbps
No driver slew rate limitation
Short-circuit current limited
Fail-Safe Applications
Compatible : Raspberry Pi 4
Applications:
Low-Power RS-485 Transceivers
Level Translators
Transceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks
Half-duplex applications
Grove I2C interface:
We reserved the I2C interface so that you can easily use it with I2C devices. It should be noted that the VCC of this port is 5V, and you need to confirm whether the module is compatible with 5V voltage.
SCL: I2C serial clock, connected to GPIO03 of Raspberry Pi. SDA: I2C serial data, connected to GPIO02 of Raspberry Pi. VCC: Connect to the 5V pin of Raspberry Pi. GND: Connect to the Raspberry Pi GND pin.
