Industrial 6-ch Relay Module for Raspberry Pi Zero, RS485/CAN, Isolated Protection (Zero 6-ch relay industrial)

Industrial 6-ch Relay Module for Raspberry Pi Zero, RS485/CAN, Isolated Protections, Tailored For Raspberry Pi Zero Series also Suitable For Raspberry Pi Zero With Pre-Soldered Pin header.


  • RS485 half-duplex communication: using SP3485, UART control, auto RX/TX switch
  • CAN half-duplex communication: using MCP2515 SN65HVD230 solution, SPI control
  • Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
  • Onboard photocoupler isolation, prevent interference from external high-voltage circuit connected to the relay
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
  • Onboard resettable fuses and protection diodes, ensuring current/voltage stable output, preventing over current/voltage, better shock-resistance performance
  • High quality relay, contact rating: ≤10A 250V AC or ≤10A 30V DC
  • ABS protection enclosure with rail-mount support, easy to install, safe to use
  • Comes with development resources and manual (wiringPi and python examples)

XBEE Shield with RS485 for Arduino UNO (XBEE RS485 Arduino UNO)

Arduino is an open-source controller board, popular among electronic enthusiasts for making interactive projects. But for those who are not familiar with electronics, adding circuits to Arduino may be tricky. That’s why keyestudio develop this XBEE sensor shield. It can help you connect most sensor modules to Arduino pretty easily. The shield extends the digital and analog interfaces into 3PIN interface. It also comes with RS485 communication and XBEE Bluetooth module interface.

You can change the communication way via the jumper cap on the shield. If all the three jumpers are connected to APC, the shield will realize the XBEE Bluetooth communication. If all jumpers are connected to 485, realize the RS485 communication function.

Onboard also comes with a reset button, a D13 indicator, and some common communication pins of 2.54mm pin pitch, such as serial port, IIC, and SPI communication pins.

Besides, it also has two 2pin terminal blocks. One is VIN GND terminal block, used to supply the external power for the UNO R3 control board, with an input voltage of DC 7-12V. The other is the Servo_PWR terminal block, used for VCC voltage input/output. If not connecting the external voltage, supply 5V for the shield; if connecting the external voltage, VCC voltage is actually the external input voltage.

Features and specifications:
  • Compatible with Arduino UNO R3.
  • Comes with 14 digital input/output pins.
  • Comes with 6 analog IO pins
  • Onboard comes with a digital port power terminal block
  • Comes with an external power input terminal block and a input contact pin ( power on the control board with DC 7-12V)
  • Comes with an RS485 interface.
  • Comes with a reset button
  • Comes with a D13 indicator
  • Comes with a XBEE Bluetooth interface
  • Can connect three jumper caps (APC and 485) to switch the XBEE Bluetooth communication or RS485 communication.
  • Comes with I2C, serial port and SPI communication pins
  • Onboard comes with a DC 3.3V output pin
  • Dimensions: 58.5mm x 57.5mm x 20mm
  • Weight: 26.2g
