RS485 to RJ45 Ethernet Module - Common Ethernet Port (B) _MAKE_POWER_BATT The EKMB-series PIR sensors are

The EKMB-series PIR sensors are optimized for small movements to offer motion-sensing options for battery-powered applications due to the low standby current draw of the sensor (1µA)

however they usually come with a lot of pin connections and a single backlight colour

two extended/stackable 1×6 female headers (for Arduino shields)

Note: this is a newest upgrade version of TB6600 stepper motor driver

RS485 to RJ45 Ethernet Module - Common Ethernet Port (B) _MAKE_POWER_BATT The EKMB-series PIR sensors areThis is an RS485 device data acquisitor IoT gateway designed for the industrial environment. It combines multiple functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON and more. The module features RS485 and Ethernet ports, uses screw terminals for power input and supports 9~24V wide range power supply in a rail mount flame retardant case design. Small in size and easy to install, it is suitable for applications such
