PoStep60-256 microstep stepper motor driver 24 modification

Microstep stepper motor driver – 24V signals

PoStep60-256 microstep stepper motor driver can operate also on 24 V controll signals. PoStep60-256 microstep stepper motor driver is normally operating on 5V inputs for step, direction and enable signals. Most industrial PLC controllers provide only 24V signals. However adding simple 1,2 kOhm resistor in series with controll input will make PoStep60-256 microstepping stepper motor … Read more

PoKeys57CNCcase-COLLAGE

Machinable case design for PoKeys57CNC motion controller

Although PoKeys57CNC devices are sold as ‘naked’ boards, the board itself can be used to make a case. How? Simply, employ the device as the USB or Ethernet motion controller for CNC device and machine one out of a solid block of metal or plastic. Our user Roman Batz carefully designed the case and provides … Read more

Raspberry Pi data logger

Raspberry Pi data logger with PoKeys as a data acquirer

Versatility of PoKeys device makes it well suited as a component of an environment monitoring system. PoKeys device functions as a data acquisition point, as many different sensors can be easily connected to it. Acquired data can we store directly with PoKeys software logger or send to local, for example Raspberry Pi, data logger or … Read more

Raspberry Pi Relay module

Relay module for Raspberry Pi PoRelay8 – Part 2 (CAN bus)

First part of this blog Raspberry Pi relay module PoRelay8 – Part1 was about connecting and controlling single PoRelay8 board with Raspberry Pi. Relay board and Raspberry Pi were communicating over I2C bus. Setup in this example has two limitations.  First, I2C bus was developed for communication between devices on same PCB and can be … Read more

PoKeys meets ThingSpeak – reporting data to IoT cloud

Late in December Xively IoT platform has announced retirement of its free service Xively Personal, support for which was already integrated into our Ethernet PoKeys devices. One of possible alternatives is ThingSpeak IoT platform. Free version offers up to 3 channels, each can contain 8 data fields. Number of messages is limited to 3 million … Read more
