The USB Connector-sized Open Stepper!

Most of you here must have been involved with Open stepper motors before, but have you ever saw the mini size Open Stepper? If you haven’t and you’re wondered what the actual appearance of this Open stepper, then you should get yourself into this Open stepper development project. From the above figure, you will find out that this Open stepper motor is about the size of the USB connector, which it’s very small enough and you can put it into your pocket easily! This Open Stepper Module (OSM) is comprised of a GSM_01 and the Open Stepper circuit board. The OSM firmware is based on Mike Thompson’s popular Open Servo project, where Jay Ragsdale was the person that ported it to the ATtiny84. Beside that, Jay has written the low-level drive algorithm that makes this code work with a stepper motor. Since this is a smart Open stepper motor, thus it can be controlled via a daisy chained serial connection, where it could make it simple to interface with complex projects. Hopefully, you’ll enjoy this Open stepper motor project and… Continue reading
