Manufacturing Delays & Limited Availability of Previous-Generation EASE Boards

As a result of manufacturing delays in China, our latest order has been pushed back by at least a month. We now expect those boards to ship in late-April or early-May. However, we have six previous-generation EASE boards (v1p12) that we could ship out in March. The only difference is a lack of support for SPI communication through the ICSP pins. Because of this, the v1p12 revision only works with Arduino Uno MCU boards. If you're interested, let us know using the "Ask...a technical question" form on Crowd Supply. (And please include your order number.) Read the full update.

Deploying Esmacat Master Code; Funding Goal Reduction

In this update, we will demonstrate how simple it is to build and execute the Esmacat Master software for EASE. You can think of this software as a way for multiple EASE boards (and other EtherCAT slaves) to communicate with one another by reading values from one slave and writing to another. Any EtherCAT master software will work with EASE, but we are focusing here on our own free and open source code. Read the full update.

A Few of Our Tutorials

As we mentioned in our launch announcement, we are striving to provide our future users with strong supporting material to showcase EASE's capability, versatility, and usability for anything from hobbyist projects to automation industry prototypes and beyond. In this week's update, we are highlighting three examples tutorials found on our Hackster.io page. Read the full update.
