Manufacturing Delays & Limited Availability of Previous-Generation EASE Boards

by Esmacat

Hello everyone,

We have an important question for those of you who backed our campaign. As you may know, there is a nationwide epidemic in China that is delaying PCB manufacturing. Because of this, 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.

We have a few previous-generation EASE boards in our office, however, and we could ship those out in March. We only have six, so we’re offering them on a first-come-first-served basis. If you want your EASE board in a hurry, and if you don’t mind a single missing feature (one that will likely matter to some of you and not to others), please reach out using the Ask…a technical question form on Crowd Supply. And remember to include your order number in your response.

What’s the Difference?

The current version of EASE (v1p15) supports SPI communication through the ICSP pins, which allows it to communicate with the entire Arduino ecosystem. The earlier revision (v1p12) is identical to the v1p15 except that the ICSP pins are not connected to EASE, and therefore SPI cannot be accessed through them. As a result, it can only communicate with Arduino Unos and other MCU boards that support SPI through pins 11, 12, and 13 (with pin 9 or 10 as CS).

So, if you’re only planning to use your EASE with an Arduino Uno, please let us know, and we’ll get it to you as soon as possible.

Sorry about the delay, but we are excited to see what you all create with EASE!!!
