The first boards have finally shipped! Another great milestone, after a long wait. All outstanding orders will be shipped over the next few days. We have a small stock at this time as we decided to hurry production for the first batch, but the next shipment is expected to arrive soon.
The Megatronics v3 datasheet and start guide is now available from the product page. Sources will be available soon.
Also I released a new Marlin remix for megatronics (v2 and v3). There is now full support for our keypad. See the software downloads page fo the most current version.
