SmoothiePanel is an Open Source Hardware integrated PanelMax.
The goal is to bring a 20x4 Character Display with RGB Backlight, RGB illuminated click-encoder, and illuminated Play and Back buttons down to a single I2C port.
The basic interface panel supports an illuminated pause button, an illuminated back button, an RGB Click Encoder, a Wii Nunchuck, and lots of extra I/O.
It is intended to control a Smoothieboard (GPL too), though could easily be connected to any system with available I2C.
The original plan to use an ARM Cortex-M0 MCU has been put on hold until the open source tool-chain is ready.
A new beta version has just been prototyped based on I2C port expanders from NXP.
The current status of this board is prototyping: I’m now on the beta version of the board.
It is fully functional and basic code has been merged into the edge branch of Smoothieboard.
Going with a system that didn’t require its own firmware really sped things along.
Smoothiepanel lives!
There are currently a couple prototypes of the beta Smoothiepanel still available.
There are a LOT of options in building one.
If you would like one of the prototypes, email me (reprap at logxen dot com) and if there are still any proto PCBs left I will send you a price list back for configuring your kit.
Or you can simply make yourself known by emailing here (reprap at logxen dot com) and you’ll be added to the list of interested people.
No strings attached, it’s just to help us plan.
