SmoothiePanel was an Open Source Hardware integrated panel design using the LPC 1114 ARM Cortex-M0 chip.
It was designed to bring a 20x4 RGB Character Display, UART, SPI, 4-bit ADC, and 16-bit GPIO down to a single I2C port.
The basic interface panel was to support:
It was intended to control a Smoothieboard though it could easily be connected to any system with available I2C.
The status of this board as of 2013 was prototyping: design was done, and the first prototypes had arrived and were being assembled by hand.
The firmware was never completed.
This project was never released to the public and remains an abandoned prototype.
The Smoothiepanel firmware was designed for maximum usefulness in mind, allowing replaceable and extendable user interface panels.
Since it was all Open Source Hardware, the design could have been reworked to support communication styles other than I2C, or custom firmware could have been written to use a Smoothiepanel LCD Backpack as the core of other projects.
Since the SmoothiePanel project was never completed, consider these alternatives:
The most popular panel option for Smoothieboard.
Features a graphical LCD with SD card slot and rotary encoder.
Advanced panel with larger screen and more features.
Allows connection of various standard RepRap panels to Smoothieboard.
