-The [[[smoothiepanelalpha|original plan to use an ARM Cortex-M0 MCU]]] has been brought back out and dusted off because the open source tool-chain is ready! Also, there were some periodic issues with the [[[Smoothiepanel-beta|Beta design]]] that used I2C port expanders. In the end came down to line noise from using I2C over cables in a noisy environment. That brings us to the [[[Smoothiepanel-gamma|Gamma design]]]. I went back to using an MCU but I went with a USB capable chip. It still has the Nunchuck port of course but has also gone back to the original idea of customizable / replaceable interface panel. There was then a Delta design that fixed a couple hardware bugs in the Gamma design and added the character lcd footprint back in.+The [[smoothiepanelalpha|original plan to use an ARM Cortex-M0 MCU]] has been brought back out and dusted off because the open source tool-chain is ready!
