-## Older Version ##
+## Previous Versions ##
-Easy Mini [version 1.0](v1.0) was largely the same design but used a
-different processor.
+All versions of EasyMini have the same user-visible features and
+specifications, the differences are primarily in the choice of processor which
+has changed over time due to availability.
+
+Easy Mini version 1.0 was the first production version of EasyMini, based on
+the [NXP LPC11U14](http://www.nxp.com/products/microcontrollers/cortex_m0_m0/LPC11U14FHI33.html) System-on-Chip.
+
+Easy Mini version 2.0 was the second production version of EasyMini,
+based on the
+[STM32F042](http://www.st.com/en/microcontrollers/stm32f042f6.html)
+System-on-Chip. This version also moved to a more robust USB connector.
+
+Easy Mini version 1.1 was the third production version of EasyMini. It used
+the more robust USB connector, but went back to the same processor chip as
+version 1.0 due to parts availability.
