Both boards are functionally identical. I’ve lowered the price on 1.0 boards because people will always choose the higher number.
1.0 uses ARM Cortex-M0 STM32F072C8T6 48MHz
1.1 uses ARM Cortex-M0+ STM32G0B1CBT6 64MHz.
1.2 is pretty much 1.1, but without the firmware heater bug.
Confused yet? Just wait until you start wiring it up.

The 1.0 does have a beneft over the 1.1, as the 1.1 has some issues when in DFU mode. Just pay attention and 1.1 will be just fine. Disclaimer and instructions may be found here: [DISCLAIMER]
G0B1 includes max chip. A31865 DOES NOT.

Perfect drop in replacement for a shorted board. Only took ~ 30 mins to flash firmware and get back to printing.
Followed Eric Zimmerman’s guide with U2C and everything worked perfectly on the first try. Hooked up and tested on bench prior to assembling toolhead
Great price on a great product.
