This is Revision 1.0 of the R breakout boards. I already made Revision 1.1 before I received these because I realized I needed a few led’s on the board. This board can be used on several R size STM32 MCU’s. The board contain the MCU will all pins available, a SWD connector, PSU and a few leds. Single side assembled only to make it as low cost and simple as possible.
