NUCLEO-F103RB

The NUCLEO-F103RB development board uses the STM32F103RBT6 as the target processor. (The is the same processor used on "Blue Pill" boards.) It was after playing with the "Blue Pill" boards that I decided I need a REAL STMicro development board. This board is a rock solid development board with on-board ST-Link loader / debugger.

Processor: STM32F103RBT6
128KB Flash
20KB SRAM
72MHz clock
Single-cycle multiplication and hardware division
2.0 to 3.6 V application supply and I/Os

Hardware

• Green LED, LD2, connected to PA5, illuminates when driven high
• Blue PushButton, B1, connects to PC13, grounding the signal when pressed
• 32,768Hz crystal oscillator, LSE, used for Real Time Clock (RTC)
• 8MHz HSE, is provided by the 8MHz crystal oscillator from the attached ST-Link, into PD0
• UART2 connects the target processor to the ST-Link, providing a USB COM port connection on the host computer. Uses PA2 for TX, and PA3 for RX.
• ST-Link connects to TCK (PA14), TMS (PA13)
