ARM Cortex M3

64 KB SRAM / 512 KB Flash

1. MCU: STM32F103ZET6 from STMicroelectronics, incorporates the high-performance ARM® Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency in LQFP144 package. The STM32F103ZET6 offers high-speed embedded memories(512KB FLASH, 64KB RAM), 12-bit ADC, 12-bit DAC, I2C, SPI, I2S, SDIO, USART, USB, and CAN.
2. Onboard 3.3V regulator, AMS1117-3.3
3. Power indicator
4. User LEDs: These LEDs are connected to the MCU pin via jumpers, used for indicating IO status or program running status while debugging
5. Reset button
6. User Buttons
7. Joystick, 5 directions
8. 8M crystal, enables the MCU run at 72M frequency by frequency multiplication
9. 32.768K crystal, used for internal RTC, also supports clock calibration.
10. Programming interface (JTAG/SWD), onboard 20-pin JTAG/SWD header
11. USB connector, used for establishing USB communication between PC and the STM32 development board
12. USART1 pin header, supports ISP (In-System Programming) through USART1, as well as system signal output
13. IO expander, all the MCU pins are accessible on expansion connectors for further expansion
14. Power input/output header, 5V/3.3V, usually used for power output, or common ground with other user board
15. 5V DC power jack
16. Boot modes configuration: jumpers for selecting STM32 boot space
17. Jumper for selecting power supply, powered from 5V DC jack or USB connection
18. USB enable jumper
    • Short the jumper to enable the PC auto detection while USB connecting
    • Open the jumper to disable
19. VBAT enable jumper, powered from battery is available via this jumper, an external battery is required
20. VREF jumper
