For Micropython Programming STM32 Development Board pyboard v1.1-CN + USB Cable
Description:
With one Micro USB cable, you can start your development projects now! Just 2 rows of codes to make LED lit.
For pyboard v1.1-CN:
It fits for pyBoard v1.1 and has improved some functions:
1. Rearranged buttons and LED make it user-friendly
2. Added XH-2.54 2P port for power supply input on the back side
3. Screen printing changed for better 
V+: 3.6-6V input (It is recommended to use USB port to power. When it is powered via USB port, it is 5V.)
3V3: 3.3V output with maximum current 250mA.
VBAT: Power supply input. (On-board FET protection circuit. XH-2.54 2P port on the back side)
VBACK: Backup power supply input
A3V3: Analog reference voltage. Connect to 3V3
X9 / X10 is in I2C mode when using on-board three-axis accelerometer
X17: When you press USR button, X17 will connects to GND through 4.7k resistor
P2-P5 connect to 4 LEDs which will be lit when IO outputs high level.
SD_SW = A8 to check whether SD card is inserted to switch
MMA_INT = B2 is used to receive interrupts generated by the on-board accelerometer
MMA_AVDD = B5 pin connected to AVDD of on-board accelerometer
BOOT0 connects to 3V3, and it will enter into DFU mode after resetting
Package Included:
- 1 x Board
- 1 x Micro USB Cable
Note: Battery is not included in the package.
