This expansion shield is equipped with an external power supply port and a 3.3V/VIN power switch, which makes the expansion shield able to drive high current components such as motors and servos. There are 12 sets of digital ports, 8 sets of analog ports, 1 set of serial port and 2 sets of I2C ports on the expansion shield. Various modules can be easily connected to it. Additional, there is an onboard 3.3V LDO, which meets the power demand of multiple modules at the same time. What’s more, the RST button and the USR button are all on the shield, which is easy to reset or restore the motherboard.
Attention：
- When put the expansion shield on the pyboard motherboard, please pay attention to the direction. The wire terminal of the expansion shield should be on the same side as the USB port of the pyboard motherboard.
- Because pyboard motherboard works at 3.3V, limited by the voltage, it does not support 5V analog input. All signal pins are 0~3.3V.
- If you need to drive high current components such as servos and motors, please connect them to X1~X4 ports, then connect the external power supply, and turn the power switch to VIN side. Otherwise, the pyboard motherboard may be damaged due to high current.
- The power supply of X1~X4 port can be selected 3.3V or VIN by the power switch. The power supply voltage of the remaining ports are all 3.3V.
