The Gravity I/O Expansion Shield for Pyboard v1.1 is a remarkable multifunctional add - on. It's fully compatible with a wide range of Gravity series sensors and electronic modules. With its plug - and - play design, you can ditch the soldering hassle. This shield simplifies your work, letting you avoid complex wiring and welding. You can quickly wire up sensors or modules and start building prototypes in no time. It comes with an external power supply port and a 3.3V/VIN power switch, empowering it to drive high - current components like motors and servos. There are 12 digital ports, 8 analog ports, 1 serial port, and 2 I2C ports, making it a breeze to connect various modules. An onboard 3.3V LDO ensures that multiple modules get the power they need. The RST and USR buttons on the shield are very convenient for resetting or restoring the motherboard. The color - coded Gravity connector is a great feature, enhancing its compatibility. Specifications include an external power supply voltage of 5 - 12V, and other detailed parameters. It comes with product documentation and one unit in the shipping list.
Using the Gravity I/O Expansion Shield for Pyboard v1.1 is easy. First, when you put the shield on the pyboard motherboard, make sure the wire terminal of the shield is on the same side as the USB port of the motherboard. Since the pyboard motherboard works at 3.3V, it doesn't support 5V analog input, so keep in mind that all signal pins are in the 0 - 3.3V range. If you want to drive high - current components like servos and motors, connect them to the X1 - X4 ports, then plug in the external power supply and switch the power to the VIN side. Otherwise, the high current might damage the pyboard motherboard. The power supply of the X1 - X4 ports can be set to 3.3V or VIN using the power switch, while the other ports are all 3.3V. For maintenance, just keep it in a dry and clean place. If there's dust on it, you can use a soft brush to gently clean it. Also, check the connectors regularly to make sure they're in good condition.
