描述
MicroPython pyboard IO 擴展板 用於pyboard的 IO 擴展護罩是專為 pyboard v1.1 設計的多功能擴展護罩。它兼容Gravity系列的各種傳感器和電子模塊，即插即用，無需焊接。它不僅可以幫助您避免複雜的佈線，焊接和其他操作，還可以幫助您快速完成佈線並開始使用傳感器或電子模塊，以更快地構建原型。
MicroPython pyboard IO 擴展板 配有外部電源端口和3.3V / VIN電源開關，使擴展屏蔽能夠驅動大電流元件，如電機和伺服電機。擴展屏蔽上有12組數字端口，8組模擬端口，1組串口和2組I2C端口。可以輕鬆連接各種模塊。此外，還有一個板載3.3V LDO，可同時滿足多個模塊的電源需求。更重要的是，RST按鈕和USR按鈕都在屏蔽上，很容易重置或恢復主板。
- 將擴展罩放在pyboard主板上時，請注意方向。擴展屏蔽的導線端子應與pyboard主板的USB端口位於同一側。
- 由於pyboard主板工作電壓為3.3V，受電壓限制，因此不支持5V模擬輸入。所有信號引腳均為0~3.3V。
- 如果需要驅動伺服電機和電機等高電流元件，請將它們連接到X1~X4端口，然後連接外部電源，並將電源開關轉到VIN側。否則，pyboard主板可能會因高電流而損壞。
- X1~X4端口的電源可通過電源開關選擇3.3V或VIN。其餘端口的電源電壓均為3.3V。

Gravity: I/O Expansion Shield for Pyboard
Gravity: I/O Expansion Shield for pyboard is an multifunctional expansion shield specially designed for pyboard v1.1. It is compatible with various sensors and electronic modules of Gravity series, plug and play, no soldering required. It not only helps you avoid the complex wiring , welding and other operations, but also helps you quickly complete wiring and get started with the sensors or electronic modules, to build prototypes faster.
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.
