Product Information
Key Specifications/ Special Features
Product Parameters
1. Onboard RTC battery holder
2. Onboard power status indicator light
3. Working voltage: DC5V
4. Reserve multiple plugin pads for easy secondary development
Product Description
This product is an SD card expansion board used for storing data and providing data transfer protection. The module is equipped with a four channel buffer with three state output control to control data writing and output. When the chip enable terminal is equal to 0, it can be read and written normally; When the enable terminal is equal to 1, it is in a disabled state, and the output terminal is in a high impedance state. In order to ensure stable communication between the product and other modules, the module is equipped with a real-time clock IC and a dedicated RTC battery holder. The product is available in two types: with and without batteries.
There is a physical reset button on the board; SDS slotting; Power indicator light, allowing users to easily observe the current power status of the module; And two undefined LED lights (L1, L2) are reserved for users to design according to their own needs.
