The included RDID card has 1K memory, it has 16 sections with 3 blocks each. ![](https://kittenbothk.readthedocs.io/en/latest/_images/IMG_2583.GIF) ### Details ![](https://kittenbothk-eng.readthedocs.io/en/latest/_images/10_031.png) ### Specifications * Voltage: 3V-5V * Dimensions: 56mm X 56mm X 16mm * Connector: 4Pin PH2.0 * Sensing Distance: Approximately 3cm ### Precautions * Do not use the module in an environment with strong magnetic fields. * Any metal between the reader and the card will cause it to fail to write or read. * It may take sometime when writing a large amount of data into the RFID Card, please wait until the light goes off. * Cards like Octopus Cards or ID Cards have encrypted data, the reader can only read the UUID of these cards. ### Connecting the module #### Armourbit *** Connect the RFID Module to the I2C port of Armourbit with a 4Pin cable. ![](https://kittenbothk.readthedocs.io/en/latest/_images/rfid_wire.png) #### Robotbit *** Connect the RFID Module to the I2C port of Robotbit. ``` Blue(A)->SCL, Green(B)->SDA ``` ![](https://kittenbothk.readthedocs.io/en/latest/_images/rfid_wire1.png) ### MakeCode Coding Tutorial ![](https://kittenbothk-eng.readthedocs.io/en/latest/_images/mcbanner.png) #### Load Powerbrick Extension: #### Search "Powerbrick" in the search bar. ![](https://kittenbothk.readthedocs.io/en/latest/_images/powerbrick_search.png) #### Or search the following link. #### RFID Module Blocks ![](https://kittenbothk-eng.readthedocs.io/en/latest/_images/rfidblocks1.png) #### Writing data onto RFID Card {% embed url="" %} [Sample Program](https://makecode.microbit.org/_XdP0Pye1rFA0) #### Reading Data from RFID card {% embed url="" %} [Sample Program](https://makecode.microbit.org/_TEz6D45qgDaa) #### Reading the UUID Every RFID card has an unique ID. {% embed url="" %} [Sample Program](https://makecode.microbit.org/_a6wiKdUqWaXL) #### Identification with UUID We can use UUID to identify indicviduals. {% embed url="" %} [Sample Program](https://makecode.microbit.org/_c4rcrE76Tc6Y) #### Makecode Vidoe {% embed url="" %} #### Demo Video {% embed url="" %} ### Extension Version and Updates[](https://kittenbothk-eng.readthedocs.io/en/latest/functional_module/PWmodules/powerBrickRFID.html#extension-version-and-updates) There may be updates to extensions periodically, please refer to the following link to update/downgrade your extension.
