Scrabble sensor board prototype
- To raise interest
- To offer co-operation
- To show the simplicity
See some basic demonstrations
Tournament size, rotation on ball bearing, standard tiles hold NFC tags
Full electronic schematics with explanation
PCB gerber files available. 2-layer standard technology, 2 PCB's.
Embedded C / C++ Arduino
Visual Studio Windows Presentation
Using standard ICode NFC tags, you are not dependent of a single supplier
Reader uses standard 15693 functions.
Low requirements on the microcontroller: 8-bit 20 MHz, 32KB ROM, 2KB RAM, 2KB EEPROM will do
Recent Updates
Currently, a study is ongoing to use the NXP PN5180 multi-protocol reader for future designs! This study is executed with use of the widely available and affordable PN5180 modules. The Github available free libraries have been tested, and improved, and so the same speed is implemented as found with the CLRC632 reader: 9 ms Inventory, 12 ms ReadSingleBlock on one block. Will be continued!
See page Software. Also the method BitwiseID is explained there.
This website has been unchanged for many years. But changes are upcoming: I will publish the software approach, source codes and other details soon!
