Bracelet Tag T1202W
The circuit of the bracelet tag is roughly the same as that of the name-card style tag T1201C. The difference is that the bracelet tag does not have wireless charging or RFID. The main reason is lack of space.
Because our previous customers basically had no demand for bracelet tags, there was no mass production of bracelet tags.
There was once a customer who wanted a bracelet tag with heart rate detection, and we made a sample, but their project was not completed; another customer wanted to add a display/vibration, and we designed a specially designed one, but this customer later did not have it. continue.
For the standard version of the bracelet tag we designed, the main control MCU was changed to STM32F103TBU6 (QFN package), wireless charging was canceled, the alarm button was canceled, and the anti-tamper function was added. The lithium battery was changed to 600mah, and magnetic charging was used.
