The main control chip CC 2540U 1 is an ultra-low power consumption Bluetooth radio frequency single chip microcomputer.
The SPX3819M5-3.3 chip U7 of the power supply circuit is responsible for converting the external +5V power supply voltage into the +3.3V power supply voltage used by the single chip microcomputer and ensuring the normal work of the single chip microcomputer. In addition, the +5V power supply voltage is used as four groups of carbon fiber material heating power supplies. The power circuit is provided with a direct current power supply access end, a +5v direct current voltage output end and a +3.3v direct current voltage output end.
The low-power-consumption operation oscillation circuit mainly comprises a low-frequency 32.768K crystal oscillator X2 and two capacitors C20 and C21, and is connected to a main control chip CC 2540U 1 in parallel, so that the main control chip U1 works in a low-power-consumption mode.

The four carbon fiber materials can be respectively controlled to be heated to different temperatures.
