Operation Instructions

Waterproof mobile phone case
The circuit board system is divided into LED circuit board, charging circuit board,
switching circuit board, analog-to-digital conversion circuit board and electric regulating
circuit board. The power supply of LED circuit board, switching circuit board and
analog-to-digital conversion circuit system is 3V, and the component power supply is
maintained by ZL6205A30TS5. The system power supply of the electrical control circuit
board is 4.2V, and the components are maintained by ZL6205A30TS5 to maintain the
stability of 3V power supply. The charging circuit board is powered by 5V, and 4.2V power
supply is maintained by TP4059.
The main control chip NCH-RSL10-101Q48-ABG is a 3V power supply,
programmable master chip. Main functions: collect and process the operation instructions
transmitted from the antenna and control the light panel display.
The switch circuit sends the signal to the antenna, and the antenna transmits the
received signal to the main control chip. The main control chip controls the light panel
display by collecting and processing the signal.
