The evaluation board is based on CH9141K and is made according to the schematic diagram shown below. The minimum system circuit of the CH9141K is very simple, requiring only one crystal oscillator and two capacitors. After powering the evaluation version (2.5-3.6V), data transmission between the serial port and Bluetooth can be easily realized.<\/p>\n
