What's On Board

1. ESP32-S3R8
   Dual-core processor, up to 240MHz operating frequency
2. 16MB Flash
3. Battery recharge management chip
4. Amplifier chip
5. ES8311
6. ES7210
7. Microphone
8. MP1605GTF-Z
   Power module, supports up to 3.3V 2A output
9. Onboard ceramic antenna
10. IPEX1 connector
    for connecting external antenna, enabled via resoldering an onboard resistor
11. BOOT button
12. GPIO1 function selection resistor
    soldered on the side near the crystal by default: the GPIO1 pin is used for battery voltage measurement.
    resoldered to the other side: the GPIO1 connects to the17.FPC connector, enabling three-screen display function through software modification
13. Battery header
    MX1.25 2PIN connector, for 3.7V Lithium battery, supports charging and discharging
14. Charge indicator
    Lithium battery charge indicator, lights up when charging, off when fully charged (the light status is uncertain when the battery is not connected)

15. Speaker header
16. SH1.0 14PIN header
17. 18PIN FPC connector
    for three-screen display function by resoldering the12.resistor and modifying the display configuration parameters in the program.
    when the board is split into two halves, this FPC connector can be linked with18.FPC connector so that both displays function properly (Note: when the board is split and connected via FPC cable, the RESET button will be unavailable)
18. 18PIN FPC header
    for connection to the host
19. TF card communication mode selection
    when the board is split into two halves, switching to SPI mode allows the TF card to be controlled by an external master controller.
20. TF card slot
    Supports high-capacity TF cards
21. RESET button
22. SH1.0 14PIN cable header
    for controlling TF card and the LCD display via SPI interface when the board is split into two halves and resoldering19.resistor to SPI mode
23. Type-C port
