1. The RESERVED pin and unused pins need to be suspended.
2. All GND pins should be connected to ground.
3. The module provides 1 UART, 1 USB interface, 2 analog audio interfaces and 44 GPIO interfaces
by default. In the case of multiplexing, it supports up to 48 GPIO interfaces, 2 SPI, 1 QSPI, 3
UARTs, 1 SDIO interface, 2 I2C interfaces, 1 CAN interface
*
, 1 LCM interface, 12 PWM interfaces,
1 I2S interface, and 8 SAR ADC interfaces. For more details, see
