Hardware Interface

  • GPIO

  • PWM

  • UART

  • SPI SLAVE

  • I2S Master/Slave

  • Analog Input/Output

Hardware Design Note

  • The simple test of the module only requires connecting VDD/GND/UART_RX/UART_TX to be used

  • After drawing the schematic diagram, please send it to Feasycom for review to avoid the Bluetooth or Wi-Fi distance not achieving the best effect
