UART Interfaces¶
The xPico 600 module supports one serial port with flow control.
Pin Description of UART Interfaces
| Pin Name | LGA Pin No. | M.2 Pin No. | Alternate Function | I/O 1 | Description |
|---|---|---|---|---|---|
| GPIO_00 | 17 | 36 | UART0_CTS | DI | UART0 clear to send |
| GPIO_02 | 20 | 32 | UART0_RXD | DI | UART0 receive |
| GPIO_03 | 19 | 22 | UART0_TXD | DO | UART0 transmit |
| GPIO_05 | 8 | 34 | UART0_RTS | DO | UART0 request to send |
The default baud rate for serial port is 9600 bps.
The UART connection between the module and MCU is illustrated below; flow control pins are optional.
For the serial port leading to the test point, the reference design is shown below.
