Carrier board Expansion Header
Expansion connector is a 40-pin header which contains I2Cs, UARTs, eCSPI, PWM, GPIOs
and power for user use.
UART interface support the following serial data transmit/receive protocols and
configurations:
•
7- or 8-bit data words, 1 or 2 stop bits, programmable parity (even, odd or none)
•
Programmable baud rates up to 4 Mbps. This is a higher max baud rate relative to
the 1.875 MHz, which is stated by the TIA/EIA-232-F standard.
•
32-byte FIFO on Tx and 32 half-word FIFO on Rx supporting auto-baud
UART4_TXD, UART4_RXD can be configured as UART2_RTS and UART2_CTS respectively.
I2C interfaces which provide serial interface for external devices. Data rates of up to 400
kbps are supported
WB10-AT SOM supports one full-duplex Enhanced Configurable Serial Peripheral
Interface (ECSPI). The ECSPI contain a 64x32 receive buffer and a 64x32 transmit buffer.
The ECSPI power domain is VDDIO_3V3.
