J122. It allows a UART connection between the
target MCU and board/module attached to the
socket, using its pin 2 (RXD) and pin 4 (TXD).
FC2
mikroBUS socket connector J8. It allows a
UART connection between the target MCU and
click board plugged into the mikroBUS socket,
using its pin 3 (RX) and pin 4 (TX).
2.5 I2C interface
The target MCU has an I2C module, which can be accessed using its Flexcomm modules 0-7. In the LPC55S36-EVK board, the
I2C module is accessed using Flexcomm modules 1, 3, and 7 of the target MCU.
The figure below shows the I2C diagram of the LPC55S36-EVK board.
