Description
LPC5536JBD100 (U28)
Target MCU. It acts as I2C master on the board.
FC1
LPC55S69JBD100 (U16)
MCU-Link. A USB-to-I2C bridge is supported
between MCU-Link and the target MCU using an
I2C repeater / a voltage translator (U27). Jumper
JP4 can be used to enable/disable the USB-to-
I2C bridge.
