Pin # Pin Name Pin Description Input/output
1 – 2 3p3 volts (3V3) 3.3 Volts DC Input to EXP1 from uEZGUI Power
3 – 5 5volts (5V0) 5.0 Volts DC Output to uEZGUI Power
6 USBD_VBUS
VBUS – Monitors the presence of USB bus power. Note: Must be HIGH for USB reset to occur.
(USB Device port on uEZGUI-EXP1)
Input
7 USBD_DM USB_D-2 – USB port 2 bidirectional D –line (USB Device port on uEZGUI-EXP1) Input / Output
8 USBD_DP USB_D+2 – USB port 2 bidirectional D+ line (USB Device port on uEZGUI-EXP1) Input / Output
9 P0.2_TXD0 TXD0 – Transmitter output for UART0. (for RS232) Output
10 P0.3_RXD0 RXD0 – Receiver input for UART0. (for RS232) Input
11 ISP_ENTRY
I/O – P2[10] – General purpose digital input/output pin. Note: LOW on this pin on NXP LPCXXXX
while RESET is LOW forces on-chip boot loader to take over control of the part after a reset.
