iMX RT1062 OEM Developer’s Kit - User’s Guide
Copyright 2019 © Embedded Artists AB
Due to signal integrity of the high-speed signals, three signals are not available per default at
the TPx access pads described in section 4.5 . The stubs to the access pads are removed
from the tracks by not having R150, R151 and R152 not mounted. The affected signals are:
GPIO_SD_B0_01 - mount R150 to access the signal via TP69
GPIO_SD_B0_03 - mount R151 to access the signal via TP73
GPIO_SD_B0_05 - mount R152 to access the signal via TP75
R150-R152 can be found on the bottom side, just under the middle of the SODIMM
connector and under the LCD. R150-R152 are 0 ohm 0402 resistors.
4.11 SP10: LCD Interface
There is a 4.3 inch LCD with capacitive touch panel and 480x272 pixel resolution that is mounted on
the bottom side. The 40 position FPC connector (J18) to the LCD has a relatively common pinning that
will match many other LCDs. Since all relevant signals of the parallel RGB interface are available on
the connector it can be used as a general display expansion connector - with the help of a small
custom adapter board (to the display in mind).
The parallel RGB interface of the i.MX RT1062 is configured to 16-bit color depth (5 bits for red, 6 bits
for green and 5 bits for blue).
Communication with the capacitive touch panel controller is done via I2C and two GPIOs, one for reset
and one for interrupt.
There is a backlight current generator that is set to 40mA. It can optionally be controlled with a PWM
signal to dim the backlight.
4.12 SP11: Ethernet Interface
The board has an Ethernet interface, J20, which is a RJ45 connector with integrated magnetics. See
picture below for where to find the location of J20.
