PCBA Usage Guide
Version 1.0, 8/2021
REVISION HISTORY
Initial Release based on internal specification
INTRODUCTION / OVERVIEW
The KDP HMI 10 is a custom PCBA, based on a Quad-core Cortex-A53 with 1GB
LPDDR2 DRAM for use as a human-machine interface (HMI) controller.
An HDMI-to-MIPI display circuit is added for display panel connection.
USB Hub provides 4 USB Type-A ports, touchscreen, along with custom cellular
and camera connections.
SPECIFICATIONS
PROCESSING CORE
− 64-Bit, Quad-core ARM A53 SoC
− Heat sink for passive heat dissipation
− 1GB LPDDR2 DRAM
− WiFi/BT, 2.4GHZ, 802.11bgn
INPUT POWER
− Voltage: 12V +/- 10% DC Input
− Power: 12W minimum, 18W recommended
− Minimum recommended wattage includes:
− All onboard devices
− 2.2W for the display
− 2W for added peripheral devices installed onto the connectors
ENVIRONMENTAL
− Ambient Operating Temperature Range: -20°C to 70°C*, non-condensing humidity
− Storage Temperature Range: -40°C to 85°C, non-condensing humidity
*Note: depending on processor workload, CPU throttling may occur above
50C ambient
DIMENSIONING & MOUNTING
− PCBA Dimensions: 146mm W x 75mm D x 20mm H (mating cables will require
additional height and depth)
− Designed to mount to plate attached to the back of custom touchscreen
display
BOOT IMAGE / STORAGE MEDIUM
− 16GB (minimum) eMMC onboard
LED INDICATORS
− Onboard Power / Activity LED
− PWR: Green LED indicates valid power
− ACT: Yellow flashing indicates disk activity by default, but configurable
− Onboard User LEDs
− Green
− Controlled from user code using GPIO (LED1 and LED2)
USB 2.0
A USB 2.0 High-Speed Hub provides seven (7) downstream connections. All
downstream ports share a single USB 2.0 High-Speed connection back to the
processor. This limits maximum shared bandwidth of all USB devices to
~250Mbit/s. All USB connections include ESD protection.
DISPLAY CONNECTION
The display connection consists of several separate circuits:
− HDMI-to-MIPI bridge chip provides the signaling for the display
− LED backlight driver with PWM brightness control
− USB touchscreen interface
− I2C interface for ambient light sensor (ALS) connection

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the
following measures:
− Reorient or relocate the receiving antenna.
− Increase the separation between the equipment and receiver.
− Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
− Consult the dealer or an experienced radio/TV technician for help.
ISED COMPLIANCE STATEMENT
This device contains license-exempt transmitter(s)/receiver(s) that comply
with Innovation, Science, and Economic Development Canada’s license-exempt
RSS(s). Operation is subject to the following two conditions:
(1) This device may not cause interference.
(2) This device must accept any interference, including interference that may
cause undesired operation of the device.
RADIATION EXPOSURE STATEMENT
This equipment complies with FCC/IC RSS-102 radiation exposure limits set
forth for an uncontrolled environment. This equipment should be installed and
operated with a minimum distance of 20 cm between the radiator and your body.
