Introduction
The MK-070C is the newest family mem-
ber in the Amulet Display Module product
line. The new 7” Capacitive Display Module
incorporates Amulets new high performance
Graphics Display Card. The Display Card is
based around a 540Mhz ARM A5 processor
architecture and is the next generation of
HMI cards. The MK-070C has 4GB of DDR2
RAM, 4GB eMMC Flash module, and SD card
socket with support over 64GB. The module
has an 800x480 WVGA TFT LCD with a pro-
jected capacitive touch panel.
The High Performance Graphics Display Card
integrates the Amulet Graphical OS (GEM
OS) with the high performance, cost-sensi-
tive, processor architecture of the ARM Cor-
tex series. Capable of executing 840 DMIPS
aided by an integrated LCD controller with
graphics accelerator and floating point unit
(FPU) for faster data processing, the Graphics
Display Card is the perfect solution for any
integrated, embedded, HMI solution.
The MK-070C-HP, 7” Projected Capacitive
Display Module is the perfect solution for any
high performance graphical user experience.

1. Mini-USB input power supply: This
port designated J18 on the PCB is just
one of many methods to power the dis-
play module. The power supply must be
5V ± 5%, supplying at least 1A.
2. Mini-USB device programming port:
When connected to the PC, the device
will be recognized as a USB Mass Storage
Device. Within GEMstudio Pro, Amu-
let’s integrated design environment, the
compiled projects will get stored in the
onboard eMMC.
3. µSD card slot: The external SD card
has two functions. Display projects can
be updated using the SD card. During
boot, the project on the SD card can be
read and written onto the eMMC directly.
The SD Card can be used for data stor-
age with the read/write function accessed
through read/written to from GEMscript.
Note: the µSD card is not supplied with
the module.
4. Battery Backup: the function of the
battery backup is to keep the RTC (Real-
Time Clock) operating even with the loss
of module power. The battery used is the
CR1225 3V watch battery. Note: the bat-
tery is not supplied with the module.
5. FPC (Flat Panel Cable) connector for
touch panel signals.
6. Reset switch.
7. Power cable for the LCD backlight.
