The MYC-C8MMX CPU Module is designed by MYIR which is an embedded controller board based on NXP’
i.MX 8M Mini Quad Application Processor. The MYD-C8MMX development board is built around the MYC-C8MMX CPU Module, it is a complete evaluation platform for
your prototype and reference design. It is capable of running Linux and Android OS and provided with plenty of software resources. Typical applications are for Industry Control, Smart City, Smart Home, HMI, Internet
of Things (IoT), etc.
MYD-C8MMX Development Board
The MYC-C8MMX CPU
Module is using the MIMX8MM6CVTKZAA (MIMX8MM6DVTLZAA) processor chip which is
among the NXP i.MX 8M Mini family and combines advanced 14LPC FinFET process
technology to provide more speed and improved power efficiency. It has a quad
Cortex-A53 core which operates at speeds of up to 1.6 (1.8) GHz. It also has a general-purpose Cortex-M4 400 MHz core processor for low-power processing.

MIMX8MM6CVTKZAA (MIMX8MM6DVTLZAA) processor
The chip only has MIPI-DSI and MIPI-CSI interfaces and
no HDMI or other display interfaces. It can support wide working temperature
range from -40 to 105 Celsius degree. MYIR’s MYC-C8MMX CPU Module can support
working temperature from -40 to 85 Celsius degree.

The MYC-C8MMX CPU Module is a minimum system with PMIC, CPU, RAM (DDR4), Flash
(eMMC, SPI Flash) and clock, plus an Ethernet PHY chip. A number of peripheral and IO signals are access through two 0.8mm pitch 100-pin
board-to-board expansion connectors.

The
MYD-C8MMX base board has mainly extended four parts:
1. Audio interface: added audio chip to extend Audio
input and output interfaces
2. External power supply part: added one DC-DC power
chip
3. Added one USB hub chip to extend 4 USB from the SoC
USB interface, separately used for 4G LTE, two USB Host and one USB on
expansion header.
4. Extend RTC module through I2C interface
MYIR
has brought out many other peripheral interfaces for user extension.

MYD-C8MMX Interface Diagram
Among
so many interfaces, Backlight, LVDS LCD and MIPI interface are relative to
display function. The Backlight interface has 6 pins including two power
signals, two GND and two GPIO (one is enabled terminal to control the backlight
power and another is PWM to control the brightness of backlight.)
The two GPIO control terminals are from the GPIO1_01 and 08 of the i.MX 8M Mini.
The
LVDS LCD and MIPI interface, total 3 interfaces are for display. But actually
i.MX 8M Mini only has one MIPI DSI interface. The other two LVDS interfaces are
switched from DSI through one DS12LVDS bridge chip, one is single link LVDS and
another is dual link LVDS. So, we can only select MIPI DSI display or LVDS
display. Also, we can only select single link LVDS or dual link LVDS.
MYIR offers optional LVDS based 7-inch LCD Module MY-LVDS070C including capacitive touch screen to work with
the MYD-C8MMX board. The display resolution is up to 1024 by 600 pixels.
MY-LVDS070C LCD Module
The MYD-C8MMX has one 2.0mm
pitch 2*15-pin male expansion header. PDM and SAI are audio relative interfaces
which are brought out from the expansion header.
Let's see a video introduction of the MYD-C8MMX development board.
