1 Preface
As a member of PHYTEC's new phyBOARD®product family the phyBOARD‑Mirai.MX6 is one of a series of PHYTEC
System on Modules (SBCs) that offer off-the-shelf solutions for a huge variety of industrial applications. The new
phyBOARD®product family consists of a series of extremely compact embedded control engines featuring various
processing performance classes. All phyBOARDs are rated for industry, cost-optimized, and offer long-term
availability. The phyBOARD‑Mira i.MX 6 is one of currently six industrial-grade carrier boards that are suitable for
series production and that have been realized in accordance with Phytec's new SBCplus concept. It is an excellent
example of this concept.
1.1 SBCplus Concept
The SBCplus concept was developed to meet fine differences in customer requirements with little development
effort and thus greatly reduce the time-to-market.
The core of the SBCplus concept is the SBC design library (a kind of construction set) that consists of a great
number of function blocks (so-called "building blocks") which are refined constantly. The recombination of these
function blocks allows for the development of a customer-specific SBC within a short time. Thus, PHYTEC is able to
deliver production-ready custom Single Board Computers within a few weeks at very low costs.
The already developed SBCs, such as the phyBOARD‑Mira, each represent an intersection of different customer
wishes. Because of that, all necessary interfaces are already available on the standard versions, thus, allowing them
to integrate into a large number of applications without modification. For any necessary detail adjustment,
extension connectors are available to enable adding of a wide variety of functions.
1.2 Cost-optimized with Direct Solder Connect (DSC) Technology
At the heart of the phyBOARD‑Mira is the phyCORE-i.MX6 System on Module (SOM). As with other SBCs of the
phyBOARD®family, the SOM can be directly soldered onto the carrier board PCB for routing signals from the SOM to
applicable I/O interfaces. This optional “Direct Solder Connect” (DSC) of the SOM eliminates costly PCB to PCB
connectors, thereby further reducing overall system costs, and making the phyBOARDs ideally suited for
deployment into a wide range of cost-optimized and robust industrial applications.
1.3 Customized Expandability from PHYTEC
Common interface signals route to standard connector interfaces on the carrier board such as Ethernet, CAN,
RS-232, and audio. Due to the easily modifiable phyBOARD design approach (see "SBCplus concept"), these plug-
and-play interfaces can be readily adapted in customer-specific variants according to end system requirements.
Some signals from the processor populating the SOM also extend to the expansion, and A/V connectors of the
phyBOARD‑Mira. This provides for customized expandability according to end-user requirements. Thus
expandability is made easy by available plug-and-play expansion modules from PHYTEC.

The default orientation of the expansion bus connectors is parallel and on the top side of the carrier board PCB.
However, in custom configurations, the connectors can be mounted on the PCB's underside. Connectors in
perpendicular orientation can also populate the top or underside of the PCB. This enables maximum flexibility for
the orientation of expansion modules on the phyBOARD‑Mira, as well as the integration of the system into various
end application physical envelopes and form factors.
1.4 Easy Integration of Display and Touch
The phyBOARD and its expansion modules enable easy connection of parallel or LVDS-based displays, as well as
resistive or capacitive touch screens.
1.5 OEM Implementation
Implementation of an OEM-able SBC subassembly as the "core" of your embedded design allows you to focus on
hardware peripherals and firmware without expending resources to "re-invent" microcontroller circuitry.
Furthermore, much of the value of the phyBOARD®SBC lies in its layout and test.
1.6 Software Support
Production-ready Board Support Packages (BSPs) and Design Services for our hardware will further reduce your
development time and risk and allow you to focus on your product expertise.

2.1 Conventions
The conventions used in this manual are as follows:
Signals that are preceded by an "n", "/", or “#” character (e.g.: nRD, /RD, or #RD), or that have a dash on top
of the signal name (e.g.: RD) are designated as active low signals. That is, their active state is when they are
driven low or are driving low.
A "0" indicates a logic zero or low-level signal, while a "1" represents a logic one or high-level signal.
The hex numbers are given for addresses of I2C devices always represent the 7 MSB of the address byte. The
correct value of the LSB which depends on the desired command (read (1), or write (0)) must be added to get
the complete address byte. E.g. given address in this manual 0x41 => complete address byte = 0x83 to read
from the device and 0x82 to write to the device.

3 Introduction
3.1 Hardware Overview
The phyBOARD‑Mira for phyCORE-i.MX 6 is a low-cost, feature-rich software development platform supporting the
NXP Semiconductors i.MX 6 microcontroller. Moreover, due to the numerous standard interfaces the
phyBOARD‑Mira i.MX 6 can serve as the bedrock for your application. At the core of the phyBOARD‑Mira is the
PCM‑058/phyCORE-i.MX 6 System On Module (SOM), containing the processor, DRAM, NAND Flash, power
regulation, supervision, transceivers, and other core functions required to support the i.MX 6 processor.
Surrounding the SOM is the PBA‑CD‑06/phyBOARD‑Mira carrier board, adding power input, buttons, connectors,
signal breakout, and Ethernet connectivity amongst other peripherals.
The PCM-058 System On Module connects to the phyBOARD‑Mira carrier board by the use of two high-density
connectors. The phyBOARD‑Mira is also available with the phyCORE-i.MX 6 in a direct solder form factor (PCL-058), a
connector-less, BGA style variant of the PCM‑058/phyCORE-i.MX 6 SOM. The PCL-058 SOM is directly soldered down
to the phyBOARD‑Mira using Phytec's Direct Solder Connect technology. This solution offers an ultra-low-cost
Single Board Computer for the i.MX 6 processor, while maintaining most of the advantages of the SOM concept.
Adding the phyCORE-i.MX 6 SOM into your own design is as simple as ordering the connector version (PCM-058) and
making use of our phyCORE Carrier Board reference schematics.

4.2 Functional Components on the phyBOARD-Mira SBC
This section describes the functional components of the phyBOARD‑Mira. Each subsection details a particular
connector/interface and associated jumpers for configuring that interface.
4.2.1 Power Supply
4.2.1.1 Power Connectors (X2)
The phyBOARD‑Mira is available with two different power supply connectors. Depending on your order you will find
one of the following connectors on your SBC:
a 2-pole Phoenix Contact MINI COMBICON base strip 3.5mm connector (X2) suitable for a single 5V supply
voltage, or
a 6-pole WAGO male header (X2) to attach the Power Module for phyBOARDs (PEB‑POW‑01) which provides
connectivity for 12V – 24V
The required current load capacity for all power supply solutions depends on the specific configuration of the
phyCORE mounted on the phyBOARD-Mira, the particular interfaces enabled while executing software, as well as
whether an optional expansion board is connected to the carrier board.
FIGURE 4: Power Supply Connectors (X2), Backup Voltage Connector (X29)
Phoenix Contact 2-pole MINI COMBICON Base Strip (X2)
The permissible input voltage is +5 V DC if your SBC is equipped with a 2-pole Phoenix Contact MINI COMBICON base
strip. A 5 V adapter with a minimum supply of 1.5 A is recommended to supply the board via the 2-pole base
strip.Power Supply Connectors(X2), Backup Voltage Connector (X29)and the following table show the pin
assignment.
Warning
Do not change modules or jumper settings while the phyBOARD‑Mira is supplied with power!
