SBC-C43

1.4 Safety

The SBC-C43 board uses only extremely-low voltages.

While handling the board, please use extreme caution to avoid any kind of risk or damages to electronic components.

1.5 Electrostatic discharges

The SBC-C43 board, like any other electronic product, is an electrostatic sensitive device: high voltages caused by static electricity could damage some or all the

devices and/or components on-board.

1.6 RoHS compliance

The SBC-C43 board is designed using RoHS compliant components and is manufactured on a lead-free production line. It is therefore fully RoHS compliant.

Always switch the power off, and unplug the power supply unit, before handling the board and/or connecting cables or other boards.

Avoid using metallic components - like paper clips, screws and similar - near the board when connected to a power supply, to avoid

short circuits due to unwanted contacts with other board components.

If the board has become wet, never connect it to any external power supply unit or battery.

Check carefully that all cables are correctly connected and that they are not damaged.

Whenever handling an SBC-C43 board, ground yourself through an anti-static wrist strap. Placement of the board on an anti-static

surface is also highly recommended.

SBC-C43

2.1 Introduction

SBC-C43 is a Single Board Computer, measuring just 102 x 146 mm (4,02 x 5,75 ) based on embedded NXP i.MX 8 Family, featuring multicore processing (Single

or Dual ARM Cortex®-A72 cores + Quad ARM Cortex®-A53 cores + Dual general purpose Cortex®-M4 processor).

Graphics features of the board are managed directly by NXP i.MX8 processor, which integrate 2x Graphics accelerators Vivante GC7000 / XVSX or GC7000 Lite /

XVSX (QuadMax and QuadPlus) GPUs, supporting OpenGL® ES 1.1 / 2.0 / 3.0 / 3.1, Open CL 1.2 OpenGL 3.x, DirectX 11. This family of processors integrate

one embedded VPU, which allows HW acceleration for video decoding of H.265 (4K30), H.264 (1080p60) and encoding of H.264 (1080p30).

The board is completed with up to 8GB LPDDR4 directly soldered on board, and one eMMC Flash Drive, directly accessible like any standard Drive, with up to 64GB

of capacity. Mass storage capabilities are completed by a microSD Card slot. External SSD modules can expand mass storage capabilities through M.2 Key B Slot

with S-ATA interface (factory option with PCIe x1 for plugging M.2 Modem modules)

The processor offers two RGMII interfaces which, through dedicated Ethernet Transceivers, allows the implementation of two Gigabit Ethernet interfaces.

The communication / networking capabilities of the board are completed by an M.2 Key B Slot, which allows plugging M.2 Modem modules with USB or PCI-e

interface, an M.2 Key E Slot, which allows plugging M.2 WiFi + BT modules with USB or PCI-e interface and by an optional WiFi a/b/g/n/ac + BT LE 4.2 combo

embedded module, with ceramic SMT antennas on-board.

The M.2 Key B Slot can rely on an on-board microSIM slot.

The SBC-C43 offers an USB 3.0 Standard Type-A connector (combo with RJ-45 GbE connector), one USB 2.0 standard Type-A connector (combo with RJ-45

GbE connector), an internal USB 2.0 header and one USB 2.0 with OTG functionalities on micro-AB socket.

The audio functionalities of this board are realised by an I2S audio codec, which manages Line out and Mic In interfaces on a combo TRRS audio jack.

The standard functionalities of this board are then completed by 3x UART interfaces (RS-232, RS-485/RS-422, TTL level), an I2C interface, four A/D inputs, an SPI

interface, 6x GPIOs and three CAN Bus interfaces.

The board is available both in commercial and in industrial temperature range.

Please refer to following chapter for a complete list of all peripherals integrated and characteristics. Not all combinations of these features are offered simultaneously;

please visit SECOs website for a description of standard configuration modules offered. Configurations different from the standard offered must be evaluated

singularly; please contact a SECO s sales representative / distributor for this.

** Measured at any point of SECO standard heatspreader for this product,

during any and all times (including start-up). Actual temperature will widely

depend on application, enclosure and/or environment. Upon customer to

consider application-specific cooling solutions for the final system to keep the

heatspreader temperature in the range indicated.

Please also check paragraph 4.1

SBC-C43

2.3 Electrical specifications

SBC-C43 needs to be supplied only with an external 12VDC ± 10% power supply, with a minimal 60W power rating (SBC-C43 power consumption

by itself is around 18W, more power is required for the possible attached devices).

This voltage can be supplied through a Right-angle connector type Molex Mini-Fit Jr, p/n 39-30-0040 or equivalent, with the pinout indicated in the

table below.

Power available

When powering SBC-C43 with a PSU with characteristics greater or equal to the one described at beginning of previous paragraph, please consider well what is the

typical scenario for using the board (i.e., which peripherals will be connected)

Since all the power must be supplied by an external PSU only, please balance well the typical final configuration, considering both the power consumption of the

board itself and the power consumption of external devices.

This way it is possible to calculate preliminarily if a 60W PSU can be sufficient for system needing or if most powerful PSUs are required.

•16GB eMMC onboard

•HDMI FHD display connected (no additional peripherals)

RTC Battery

The SBC-C43 board can be equipped with an optional low-power Real Time Clock embedded on the module (which is a NXP PCF2123).

If the board is not equipped with the optional rechargeable battery, then it will be available a soldered horizontal 3V coin cell lithium battery to supply the RTC.

The battery used is a not-rechargeable CR1225 Lithium coin-cell battery, with a nominal capacity of 48mAh, , to supply such an RTC. The battery must be plugged

on the onboard battery holder CN43.

In case of exhaustion, the battery should only be replaced with devices of the same type. Always check the orientation before inserting and make sure that they are

aligned correctly and are not damaged or leaking.

Never allow the batteries to become short-circuited during handling.

CAUTION: handling batteries incorrectly or replacing with not-approved devices may present a risk of fire or explosion.

SBC-C43

Batteries supplied with SBC-C43 are compliant to requirements of European Directive 2006/66/EC regarding batteries and accumulators. When putting out of order

SBC-C43, remove the batteries from the board in order to collect and dispose them according to the requirement of the same European Directive above mentioned.

Even when replacing the batteries, the disposal has to be made according to these requirements.

Power rails naming convention

In all the tables contained in this manual, Power rails are named with the following meaning:

_RUN: Switched voltages, i.e. power rails that are active only when the board is in ACPI’s S0 (Working) state. Examples: +3.3V_RUN, +5V_RUN.

_ALW: Always-on voltages, i.e. power rails that are active both in ACPI’s S0 (Working), S3 (Standby) and S5 (Soft Off) state. Examples: +5V_ALW, +3.3V_ALW.

_U: unswitched ACPI S3 voltages, i.e. power rails that are active both in ACPI’s S0 (Working) and S3 (Standby) state. Examples: +1.5V_U

Other suffixes are used for application specific power rails, which are derived from same voltage value of voltage switched rails, if it is not differently stated (for

example, +5VHDMI is derived from +5V_RUN, and so on).

SBC-C43

2.4 Mechanical specifications

Board dimensions are 146 x .

The printed circuit of the board is made of ten layers, some of them are ground planes, for disturbance rejection.
