Handling and ESD Tips General handling of your TQ-products The TQ-product may only be used and serviced by certified personnel who have taken note of the information, the safety regulations in this document and all related rules and regulations. A general rule is: do not touch the TQ-product during operation. This is especially important when switching on, changing jumper settings or connecting other devices without ensuring beforehand that the power supply of the system has been switched off.
INTRODUCTION The COM Express™ mainboard MB-COME10-1 is a carrier board for COM Express™ modules with Type 10 pinout. It can be used for embedded computers or as evaluation platform for COM Express™ modules. In combination with a standard COM Express™...
UEFI-shell active; no keyboard, no mouse, no mass storage device, no Ethernet cable etc. connected). The maximum input current of the MB-COME10-1 is limited to 5 A by a fuse. The devices connected to the carrier should not exceed 50 W.
DP-LVDS Bridge The MB-COME10-1 is equipped with an NXP PTN3460IBS eDP to LVDS bridge. If a display is connected to eDP the eDP to LVDS bridge will be deactivated automatically. There is also an EDID EEPROM on the MB-COME10-1 where display specific data can be stored.
DisplayPort The MB-COME10-1 supports up to two DisplayPort interfaces. The support of adapters from DP to HDMI, DVI or VGA depends on the combination of the COM Express™ module and the adapter used. The combination of some modules with some adapters might not work.
1 × RS422 (on-board header) The COM Express™ Specification does only provide signal definitions for RX and TX lines for the serial interface. Due to the TQ- flexiCFG feature the serial ports can be configured to route the handshake signals to free pins on the COM Express connector.
RS422 TX+ RS422 RX+ – RS422 TX– RS422 RX+ – – Illustration 7: RS422 Header X25 Not available since signal is not defined in COM Express™ specification. Only available when the TQ flexiCFG feature is available on the COM Express™ module.
3.5.6 Embedded Display Port The MB-COME10-1 supports an embedded DisplayPort (eDP) interface where suitable displays can be connected directly. This functionality is only available for the eDP/LVDS variant. Either eDP or LVDS can be used at the same time. LVDS is only working if there is no display connected to the eDP interface.
The MB-COME10-1 has an on-board EDID EEPROM to store display specific timing information. This EEPROM can be programmed with an external I C programmer. If the programmer supports a 3.3 V output voltage the MB-COME10-1 can be programmed without any additional power supply. In this case no COM Express™ module should be connected to the carrier.
VCC_SWITCHED Backlight voltage output A voltage of up to 30 V can be supplied at this pin. Connect Pin 1 and 2 to use the 12 V of the MB-COME10-1 for the backlight. X32: Backlight connector Connector type: Hirose DF19G-20P-1H Mating connector: e.g.
The Signals for SDIO on COM Express™ modules can also be used as GPIO signals. Please ensure that the module is configured for SDIO-usage of these pins. 3.5.11 Audio The MB-COME10-1 is equipped with an audio codec to support following audio features: • Headphone out •...
5 V Fan Connector X18 3.5.13 Riser Interface The MB-COME10-1 is equipped with a card edge connector for extension purposes. Up to two PCIe cards can be connected to this interface with adapters. For further information about the Riser interface, please contact TQ-Systems GmbH.
SMBus and I C Header The MB-COME10-1 is equipped with a header, the user can easily access to SMBus. The I C Bus (in the TQ-flexiCFG block) can also be accessed here. On this header there is also the possibility to set 2 jumpers for the BIOS disable signals of the module. This header is only used for debug purposes.
SPI Flash Socket The MB-COME10-1 is equipped with a socket for SPI flashes. This is useful if a BIOS update fails or for BIOS development purposes. SPI-Flashes with SO8W package can be inserted. Whether a distinct flash device is supported depends on the COM Express™...
The following illustration shows the MB-COME10-1. Illustration 22: MB-COME10-1 Please contact support@tq-group.com for more details about 2D/3D Step models. Protection Against External Effects The MB-COME10-1 is not protected against dust, external impact and contact (IP00). Adequate protection has to be guaranteed by the surrounding system.
5.1.2 SMBus The SMBus (System Management Bus) on the MB-COME10-1 is connected to the PCIe clock buffer, the MiniPCIe socket and to the Riser interface. It is accessible on the SMBus and I C header. The following table shows the I C address mapping for the COM Express™ SMBus port: Table 21: I C Address Mapping COM Express™...
Measurements for ESD protection have to be done with the electronic parts mounted in a housing. Since TQ- Systems GmbH does not offer a housing for the MB-COME10-1 so far, no special preventive measures were done up to now.
