Quartz Module Datasheet 7 HARDWARE STRUCTURE 7.1 Communication interface Quartz module has two separate 2.5mm pitch board edge connectors. Connector (KN1) to be used in the cable group of the module is given in the following file. 57441 30000.pdf (Top View) PIN#1 PIN#1 Power and Communication Connector (KN1) Document Version 1.1 Sensitivity: Confidential Programming Connector (KN2) Arçelik A.Ş.
Quartz Module Datasheet 7.1.1 KN1 Pin Order – Communication and Power Connector Quartz module will support UART, SPI and I2C Communication protocols. Only one of these three protocols will be active in the module. The protocol to be used will be managed by software and BOM variation. SPI and UART interfaces are 5V logic and I2C interface is 3.3V logic. Main board or display board communication interfaces must be compatiable with the required logic level of Quartz module. Pin No.
Quartz Module Datasheet 7.2 Antenna Configuration The Quartz module supports external and on-board antenna. Antenna option to be used and the placement of the antenna is one of the most critical parameters in terms of wifi performance of the final product. By default, module uses on-board (PCB Trace) antenna. To use the external antenna, position and placement in the final product should be decided with the approval of the Central R&D RF specialist. PCB Antenna (IFA) U.
Quartz Module Datasheet 7.2.1 On-Board Antenna Figure 9: S22 Measurement of Antenna Worst case efficiency was measured at 2475MHz -1.4443 dB (71.71%) with the peak gain of 4.4979 dBi. Further details for Antenna measurements can be found in the following document. QUARTZ_ESP_G01 .pdf Note: Final test report from the test lab will be attached when available. Document Version 1.1 Sensitivity: Confidential Arçelik A.Ş.
Quartz Module Datasheet 7.2.2 External Antenna 50ohm U.FL connector option is available on Quartz module for external antenna connection. This type of 50 ohm connector is manufactured by different manufacturers under different names (AMC, UMCC, IPX) and in different sizes. Technical drawing of the connector used in the Quartz module is given below. On the external antenna, it is important that the cable matches the connector specified in the technical drawing.
Quartz Module Datasheet 7.2.3 Antenna Placement Following figure shows desired position of antenna for good RF performance. Similarly, if another metal structure is present, the same conditions apply. In cases where this guide cannot be followed, support should be requested from central R&D RF engineer for antenna placement. In cases where the mechanical structure is not suitable, an external antenna solution can also be applied, explained in previous section. Document Version 1.
