Quartz Module Datasheet
Document Version 1.1 Arçelik A.Ş. 4
Sensitivity: Confidential
1. INTRODUCTION
Arçelik Connected products require Bluetooth and WI-FI. For this purpose, Quartz
module uses a single chip WIFI, Bluetooth, MCU solution from Espressif Systems,
ESP32-D0WDQ6-V3.
Quartz module is available in three different configurations according to the target
appliance type.
1.1 SPI Interface
For refrigerator products, the quartz module with SPI interface will be used.
1.2 UART Interface
For washing machine, dish washer, dryer, cooker and air conditioner, the quartz
module with UART will be used.
UART/SPI/I2C communication selection will be managed by software and BOM
change.
1.3 I2C Interface
I2C option is also available on this board.
1.4 On-Board Antenna / External Antenna
Wifi and BT connection in the module is provided by a single antenna operating at
2.4Ghz. The module has two different antenna options, internal and external. Default
antenna is on-board (PCB trace) antenna. External antenna is reserved option for
future use.
NOTE: In case of BLE only products, Quartz will not be used and the BLE
funcionallity will be supported by Display MCU.
