Sinilink XY-WRBT Bluetooth audio receiver module

The Sinilink XY-WRBT is a highly popular and cost-effective Bluetooth 5.0 audio receiver module primarily used in DIY electronics, home audio upgrades, and portable speaker projects. It functions as a lossless decoder, converting wireless signals into analog stereo output accessible through a 3.5mm jack or solder pads. The board is known for its wide voltage support (3.7V to 24V) and compact design.

The product is manufactured in China, specifically within the electronic manufacturing hubs of Guangdong province. It is developed and marketed under the Sinilink (欣易联) brand, which is owned by Qingdao Xinyiyunlian Electronic Technology Co., Ltd. (青岛欣易云联电子科技有限公司). While widely available through various global distributors like AliExpress, DFRobot, and local hobbyist shops, the core engineering and brand management originate from this specialized Chinese IoT and audio technology firm. The module often utilizes Bluetooth chips from Zhuhai Jieli Technology, a prominent Chinese semiconductor company known for consumer audio solutions.
