The ZSB101A from ZHIYUAN Microelectronics employs Nordic’s nRF52820 SoC to provide Bluetooth LE connectivity over extended distances in space-constrained applications
IoT solutions company Guangzhou ZHIYUAN Microelectronics Co., Ltd. has launched a highly integrated module with a form factor of just 8 by 8 by 1.1 mm. The ‘ZSB101A’ module employs the wafer level chip scale package (WLCSP) version of Nordic Semiconductor’s nRF52820 SoC to provide the processing power and Bluetooth® LE connectivity for a wide range of space-constrained applications, including industrial automation, medical devices and sports equipment.
Long range connectivity
In addition to the Nordic SoC, the module also integrates a ceramic chip antenna that helps it achieve a transmission range of more than 100 meters in open spaces according to the company. The nRF52820 SoC’s 2.4 GHz multiprotocol radio features 8 dBm TX power and -95 dBm sensitivity (Bluetooth LE at 1 Mbps) for a link budget of +103 dBm. An external antenna can also be connected to make the design more flexible to address various usage scenarios.
