series:

nRF52840-QIAA

name:

WT52840-S1

 

WT52840-S1 is a high-performance, ultra-low power (Bluetooth Low Energy) RF transceiver system module using Nordic’s nRF52840 as the core processor. The overall size is 27.28*18.74*2.30, which is suitable for most volume requirements. For relatively high application scenarios, the module supports the Bluetooth 5.0 pre-authentication protocol stack S140 driver.

describe

WT52840-S1 is a high-performance, ultra-low power (Bluetooth Low Energy) RF transceiver system module using Nordic’s nRF52840 as the core processor. The overall size is 27.28*18.74*2.30, which is suitable for most volume requirements. For relatively high application scenarios, the module supports the Bluetooth 5.0 pre-authentication protocol stack S140 driver.

The module is used as a master or a slave, and the customer MCU is connected to the module through the UART port. When the module is used as the master, it can scan and search for the broadcast of our WT52810-S1, WT52832-S2, WT52840-S1 series modules to establish a connection. The two-way communication between the two modules can be realized through the serial port. The user can exchange data or control the communication parameters of the module through the UART port. The data meaning is defined by the upper-layer application user. When the module acts as a slave, it can be connected by other mobile devices or the main module, and the APP or host data will be received by the module and pushed to the MCU through UART. After the module receives the data packet from the serial port of the client MCU, it will be automatically forwarded to the mobile device or host.
