1. Functional Characteristics
Mouselet-B is based on CYPRESS Bluetooth chip CYW20736, designed specifically for BT
light control module(BLE), can be widely applied in the field of short-range wireless
communications for all occasions, it has small size, low power consumption,
transmission distance, anti-interference ability, and low cost.
The module antenna is a ceramic antenna that made the overall design compact and
miniaturization. The interface is also completely open, customers in the use of RF
hardware design eliminates the difficulty, while the software and product structure has
more flexible secondary development space.
The module has a UART interface, The UART is a standard 2-wire interface (RX and TX)
and has adjustable baud rates from 9600bps to 1.5 Mbps. The baud rate can be selected
via a vendor-specific UART HCI command. The interface supports the Bluetooth 3.0
UART HCI (H5) specification. The default baud rate for H5 is 115.K baud. Both high and
low baud rates can be supported by running the UART clock at 24 MHz. The CYW20736
UART operates correctly with the host UART as long as the combined baud rate error of
the two devices is within ±5%.
The module also has a SPI interface.The interface has a 16-byte transmit buffer and a
16-byte receive buffer, to support more flexibility for user applications.
