1 PRODUCT

1.1 Function description
CSM3510 Bluetooth module is adopted the core SOC CSU8DL3510 chip, supports Bluetooth

4.0 protocol, supports UART, SPI interface. The module can switch among different
mode ,including broadcast mode, transmission mode and sleep mode. CSM3510 is used for
Bluetooth slave mode block, working voltage is from 2.0V to 3.6V, transmit power is from +
8dBm to - 7dBm, broadcast, transmission mode for each frame data is 20 byte

1.2 Main characteristics

1.3 Power consumption

Note：Average current test method: Using the uA stall of multimeter to view the display data

between the battery and the module, the test voltage is 3.0V. The transmit power is set to 0dBm
