[Introduction]:The E104-BT52X-V5.3 is a low-power Bluetooth module based on the dialog DA14535 chip, the BLE5.3 protocol, and the IPEX-3 antenna interface. It supports Bluetooth host, slave, master-slave, and observer modes, and AT command parameter setting. It also supports low-power broadcasting, data transparent transmission, and over-the-air configuration. It can be widely used in smart wearables, smart security, smart homes, industrial Internet, smart data acquisition, and smart control.
| Serial number | Pin Name | Pin direction | Pin Function | illustrate |
| 1 | GND | input | Power ground | |
| 2 | VL- | -- | Low voltage power supply pin | Low voltage power supply pin, users do not need to worry about |
| 3 | VCC | input | Power positive | Power supply positive (short connected to pin 4 "VH+" when in use) |
| 4 | VH+ | input | Power positive | Power supply positive (short connected to pin 3 "VCC" when in use) |
| 5 | GND | input | Power ground | |
| 6 | GND | input | Power ground | |
| 7 | RST | input | Reset pin | Low level reset (takes about 500ms to take effect) |
| 8 | PART | input | SWEDING | SWDIO, JTAG interface, users do not need to care |
| 9 | NC | -- | NC | Users don't need to care |
| 10 | CLK | input | SWCLK | SWCLK, JTAG interface, users do not need to care |
| 11 | NC | -- | NC | Users don't need to care |

| 17 | DATA | Output | data | Data indication pin Note: Receiving Bluetooth data: When there is Bluetooth data in the air, the DATA pin will be pulled high when it is sent through the TXD pin of E104-BT52/E104-BT52X/E104-BT52-V5.3/E104-BT52X-V5.3. After a frame of data is sent, the pin will be pulled low again. Send Bluetooth data: The DATA pin buffers 1024 bytes of data after receiving data at the RXD pin of the E104-BT52/E104-BT52X/E104-BT52-V5.3/E104-BT52X-V5.3. As long as there is data in the BUFF that has not been sent via Bluetooth, the DATA pin will be pulled high and will not be pulled low again until the data in the BUFF is sent. When sending data, users can frame the data as described above. |
