Product Name:BLE Smart Modules Mesh Network ADC Resolution I2C Communication Bluetooth AI Intelligent Display

Feature

●The main chip uses Nordic nRF52832.

●In order to meet the needs of customers, we can provide modules and APP software according to customer needs.

●Support language recognition function.

●The module power supply range is 1.7V to 3.6V.

●Module power consumption: 3.3V/current is less than 5.4mA.

●SWDIO and SWDCLK pins are software upgrade pins.

●Serial port user optional interface.

●Optional settings Baud rate 1200 to 256000, data bits: 8 bits: 1 bit, with/without parity bit, with/without flow control, (default is 115200).

●Support I2C communication.

●Support Mesh network function.

●ADC resolution 8/10/12bit, input voltage range 0 to 3.6V (VCC is 3.6V), can support 2 channels.

●Pin 4 is the RESET pin, which is the module reset pin. It is reset at a low level. The internal pull-up resistor is included and can be suspended.

●Pins 2, 3, 6, 7, 8, 9, 12, 13, 14, 17, 18, 19 are all GPIO interfaces.

●Pins 2, 3, 6, and 7 can be configured as JTAG interfaces (TMS, TCK, TDO, and TDI).

●Pins 8 and 9 can be configured as I2C interfaces (SDA, SCL).

●Pins 12 and 13 can be configured as UART interfaces (RX, TX).

●Pins 8 and 9 can be used as ADC input interface.

●Other unused pins can be suspended.

●The module includes two types with and without shield.

●The module defaults to the patch method. To ensure the optimization of BLE performance, it is recommended that the antenna part of the module and other metal parts.The distance should be at least 15mm.

●Working environment temperature -40 to 85 degrees.

●Support BLE module temperature detection is automatically turned off when it is greater than 40 degrees.

●Support time switch function.

●Support random switch function.
