ماژول HC-42 یک ماژول با قابلیت پشتیبانی از بلوتوث ورژن 5 مبتنی بر چیپ NRF52832 است و دارای جریان مصرفی خیلی کم 1.23 میلی آمپر در حالت کار با سطح بالا و جریان 75uA در حالت سطح پایین است.
Description:
This HC-42 module is a nrf52832 based bluetooth module. With a small size and cheap price, it is very easy to embed this module into many projects that require bluetooth. It also breakout pins from nrf52832 so you can use it as a MCU to control other devices without adding additional MCU.
The module’s setting can be re-configured by AT command.
The module uses half-holes design to breakout, so it is very convenient for both prototype and mass production.1. Guide :EN, VCC, GND & RXD, TXD, STATE, STATE are blue state, Outputs low when not connected, and outputs high when connected.
2. Voltage specification :The input voltage is 3.2-6V, the power supply comes with anti-reverse connection, and the reverse connection does not work.
3. Status Indicator :Before the connection, it lights up for 1 second every 2 seconds. After the connection, the LED is bright
4. Interface level :The interface TTL level is 3.2 to 6V, which can be connected to various single-chip microcomputers (Arduino, 51, AVR, P °C, ARM, MSP430, etc.), 5V microcontroller can be directly connected. Direct connection to the microcontroller. The serial port cannot pass through the MAX232 chip.
5. Communication distance :The effective communication distance in the open environment is 40M
6. Communication format:After the pairing is successful, it can be used as a full-duplex serial port. No need to know any Bluetooth protocol, but only support 8-bit data bit, 1-bit stop bit, no parity communication format. This is also a common communication grid.
Other formats are not supported.
7. Default value: baud rate 9600, Bluetooth name HC-42
