BLE mesh development boards and kits

Brief Introduction:

This experiment box is used in the test development of Nrf52832 chip, supporting J-Link tool, and provides relevant application reference examples.
There are buttons, indicators, LCD display, relays, buzzers, ultrasonic ranging module, infrared sensor module, USB to serial port, light and temperature and humidity sensors and universal interface pins on the board, which are suitable for testing and verification of basic functions.

Function Function description of each part

The NRF52832 is a 32-bit ARM microcontroller with integrated BLE wireless communication. Integrated Bluetooth low power BLE, SPI, I2C, serial port, ADC, RTC and other rich peripheral resources.
The development board consists of five parts: baseboard (JO-0710-3-1), LCD module (JO-0710-3-2), BLE module (JO-0710-1-2), infrared module (JO-0710-3-3) and ultrasonic module (JO-0710-3-4).

The comprehensive experimental projects that can be realized are:

BLE light control experiment	BLE serial transmission experiment
BLE data transmission control experiment	BLE temperature and humidity acquisition experiment
BLE light intensity experiment	BLE photoelectric sensing experiment
BLE potentiometer experiment	BLE buzzer experiment
BLE relay experiment	BLE infrared experiment

The baseboard comes with the following resources:

  1. Power switch: The power switch is used to cut off or connect the external 5V power supply or USB power supply.
  2. RGB LED switch: used to choose to use RGB lights or LED1-LED3.
  3. Press the RESET button. Press the low level for external reset.
  4.4 Keys K1-K4: Press the low level.
  5.4 LED LED1-LED4: low level light.
  6.1 RGB indicators: corresponding to LED1-LED3 respectively.
  7.1 USB ports: USB to serial port function, and can be used as power supply.
  8. J4/J5: including chip function, power supply, LED light load operation pin.
  9. J10: Connects to J-Link for debugging and downloading programs.
  10. U5: Connect the BLE module JO-0710-1-2.
  11. Light sensor: OPT3001 sensor, I2C slave address 0x45.
  12. T/H sensor: sht30 sensor, I2C slave address 0x44.
  13. Rheostat: for ADC testing.
  14. Buzzer.
  15. Relays.
  16. Ultrasonic module and infrared module interface.
