+# LINE Things Development Board
+The LINE Things development board is powered by [Nordic Semiconductor's nRF52832] (https://www.nordicsemi.com/Products/Low-power-short-range-wireless/nRF52832), in which the specific module used is the [Raytac MDBT42Q] (http: // www.raytac.com/product/ins.php?index_id=31). This development board is for experimenting with LINE Things. It actually consists of two boards, the first being the core or the CPU board, and the other is the peripheral board or the daughterboard. After verifying the functionality of a concept through the daughterboard, the core can be removed to be placed into a breadboard for custom board designs and prototyping.

+## Peripherals on the daughter board
+**NOTE 5V systems and 3.3V systems cannnot be directly connected to one another.**


There are 3.3V and 5V devices on the board.
On board battery can only supply 3.3V. So, can not work 5 V device.for example, motors.
When use external or USB power, 5V and 3.3V are provided and all devices can be used.

+### Buzzer
+A piezoelectric buzzer is included. To make the buzzer sound, you will need to provide an AC signal from the microcontroller. Setting the pin to HIGH will not cause the buzzer to make a sound. Normally on a regular Arduino, you would be able to use the tone() function to create such signals, however the timer in the nRF52832 is incompatible with this library. Therefore, you will need to generate the signal yourself through timers, interrupts, etc. In the sample provided, we take advantage of FreeRTOS's timer to generate a 1KHz interrupt to toggle the pin state which creates a 500Hz signal to make the buzzer sound. If you want to change the pitch of the buzzer, you will need to play around with the timers. 
+You can use the tone () function to produce any sound with regular Arduino, but you can not use this with the nRF52832 Arduino environment.

+ * When using the CPU core as a standalone, ensure the antenna sits as far away from the breadboard as possible (preferably the edge of the breadboard) to avoid any interference. Additionally, any GND wiring and planes as well as any RF signals near the attena can cause interference.
+ * For a reliable connection and communication, make sure to keep the antenna as exposed as possible. Avoid metallic enclosures as it can block BLE signals. Plastic enclosures are highly advised.
