-====== EVAL-CN0536-ARDZ Shield Overview ======
+===== EVAL-CN0536-ARDZ Shield Overview =====
-Geiger counters are most commonly used by people to measure radiation levels in different specific places. This is a very popular sensor in other countries like Japan that has active nuclear power plants as their source to generate electricity. This type of sensor is sometimes deployed in different places that are linked to the cloud database to monitor dangerous radiation levels that may occur.
+Geiger counters are one of the most commonly used tools to measure radiation levels. This is a popular sensor in other countries like Japan where power is mainly generated from nuclear plants. This type of sensor is generally deployed in numbers across different areas and are linked together to a cloud server for easy monitoring.
-EVAL-CN0536-ARDZ is a low-power Geiger counter radiation detector in an Arduino shield form factor that can run on 3V to 5V system supply. It has a low cost, high voltage generation power supply that is robust and adjustable voltage output from 280V to 500V output. One of the key major part of the circuit in figure 1 is  to generate high voltage output using Analog Devices precision programmable oscillator that is versatile, compact and easy to use LTC6906 that can be set to run oscillate from 10khz to 1Mhz using single user defined resistor value. This reference circuit design is compatible with most of the Geiger-Muller tube sensors available in the market today with a voltage rating between 280V to 500V.
-To set and regulate the high voltage output supply and capture Geiger-Muller tube distinct pulses , the circuit shown in figure 1 has Analog devices LTC1540, a nano power comparator with built in voltage reference to precisely set the user required voltage output and LTC1441 ultralow power dual comparator to translate Geiger pulse to logic level 3V or 5V .

-It has also LT6994 robust built in delay block timer chip that generateS the Geiger clicking sound to a regular buzzer. The LT6994 is a programmable delay block timer with a range of 1µs to 33.6 seconds. The LT6994 is part of
+[[ADI>CN0536 | EVAL-CN0536-ARDZ]] is a low-power Geiger counter in an Arduino form factor that can run on a 3V to 5V system supply. It has a novel architecture for its ultra-low-power, high voltage generator that is robust and adjustable across a wide voltage range allowing the user to set the sensitivity of the board accordingly. This reference circuit design is compatible with most of the Geiger-Muller tube sensors available in the market today with a voltage rating between 280V to 500V.  Moreover, it uses a hysteric voltage regulation scheme by controlling the power supplied to the board oscillator minimizing the overall current consumption. It has a configurable voltage reference for its output allowing the board to safely translate the Geiger pulses to the logic level of the microcontroller. Lastly, it has audio and visual indicators to qualitatively alert the user as the radiation levels increase. \\ \\
-the TimerBlox® family of versatile silicon timing devices.
-A single resistor, RSET, programs an internal master oscillator frequency, setting the LT6994’s time base. The
-input-to-output delay is determined by this master oscillator and internal clock divider.
-The circuit also has LEDs indicating radiation levels , reports counts per minute ,microSieverts per minute via USB UART terminal display or via internet through MQTT.

+==== Board Pinout ====
+The figure below shows the pins used as well as their corresponding functions. It can be seen that the output pin for the Geiger pulse can be set in four different locations. This allows flexibility in case other shields are used together with the CN0536. By default, JP1 is shorted and the Geiger pulse is read from GPIO33. Noting that some pins have specific alternate functions, all other unlabeled pins are free to be used.
