Clone PI AVR metal board is fully soldered and tested with an embedded microcontroller, LCD display with a solder loop for connecting to the board and a buzzer. Clone PI AVR is a microprocessor-based pulsed metal detector with automatic coil tuning, the metal detector has high sensitivity and is able to work with coils of various sizes from 20 cm to depth frames up to 2 meters in diameter. Using this board, you can assemble both a conventional soil impulse metal detector and a deep metal detector to search for large metal at a depth of up to 3-4 meters.
 

This kit includes:

1.   Clone PI-AVR ready module 
 2.   Plastic box D110B (110*92*68mm) 
 3.   Connector for coil GX16-2 
 4.   Connector for battery DC5525 
 5.   Scheme and instruction in English   

 Some features of our Clone PI-AVR ready module   
 All microcircuits on the board are installed on the panels, for the convenience of changing the firmware in the microcontroller and its further maintenance.   
The control of the metal detector is carried out by four buttons installed on the board. The board is fully tested, configured and ready to work, you need to connect a coil, power and a toggle switch to it, to connect them screw terminals are installed on the board. 
The metal detector operates on a voltage of 9-15 volts, it is recommended to use a 12 volt battery, or 3 series-connected lithium-ion 18650 batteries for power supply.   In search mode, the metal detector on the display shows the current supply voltage, the set sensitivity threshold, volume level, and when metal is detected, a signal level scale appears.   

In the Clone PI AVR metal detector menu, you can configure the following parameters:  
  •  Adjust the volume level. 
  • Turn on the display backlight. 
  • Minimum supply voltage. 
  • Guard interval (coil setting). 
  • Type of detuning from the ground. 
  • And a sound indication circuit.
