Basic Raduino Equivilent Functionality:

1 of Arduino NANO board + header pins
    (you can optionally place a 24pin DIP socket for easy replacment of the arduino)
1 of Si5351 Breakout board (Adafruit or Generic) + header pins. (Installed backwards, check pinouts match!!!)
1 of LM7805 voltage regulator.
1 of 10uf 16v Electrolitic capacitor
1 of 220 to 470uf 16v Electrolitic capacitor ( may need to go with a smaller one to get it to fit)
1 of 1uf tantalum capacitor
1 of 10nf ceramic capacitor
4 of  100nf / 0.1uf ceramic capacitor
1 of 39R(thereabouts) 1W resistor.

16 pin female header socket for LCD (or 2x6, middle 4 pins are unused)
8 pin male header pin for DIGITAL Connector (Controls)
16 pin right angle male header pin for OSCiLLATORS ( bitx board connection)

RECOMMENDED that you install the 4 I2C header pins BEFORE the Si5351 board if you plan on doing the I2C LCD or other I2C mods later.

Components are installed on the side of the board that has the outline printed around the holes.

For experimenters, go crazy, all pins are labled on both sides of the board.

I2C Display: Frees up 6 digital IO ports.

1 of LCD I2C backpack and 4 jumper wires.
4 of 4 pin male header for I2C.

Code changes required.

1 of BS170 Mosfet
1 of 1n4148 diode
1 of +-0.5 uf capacitor
1 of 300k 1/4w resistor.

Connect the MUTE pad to your volume control Yellow or Orange wire.
