NEXT VERSION

Planning on a bit of a pivot. The 2nd version will be much simpler breakout board, making the design usable with any 3.3V microcontroller the user chooses:

• DRA818[V,H] Transceiver module
• Mini-circuits LPF
• Voltage Divider for DRA's MIC in to interface with a 3.3V DAC
• N-Ch MOSFET for 3.3V Logic to drive DRA's Push To Talk
• LM358 OpAmp to boost DRA's AF Out to 0..3.3V range for microcontroller Analog In
• 12V to 5VDC Voltage Regulator
