I built another Radioless node.

This utilizes the Model RL-20 Radioless Adapter from Kevin Custer at Masters Communications.

• Raspberry Pi3 B+
• Alinco EMS-57 Microphone (8pin)
• 3 amp mini 12v-5v buck converter
• PAM8403 3 watt stereo amplifier board MAX98306
• 250k Volume Pot
• 3 watt 4 ohm mini speaker 3inch speaker with grille
• Case TBD

I get asked frequently about how I built my node using the RL-20 Interface so here is a quick schematic I drew showing how I did mine. There are other ways to do this but this worked for me at the time. I may revisit project utilizing some of the features available on the interface board.
