This is a hardware project for Ka-Radio.

It is based on ESP8266 chip and audio codec VS1053b chip.

• You can power it with 3V3 or 5V (5V can be from 4V to 6V). Do NOT use both power inputs at the same time.

• You can connect an external keypad for control. Just unsolder the ADC jumper.

• The RXD pin is 5V tolerant so you can connect a 5V microcontroller.

• Output is line-out with large audio grade electrolytic capacitors. Safe to connect an external amplifier.

• You can use two types of SRAM. 23LCV1024 or 23LC1024. Just solder the proper jumper.

You can order the pcb from OSH Park. I also have a few boards assembled and tested to sell. E-mail for details.
