Description

The DFPlayer board is a small compact self contained module with an ATTiny 85 controller, voltage regulator and volume switches. It is great for adding audio to scale model projects, Halloween displays or anything else you can think of.

Two of the ATtiny IO lines are used for interfacing with the DFPlayer. You can use a full serial connection or just send commands to the DFPlayer and monitor the busy line. This leaves pins 2,6, and 7 for external IO to further control the DFPlayer.

Additional IO connections for the DFPlayer include IO, ADKEY, Volume Up/Down (Using the IO pins), DAC L/R and a Speaker connection. Connections can be soldered to the board or 0.1" headers can be used.

A schematic is available along with a Bill of Materials (BOM).

About PCBWay Services

PCBWay's web site makes it real easy to upload a design and select any options you would like. I really liked the fact that they do a design check first before they request any payment. Once the design has been approved and payment complete the turn around is very fast. Some of my recent PCB designs are a bit unique with a perf-board like top layer and a mixed through hole surface mount on the bottom and PCBWay has made these boards with out issue. The fabrication quality is very good. The majority of my boards are small run prototypes and PCBWay does these at very reasonable prices. If you are not comfortable with PCB layout PCBWay offers that service as well. They also offer PCB Assembly and CNC/3D printing. PCBWay makes PCB design fast, easy, and affordable.
