I’ll take some time to send the Gerber files to a manufacturer. This is the RS485 Prop Controller. In an Arduino Shield-like form factor, this little thing will allow me to put up to 32 microcontrollers on the same RS485 network. The shield can control a load (Up to 24VDC at 1Amp), play MP3 files on a SD Card (Up to 255 files, 32GB Max) and has SPI, I2C, Analog and Digital GPIO’s (Arduino’s Pins, basically). It has 2 RJ45 ports, to put each one of them in series on the RS485 bus.
