MiniPIIO RS485 module for Raspberry Pi PCB Only
The MiniPiio RS485 is a RS485 to TTL 3.3V converter board specifically designed to work with your Raspberry Pi.
Its compact design is a quick and easy solution to adding RS485 communications to your Raspberry Pi Projects.
The MiniPiio RS485 uses 3.3V components and is completely voltage compatible with the Raspberry Pi.
The board connects directly to the Raspberry Pi's UART Rx and Tx to provide RS485 half-duplex communications.
The board uses the industry standard MAX3485* for signal conversion.
An industry standard 9-Way D Connector (Male) and a 3-W screw provides provides the serial connection to the outside world.
Pin-out (9W D):
Pin-5 = 0V Pin-8 = B (Data +) Pin-9 = A (Data -)
Note: GPIO signals are required to control the MAX3485* DE and !RE.
PIIO and MiniPIIO are modular electronic building block for the Raspberry Pi and may be used with our RPi Expander2.
*or Equivalent IC
Uses 3.3V MAX3485* IC Standard 9-Way D Connector 3-Way 3.81mm Screw Terminal RS485 Half-duplex communications Selectable 120R terminating resistor Uses Raspberry Pi Expansion Connector Suitable for standard TTL 3.3V input. Board Dimensions: 50 x 40 mm
