Description The 4D Pi Serial Adaptor (4D-Serial-Pi-Adaptor) is a simple Raspberry Pi* adaptor designed to provide a convenient interface to attach 4D Systems display modules to the Raspberry Pi platform, without having to use jumper wires on the Raspberry Pi headers. The 4D Pi Serial Adaptor is included in various 4D Systems PI Module Packs but can be purchased separately if a 4D Display Module is not required or is owned already. Communication to the 4D Systems Display Modules is performed via the Raspberry Pi's serial port (RX and TX) and is provided to the user in a simple 5-pin interface, where a 5-way cable (included in the -PI Module Packs) can be attached between the adaptor and the Display Module. Power for the display is supplied from the Raspberry Pi's 5V bus. No external power is required for the Display Module as all power is supplied from the Raspberry Pi, via the Adaptor. Please ensure the Raspberry Pi is powered with a suitably powered 5V power pack. The 4D Serial Pi Adaptor is compatible with versions A, B and B+ Raspberry Pi's. The 4D Serial Pi Adaptor is compatible with essentially all 4D Systems Intelligent Displays, primarily the following: • uLCD-24PT • uLCD-28PT • uLCD-32PT • uOLED-96-G1/G2 • uOLED-128-G1/G2 • uOLED-160-G1/G2 • uLCD-144-G1/G2 • uLCD-43 (All versions) • uLCD-24-PTU • uLCD-28-PTU • uLCD-32-PTU • uLCD-32W-PTU • uLCD-35DT • uLCD-70DT • uLCD-220RD The 4D Raspberry Pi Library is available to download from the 4D Systems website. 4D Systems DATASHEET Page 3 of 5 4D Serial Pi Adaptor Description 4D Pi Serial Adaptor 4D Pi Serial Adaptor attached to a Raspberry Pi 4D Pi Display Module Pack (4D Pi Serial Adaptor is one part of this pack) Note Raspberry Pi remains the property of the Raspberry Pi Foundation.
