This compact add-on board connects to EYESPI-compatible displays via an 18-pin 0.5mm pitch FPC connector, giving you a standardised way to wire up SPI displays without a mess of jumper wires.\n\nThe EYESPI standard is like STEMMA QT for displays — a consistent connector and pinout across a range of TFT and E-Ink breakouts. Look for the EYESPI logo on the back of compatible displays.\n\nPin Mapping\n\n\nMOSI / MISO / SCK – Connected to the default SPI port on the QT Py\n\nSDA / SCL – Connected to the I2C port on the QT Py headers (note: some boards have a separate QT Py I2C port on a different bus)\n\nTFT CS – TX pin (reconfigurable via solder jumper)\n\nTFT DC – RX pin (reconfigurable via solder jumper)\n\n\nOptional Pins (Configurable via Solder Jumpers)\n\n\nIRQ on A0 – Used by displays with touchscreens\n\nTouch CS on A1 – For displays with resistive touchscreens\n\nMemory CS on A2 – Used by E-Ink displays with separate SRAM chips\n\nSD Card CS on A3 – For display breakouts with SD card sockets\n\n\nTwo additional through-hole solder pads are provided for Backlight Control and Display Reset, which can be wired with jumper wires if needed. Most displays default these to on, so they're typically optional.\n\nKey Features\n\n\n18-Pin EYESPI FPC Connector – Standardised display connection with flip-top connector\n\nQT Py / Xiao Form Factor – Compact BFF (Board Friend Format) design\n\nConfigurable Pin Mapping – Solder jumpers to reassign or disable CS, DC, IRQ, Touch, Memory, and SD pins\n\nTFT & E-Ink Compatible – Works with any EYESPI-equipped display breakout\n\n\nIdeal For\n\nAdding colour TFT or E-Ink displays to QT Py projects\nCompact display-driven interfaces and dashboards\nWearable or space-constrained builds needing a visual output\n\n\nPackage Contents\n\n1× Assembled and tested EYESPI BFF PCB\n1× Header set\n\n\n\nNote: QT Py / Xiao board, EYESPI display, and 18-pin FPC cable are sold separately.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1554,"title":"Default Title","sku":"AF-5772","price":8.09,"on_sale":false,"in_stock":true,"available_quantity":65,"option1":"Default Title"}]}
