{"title":"Adafruit RGB Matrix HAT + RTC for Raspberry Pi - Mini Kit","handle":"adafruit-rgb-matrix-hat-rtc-for-raspberry-pi-mini-kit","url":"/products/adafruit-rgb-matrix-hat-rtc-for-raspberry-pi-mini-kit","description":"The Adafruit RGB Matrix HAT + RTC makes it easy to drive HUB75-type RGB LED matrices from your Raspberry Pi. This HAT plugs onto any Pi with a 40-pin GPIO header and includes a DS1307 real-time clock, so your Pi can keep accurate time even after reboots or power loss — perfect for clock and time-based display projects.\n\nThe HAT features built-in level shifters (3.3 V to 5.0 V) and power protection circuitry that guards against negative, over, or under-voltage from the 5 V supply. This is a mini kit requiring some light soldering to attach the headers — most beginners can complete it in about 15 minutes.\n\nKey Features\n\n\nDS1307 Real-Time Clock – Keeps time even when the Pi is rebooted or powered down (CR1220 coin cell required, sold separately)\n\nPower Protection – Built-in circuitry guards against negative, over, or under-voltage from the 5 V supply\n\nOnboard Level Shifters – Converts the Pi's 3.3 V logic to 5.0 V for clean, glitch-free matrix driving\n\nHUB75 Compatible – Works with 16×32, 32×32, and 32×64 RGB LED matrices\n\nChainable Displays – Connect multiple matrices for longer displays (recommended maximum 32×128)\n\n\nCompatibility\n\n\nSupported Pi Models – Raspberry Pi Model A+, B+, Pi 2, and Pi 3 (any 40-pin GPIO header model)\n\nMatrix Type – HUB75 RGB matrices only (not for NeoPixel, DotStar, or other addressable LEDs)\n\n\n\nNote: RGB LED matrix, 5 V power supply, Raspberry Pi, and CR1220 coin cell battery are sold separately. To calculate power requirements, multiply the total pixel width of all chained matrices by 0.12 A (e.g. a 32-pixel-wide matrix may draw up to ~3.85 A, so a 5 V 4 A supply is recommended).\n\n\nIdeal For\n\nTime displays and clocks with accurate RTC timekeeping\nScrolling text displays and signage\nMini LED video walls and art installations\nInformation dashboards and status boards\n\n\nPackage Contents\n\n1× RGB Matrix HAT PCB (surface-mount parts pre-assembled)\n1× 2×20 female socket connector\n1× 2-pin terminal block\n1× 2×8 IDC socket connector\n\n\nResources\n\nAdafruit RGB Matrix HAT + RTC Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":9241,"title":"Default Title","sku":"AF-2345","price":51.65,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
