SKU: AF-6130 · MPN: ADA6130

The Adafruit Feather RP2350 with HSTX Port and 8 MB PSRAM is the upgraded variant of the Feather RP2350, featuring a pre-soldered AP6404L 8 MB PSRAM chip for managing large data buffers, display framebuffers, and memory-intensive applications directly in mappable RAM. Combined with dual Cortex-M3...

SKU: AF-6335 · MPN: ADA6335

A modern take on the common RGB colour sensor — the OPT4048 provides true CIE XYZ tri-stimulus output so you can match readings directly to standard colour spaces. It also calculates colour temperature (based on CIE) and lux measurements up to 144 kLux, making it suitable for everything from dim ...

SKU: AF-5606

The Adafruit ENS160 is a fully integrated metal-oxide (MOX) gas sensor from ScioSense, designed as a drop-in upgrade for the now-discontinued CCS811. It combines multiple MOX sensing and heating elements on a single chip to provide detailed air quality readings including TVOC (Total Volatile Orga...

SKU: AF-4374

The Adafruit BrainCraft HAT is a Raspberry Pi 4 add-on board designed for machine learning and AI projects at the edge. It combines a display, stereo microphones, audio output, camera connector, user controls, and sensor ports into a single HAT, providing everything needed to build audio and vide...

SKU: AF-4756

The Adafruit LTC4311 Active Terminator solves a common I2C problem: running long cables. Standard I2C is designed for short PCB-level connections, but cable capacitance and resistance degrade signals over distance. The LTC4311 watches the SDA and SCL lines and actively boosts pull-up current, res...
