A quad level-shifting buffer IC that excels at converting 3V logic signals up to 5V. Power the 74AHCT125 with 5V and it will cleanly detect 3.3V logic inputs — particularly useful when connecting devices like Teensy 3.x to NeoPixels or other 5V peripherals. To use, apply 5V to VCC, connect GND, ...

SKU: AF-3500

The Adafruit Trinket M0 is a tiny but powerful microcontroller board built around the ATSAMD21E18 32-bit Cortex M0+ processor. It shares the same compact form factor and pinout as the original Trinket, but with a massive upgrade in processing power, memory, and connectivity — including native USB...

SKU: AF-3877

A hex Schmitt-trigger inverter IC that doubles as a handy logic level shifter. The 74AHCT14 provides six independent inverter channels, each with Schmitt-trigger inputs for clean switching on noisy or slow-transitioning signals. Spec'd for 5V operation but works at 3V as well. High-level inputs ...

SKU: AF-5649

The Adafruit QT 3V to 5V Level Booster Breakout lets you connect 3.3 V STEMMA QT / Qwiic devices to sensors and peripherals that require 5 V power or logic. Most modern microcontrollers (ESP32, RP2040, SAMD, micro:bit) run at 3.3 V, but some sensors and modules still need 5 V — this board bridges...

SKU: AF-2010

Note: The Pro Trinket's bit-bang USB technique is a legacy approach that may not work reliably with modern operating systems. For new projects, consider an ItsyBitsy or Metro Mini board with native USB support at a comparable price. The Adafruit Pro Trinket 3V is a compact ATmega328P-based mic...

SKU: AF-5632 · MPN: ADA5632

This breakout makes it much easier to prototype with external QSPI flash on modern microcontroller platforms such as RP2040, ESP32, RT10xx and STM32 designs. It converts a wide 8-SOIC flash package into a breadboard-friendly 0.3" wide DIP format, which is handy when you want to test different fla...

SKU: AF-5636

The Adafruit SPI FLASH Breakout features a W25Q64 chip providing 64 Mbit (8 MByte) of non-volatile flash storage over a standard SPI interface. It's ideal for adding compact, low-power external storage to microcontroller projects — perfect for files, images, fonts, and audio clips when a full SD ...

SKU: AF-5643

The Adafruit SPI FLASH Breakout features a W25Q128 chip providing 128 Mbit (16 MByte) of non-volatile flash storage over a standard SPI interface. It's ideal for adding compact, low-power external storage to microcontroller projects — perfect for files, images, fonts, and audio clips when a full ...

SKU: AF-4718

The Adafruit SPI Non-Volatile FRAM Breakout provides 2 Mbit (256 KBytes) of ferroelectric RAM (FRAM) storage over SPI. FRAM combines the non-volatile retention of flash with the instant read/write speed of SRAM — no page writes, no block erasing, and each byte can be written 10 trillion times wit...

SKU: AF-6318 · MPN: ADA6318

This driver board makes it much easier to control multiple solenoids from a microcontroller over I2C. It uses an MCP23017 GPIO expander so you do not need to dedicate lots of pins just to switch a bank of clicky, inductive loads.Solenoid power connects through the centre terminal blocks, with eac...

SKU: AF-4719

The Adafruit SPI Non-Volatile FRAM Breakout provides 4 Mbit (512 KBytes) of ferroelectric RAM (FRAM) storage over SPI. FRAM combines the non-volatile retention of flash with the instant read/write speed of SRAM — no page writes, no block erasing, and each byte can be written 10 trillion times wit...
