Adafruit QT 3V to 5V Level Booster Breakout - STEMMA QT / Qwiic
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...
Adafruit QT 5V to 3V Shifter Breakout - STEMMA QT / Qwiic
The Adafruit QT 5V to 3V Shifter Breakout lets you safely connect 3.3 V STEMMA QT / Qwiic sensors to 5 V microcontrollers like the Arduino Uno. Many I2C sensors and Qwiic-compatible devices are not 5 V safe — connecting them directly to a 5 V board risks damage. This breakout handles the voltage ...
Adafruit ANO Rotary Navigation Encoder to I2C Stemma QT Adapter
This STEMMA QT adapter makes the ANO rotary navigation encoder easy to use over I2C — no GPIO-heavy wiring needed. An on-board microcontroller running Adafruit's seesaw firmware tracks all rotary pulses and button presses, saving incremental values for querying at any time over I2C. Just plug in ...
Adafruit DS2482S-800 8 Channel I2C to 1-Wire Bus Adapter
·
The Adafruit DS2482S-800 is an 8-channel I2C-to-1-Wire bus adapter on a STEMMA QT breakout board. It allows any I2C-capable microcontroller or single-board computer to communicate with 1-Wire devices — most commonly DS18B20 temperature sensors — without needing to bit-bang the 1-Wire protocol. T...
SparkFun Edge Development Board - Apollo3 Blue
Edge computing is here! You've probably heard of this latest entry to the long lineage of tech buzzwords like "IoT," "LoRa," and "cloud" before it, but what is the edge and why does it matter? The cloud is impressively powerful but all-the-time connection requires power and connectivity that m...

Adafruit QT Py ESP32-S2 WiFi Dev Board with uFL Antenna Port
·
The Adafruit QT Py ESP32-S2 with uFL Antenna Port is the extended-range version of the QT Py ESP32-S2. Instead of an on-board antenna, it features a uFL connector so you can attach any 2.4 GHz Wi-Fi antenna for significantly better range — ideal for projects where the board is enclosed in a metal...
Adafruit ESP32 Feather V2 w.FL Antenna - 8MB Flash + 2 MB PSRAM
·
The Adafruit ESP32 Feather V2 with w.FL Antenna is identical to the standard ESP32 Feather V2 but replaces the PCB trace antenna with a w.FL (MHF3/IPEX3) connector for attaching an external antenna. This makes it ideal for use inside enclosures or when you need improved range from a larger dipole...
SparkFun MicroMod GNSS Function Board - ZED-F9P
With GNSS you are able to know where you are, where you're going, and how to get there anywhere on Earth within 30 seconds. This means the higher the accuracy the better! GNSS Real Time Kinematics (RTK) has mastered dialing in the accuracy of their GNSS modules to just millimeters. The SparkFun M...
