Adafruit QT Py SAMD21 Microcontroller Board Products

Description

The Adafruit QT Py SAMD21 microcontroller board breaks out the SAMD21 MCUMicrocontroller Unit on a small thumb-sized board (0.8in x 0.7in). The board includes a USB-C connector for power and programming, STEMMA QTSTEMMA QT ('cutie') connectors are Adafruit's name for 4-pin JST SH connectors with 1.0mm pitch. These connectors were implemented on Adafruit boards to make it easy to plug-n-play various sensors and devices without soldering and wiring. The STEMMA QT (JST SH) are a smaller connector than the STEMMA (JST PH) that do not fit on smaller boards. STEMMA QT is cross-compatible with SparkFun Qwiic connectors. connector for I2CInter-Integrated Circuit. Also referred to as IIC or I²C., reset button, and NeoPixel RGBRed Green Blue LEDLight Emitting Diode. There are also solder pads on the back of the board to add more memory with a 8-Pin SOICSmall Outline Integrated Circuit SPISerial Peripheral Interface Flash chip.
