SparkFun Qwiic Shield - Shield with Qwiic connectors for Thing Plus

This expansion board is designed for light and sound, cosplay, and interactive prop projects. It features a ready-made NeoPixel port with a level converter, 3W RGB LED drivers, and a Class D audio amplifier for driving 8Ω or 4Ω speakers. The built-in LIS3DH accelerometer allows for motion, impact, and tilt detection, ideal for dynamic effects. It works with a wide range of Feather boards, allowing you to quickly create advanced projects in a compact format. Adafruit 4145

Module with a GPS receiver based on the MTK3333 system. Dedicated to Feather plates, communicates via the UART interface. Adafruit 3133

This is the FeatherWing OLED: it adds a 128x32 monochrome OLED plus 3 user buttons to any Feather main board. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board take flight. Adafruit 2900

Data logger dedicated to Thing Plus tiles. It allows you to save data on a microSD card with the possibility of reading through the USB port. Supports cards up to 32 GB. SparkFun DEV-19217

FeatherWing Doubler is a shield that allows you to create your own layout based on two or one Feather series. The plate has 256 holes, including designated, common solder points for supply voltages. Adafruit 2890

OLED display with a diagonal of 1.3" and a resolution of 128x64 pixels. Designed for use with Feather series plates. Adafruit 4650

Module with 3-axis accelerometer ADXL343 and precise temperature sensor ADT7410 dedicated to Feather series boards. Equipped with a STEMMA QT connector, it communicates via the I2C interface. Adafruit 4147

This compact development board allows direct connection to 24-pin e-paper displays, ideal for energy-efficient visual projects. Equipped with a 133MHz RP2040 microcontroller, 264KB SRAM, and 8MB Flash, it offers smooth display caching and support for a wide range of peripherals. It features a dedicated SPI display interface, a STEMMA QT connector, a Li-Po charger, USB-C, and a comprehensive GPIO set with PWM, ADC, and I2C, SPI, and UART communication. Adafruit 5727

These add-ons for any Feather board will let you integrate packetized radio (with the RFM69 radio) or LoRa radio (with the RFM9x\'s). These radios are good options for kilometer-range radio, and paired with one of our WiFi, cellular or Bluetooth Feathers, will let you bridge from 433/900 MHz to the Internet or your mobile device. Adafruit 3232

Module with a current and voltage sensor dedicated to Feather boards. Can measure voltage up to 26 V and current up to 3.2 A. Based on INA219 sensor, I2C communication. Adafruit 3650

Data logger dedicated to Feather plates. Equipped with RTC clock, battery slot and micro SD card slot. Adafruit 2922

FeatherWing Proto - Prototyping Add-on For All Feather Boards

Feather board will let you integrate packetized radio (with the RFM69 radio) or LoRa radio (with the RFM9x\'s). These radios are good options for kilometer-range radio, and paired with one of our WiFi, cellular or Bluetooth Feathers, will let you bridge from 433/900MHz to the Internet or your mobile device. Adafruit 3230

Module with monostable relay. It allows you to control high-power elements with a microcontroller. Adafruit 3191

Extension module dedicated to matrix displays with HUB75 interface. Designed for Feather RP2040, M0 and M4 series tiles. Adafruit 3036

This module allows you to add MIDI input and output to your Feather board, utilizing DIN-5 connectors and a built-in 3V optocoupler for secure 3.3V communication. The module also features LEDs to indicate data transmission and optional 3.5mm TRS MIDI sockets for the TRS MIDI A standard. It communicates via a hardware UART set to 31250 baud, allowing for easy integration with Adafruit 4740 MIDI instruments and controllers.
