Thing Plus Dual-Port Logging Shield - data logger on a microSD card

Module with monostable relay. It allows you to control high-power elements with a microcontroller. Adafruit 2895

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

DS3231 Precision RTC FeatherWing adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO) to any Feather main board. Adafruit 3028

FeatherWing Proto - Prototyping Add-on For All Feather Boards

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

Cap for use with shallow Feather series, with radio module RFM95W 900MHz. It offers a range of up to 2 kilometers (the range can be increased by using an external antenna). It has a SPI interface. Adafruit 3231

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

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

This module enables the Feather series range to be expanded with 8 12-bit PWM outputs that can be used, for example, to control servos or LED diodes. Adafruit 2928

The Qwiic connector overlay provides an easy-to-install way to add Qwiic connectors to Thing Plus and Feather boards. Communication takes place via the I2C interface. Sparkfun DEV-16790

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

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

A module that allows you to create your own layout based on the Feather tile. Equipped with prototype holes and a set of screw connectors with pins out. Adafruit 2926

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

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

Gamepad module (game controller) with joystick and buttons. Designed for Feather tiles. Adafruit 3632
