"Adafruit FeatherWing Add-ons For All Feather Boards - Adafruit 2926, The Adafruit FeatherWing Terminal Block Breakout Kits are wider than the standard Feather footprint to accommodate a row of screw-in terminals on either side. All the Feather pins are brought out to the terminal blocks and to rows of pads next to a prototyping area. Adafruit even widened the board a bit further and added on board labels for the major signals such as I2C, SPI, serial and power. Once you have soldered on the kit components your Feather board can be plugged into the female headers and external connections can be made to the terminal blocks. Because the Feather board is raised on the headers its battery connector is still available. As a bonus Adafruit have included a small PCB mount slide switch that will switch the 3.3V regulator on and off. This doesn't affect the BAT battery voltage so it won't affect the FONA Feather boards but it will work with all the other main boards.Supplied as a bare pcb plus terminal blocks, strips of 0.1in. pitch female headers, and a PCB mount switch for you to solder on as required.

"Adafruit 2945 NeoPixel FeatherWing - 4x8 RGB LED Add-on For All Fe..."
"Adafruit FeatherWing Add-ons For All Feather Boards - Adafruit 2945, The Adafruit NeoPixel FeatherWings bring 32 x pixels of individually addressable RGB ultra-bright bling to your Feather project. It's hard to believe that all these NeoPixels can be controlled from a single GPIO and you get 24-bits of colour too. There are rows of solder jumpers on the bottom of each board so that you can select which GPIO is going to do all the hard work. If you are using one of the Feather Huzzah ESP8266 boards (73-5299) then you will need to use pin 15, it's a very simple change. There's an onboard level-shifter to convert this signal to 5V for greater reliability and for the Dout signal to daisychain to other boards. For those times when 32 x LEDs isn't enough.The NeoPixels take their power either from the USB or from the battery power line, whichever has the higher voltage, thanks to a pair of Schottky diodes. This will give you up to 1A of constant current drive and up to 2A peak, more than enough for a colourful light show, but be careful if you're trying to light your lounge.Adafruit have published a driver library to save you the trouble and let you get on with designing eye catching displays. They have a reputation for the quality of their supporting documentation and you will find their Uberguide to NeoPixels and their Best Practices guides invaluable. In particular the Best Practices guide will help you prolong the life of your NeoPixels and avoid common mistakes. Adafruit 2945 NeoPixel FeatherWing - 4x8 RGB LED Add-on For All Feather Boards"

"Adafruit 2928 8-Channel PWM or Servo FeatherWing Add-on For All Fe..."
"Adafruit FeatherWing Add-ons For All Feather Boards - Adafruit 2928, The Adafruit 8-Channel PWM or Servo FeatherWing Add-ons use only the 2 x I2C signals from your Feather microcontroller (MCU) plus power to run 8 x servos or LEDs with 12-bit PWM. They're the same diminutive size as all the Feather main boards and FeatherWings, just right for making compact projects that can stand up to their bigger cousins.Once you send an I2C command to one of these boards, it takes over and maintains the PWM outputs you've set and your MCU can get on with more important things. They are 5V compliant so your 3.3V Feather can safely drive outputs up to 6V which is handy if you want to drive white or blue LEDs with 3.4V or more forward voltages. With 6 x address select pins each you can theoretically stack 62 x of these on a single I2C bus for a total of 992 outputs. Very useful for sending Morse code message to the International Space Station or building that millipede robot you've been dreaming of. The outputs are configurable to operate in either push-pull or open-drain mode.The boards are crammed with the neat little touches that Adafruit do so well, such as reverse polarity protection on the power input, a green power good LED, a spot to add a big capacitor if you need to, 220 Ohm limit resistors on all the outputs and a stackable design so you can have as many outputs as you need.Adafruit have a free tutorial and library for the Arduino Shield version and well documented example code to help get you started.

Because Adafruit has used the smallest components available there's room at one end of the board for a specialist function such as an SD-card holder, Bluetooth LE, packet radio, LoRa, a prototyping area or even WiFi. The Feather main boards feature a USB port for power and programming, a LiPo battery connector, 20 x GPIO pins including 8 x PWM pins and 10 x analogue inputs, and support for serial, I2C and SPI in hardware. Each one has a 3.3V DC regulator which is able to supply up to 500mA peak current. The boards have a 100mA LiPo charging function with a status indicator LED and there's also a general purpose LED for blinking. The Feather boards are about ⅓ x the size of an Arduino UNO and there's even a Reset button. Once you've chosen your processor, select one or more FeatherWing add-on boards and get developing. The range includes development tools such as prototype boards and an over-size board with screw terminal blocks for external wiring.Supplied with an assembled and tested main board plus strips of 01.in. header pins for you to solder on as required. Adafruit supply an extensive free tutorial which contains everything you could need. Adafruit 2829 Feather 32u4 Arduino Compatible Bluefruit LE BLE"
