FIELD TEST

his is the Adafruit Feather M0

Bluefruit LE, an Arduino-compatible

board with Bluetooth Low Energy,

USB connectivity, and battery

charging. It’s the same as the Feather

M0, with the addition of a BLE module.

This enables your project to communicate with your

computer or smartphone, even one running iOS,

without any special certifications.

The board features an nRF51822 chipset from

Nordic, which is capable of easily sending strings

of data wirelessly via a UART RX/TX connection.

Adafruit provides apps for Android and iOS to get you

up-and-running fast. In addition to these basic BLE

functions, the board is capable of a lot more via AT

command sets. You can query the die temperature,

check battery voltage, and more. You can even use

it to simulate a HID keyboard, which allows anyone

with even basic knowledge of electronics to make

interactive projects that control a computer. Be sure

to check out the website for a list of everything this

capable little board can do.

VERDICT

9 / 10

You might think that the FeatherWing format is too

small for a colour TFT display, but you’d be wrong.

This FeatherWing not only features a 160×80 colour

TFT display, but it also has a five-way joystick and two

buttons. This might be my personal favourite add-on

FeatherWing to the Feather ecosystem, especially

whenever I need user feedback in a project.
