If the board is plugged in but still showing that its disconnected, try a different USB cable. Some cables only provide power with no communication. All 5 GPIO pins are available and are not shared with USB - so you can use them for whatever you like! Only Adafruit Express boards and the SAMD21 non-Express boards ship with the UF2 bootloader installed. The Feather M0 Basic, Feather M0 Adalogger, and similar boards use a regular Arduino-compatible bootloader, which does not show a boardnameBOOT drive. MakeCode Native hardware SPI, I2C and Serial available on two pads so you can connect to any I2C or Serial device with true hardware support (no annoying bit-banging). You can have either one SPI device or both I2C and Serial.

Take a look at alternative solder points to get you out of the sh*t if you do rip something off the board You'll need to solder up your NeoPixels first. Verify your connection is on the DATA INPUT or DIN side. Plugging into the DATA OUT or DOUT side is a common mistake! The connections are labeled and some formats have arrows to indicate the direction the data must flow.DotStars use two wires, unlike NeoPixel's one wire. They're very similar but you can write to DotStars much faster with hardware SPI and they have a faster PWM cycle so they are better for light painting. Three pins can also be used ashardware capacitive touch sensorswith no additional components required The Adafruit Trinket M0 may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power. Adafruit designed a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s one of the lowest-cost CircuitPython programmable boards! This is the 3.3V OUTPUT pad from the voltage regulator. It can provide up to 500mA at a steady 3.3V. Good for sensors or small LEDs or other 3V devices. NeoPixels can be driven by any pin. We've chosen A1. To set the pin, assign the variable pixel_pin to the pin you'd like to use, in our case board.A1.

On Trinket M0, Feather M0 Express, Feather M4 Express, ItsyBitsy M0 Express and ItsyBitsy M4 Express the USB or BAT pins will give you direct power from the USB port or battery. As of March 26, 2021 - We've upgraded this kit from a Trinket to Trinket M0 - which means you can now program your goggles in Circuit Python as well as Arduino! Adafruit SAMD21 (M0) and SAMD51 (M4) boards feature an improved bootloader that makes it easier than ever to flash different code onto the microcontroller. This bootloader makes it easy to switch between Microsoft MakeCode, CircuitPython and Arduino. RGB DotStar LED - Instead of an always-on green LED we provide a full RGB LED. You can set it to any color in the rainbow. It will also help you know when the bootloader is running (it will turn green) or if it failed to initialize USB when connected to a computer (it will turn red). By default after you boot up the Trinket M0 it will turn a lovely violet color. ON LED - this LED lets you know when the Trinket is powered up, it will shine green whenever the 3.3V regulator is working.In general, you shouldn't have to update the bootloader! If you do think you're having bootloader related issues, please post in the forums or discord.

The first step to loading new code onto your board is triggering the bootloader. It is easily done by double tapping the reset button. Once the bootloader is active you will see the small red LED fade in and out and a new drive will appear on your computer with a name ending in BOOT. For example, feathers show up as FEATHERBOOT, while the new CircuitPlayground shows up as CPLAYBOOT, Trinket M0 will show up as TRINKETBOOT, and Gemma M0 will show up as GEMMABOOT Red #13 LED - this LED does double duty. Its connected with a series resistor to the digital #13 GPIO pin. It pulses nicely when the Trinket is in bootloader mode, and its also handy for when you want an indicator LED. On Gemma M0 and Circuit Playground Express this is the Vout pad - that pad has direct power from USB or the battery, depending on which is higher voltage. First, we assign some variables for later use. We create three arrays assigned to variables: keypress_pins, key_pin_array, and keys_pressed. The first is the pins we're going to use. The second is empty because we're going to fill it later. The third is what we would like our "keyboard" to output - in this case the letter "A" and the phrase, "Hello world!". We create our last variable assigned to control_key which allows us to later apply the shift key to our keypress. We'll be using two keypresses, but you can have up to six keypresses at once. CircuitPython-compatible microcontrollers show up as a CIRCUITPY drive when plugged into your computer, allowing you to edit code directly on the board. Perhaps you've wondered whether or not you can write data from CircuitPython directly to the board to act as a data logger. The answer is yes!


So, in your TRINKETBOOT drive, you should have CURRENT.UF2, INDEX and INFO_UF2.TXT. Not in folders, just dumped to the root of the TRINKETBOOT drive. Once started, CircuitPython will blink a pattern every 5 seconds when no user code is running to indicate why the code stopped: If you run RGB code on RGBW NeoPixels, approximately 3/4 of the LEDs will light up and the LEDs will be the incorrect color even though they may appear to be changing. This is because NeoPixels require a piece of information for each available color (red, green, blue and possibly white). We gave the M0 pads the exact same names as the original Trinket so all your existing Arduino code will work exactly the same as-is without changes
