Its unique design allows you to use the Arduino footprint to interface with the huge array of existing Arduino shields, while still using the LCD and buttons. You can add Ethernet, WiFi, motor drivers, even GSM… all with no soldering needed!
Sunlight readable monochrome display with white backlight
20 x GPIO in Arduino footprint (capable of PWM, SPI, I2C, UART, Analog Input)
Support for GSM, LTE, WiFi and Ethernet Arduino shields
2.5v to 16v input range (0.3mA idle)
CR2032 battery holder (Battery not included), or Micro USB (power only)
4 x 3mm mounting holes
4 x buttons
Built in thermometer and battery level sensors
Dimensions: 60mm x 53mm x 15mm (2.4 x 2.1 x 0.6 inches)
Pixl.js can be powered in multiple ways:
Micro USB – the Micro USB connector can easily provide power to your Pixl.js (there is no data connection)
Vin pins – available via the Arduino header, or the separate pin header to the side. You can supply 3v – 16v which is regulated down to 3.3v for Pixl.js. The unpopulated pins to the side are spaces to accommodate a connector for JST PHR-2 Batteries.
CR2032 LiPo battery – you can not use a CR2032 LiPo battery without some minor modifications as the voltage is too high. There is a small solder jumper below the CR2032 holder. Cut the existing connection and solder between the other two pads. This causes the battery to be connected via the voltage regulator. Note: the LiPo will then be connected directly to Vin, and you will be unable to use the USB for power (as it’ll connect to LiPo to 5v).
CR2032 battery backup – the CR2032 can be used as a backup when Vin/USB power is not present. Cut the trace in the solder jumper below the CR2032 holder, and add a surface mount diode to the two pads to the right of it.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
