The board is laid out in the Adafruit Feather format, providing compatibility with dozens of add on boards (FeatherWings).
The specifications are super impressive:
ARM® Cortex M33, 1 MB Flash, 256 kB RAM
Nano SIM and Embedded SIM, LTE Cat-M1, LTE Cat-NB1 aka NB-IoT, Global coverage
And the board layout:
— USB (via FTDI UART Bridge)
— up to 18x General Purpose IO
— up to 6x 12-bit, 200 ksps ADC with EasyDMA
— up to 4x SPI master/slave with EasyDMA (can be mapped to any pin)
— up to 4x I2C master/slave with EasyDMA (can be mapped to any pin; 1 preconfigured for on-board I2C peripherals and default I2C pin headers)
— up to 4x UART (also with CTS/RTS) with EasyDMA (can be mapped to any pin; 1 preconfigured for on-board USB-UART Bridge)
— I2S (Inter-IC Sound Interface) with EasyDMADigital microphone interface (PDM) with EasyDMA (can be mapped to any pin)
— 4x pulse width modulator (PWM) unit with EasyDMA (can be mapped to any pin)
— Serial Wire Debug (SWD) on 6-pin TagConnect footprint on top side plus programming pads on bottom side
The board also has:
Low Power 3-axis accelerometer
General Purpose Button
Battery voltage reading, capable of very low power consumption
We provide Icarus with a free e-sim which has 10MB data to use for 3 months, so you can start testing your prototype immediately (only in supported countries).
Actinius states the board runs @ZephyrIoT OS by default.
The company also states that they are considering a version with a Microchip SAMD processor also onboard. That would open it up to Arduino. (Hint: making a version which was subordinate to say, an Adafruit Feather M4 Express, would allow CircuitPython and communicate, say over SPI, to the Icarus would be AWESOME).
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
