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).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
