The Impetus module
The Impetus is an M2 form factor System on Module (SoM) powered by the Sochip/Allwinner S3 SoC, with an ARM Cortex-A7 clocked at 1.2GHz, paired with 1Gbit of DDR3 DRAM. It comes with a Broadcom WiFi a/b/g/n + Bluetooth® interface, MicroSD Card slot, and a host of other interfaces to build upon.
The Impetus’ strong point is its M2 connector, allowing us to quickly test it on a custom board to rapidly prototype and verify specific use cases, without having to design a Linux SBC from scratch.
The first operating system under development is our freely available and customisable Buildroot-based Linux, but we are working on a Debian image and our kernel mainlining effort means that we will be able to build whichever system is required based on mainline Linux 5.11 or later.
The Initium board
The Initium is the development board for the Impetus. It brings out the host of interfaces on the Impetus’ M2 pins to convenient connectors that can be used right away, before development of any custom hardware.
The Initium features a convenient USB-C connector for power and access to an application UART over USB-UART bridge, an Ethernet 10/100 PHY, a USB2 OTG-capable connector, audio out/mic in jacks, convenient diagnostic LEDs and all the M2 signals on a labeled header plus expansion slot.
