The Clio is a computation, communications, and power distribution hub designed to trade off electronics vs harness weight in a hub and spoke system. Depending on client needs the Clio can be just a low power data and power switch, or a high power flight computer.
The Clio Series B is based around a STM32H7 and Xilinx Spartan 7 and normally runs FreeRTOS with lwIP integration. It offers 2 Ethernet and 17 serial ports, 9 switched power outputs and a various GPIO with many customizable options.
In order to leverage the Clio Series B, users will be provided with allocortech’s board support and application framework so that they can focus only on the customizations they require.
Clio is outfitted with 2 and 4 wire RS-485, RS-232, 5V TTL, CAN-FD, and 10/100 switched Ethernet in a variety of port mappings. Various serial wire protocols are natively supported, and for ports connected to the FPGA coprocessor many more are possible. Of special note are ports that can be used as Remote Control receiver, PWM, safety termination inputs and PWM outputs.
Clio features 4 independent power inputs which can be fed to 3 independent power distribution busses. One of these busses can also be powered from an internal, adjustable 3.5A power supply for even more flexibility. These distribution busses then feed 9 independently switched and e-Fused power outputs.
Functional safety of the Clio can be assured with a comprehensive set of voltage taps, as well as high and low side current measurements on both the inputs and outputs.
