Armadeus single circuit board
Integration board
The Armadeus board has two big connectors (Hirose type) and need to be plugged on a main board through these two connectors to communicate with the outside world, and more simply, with electrical power. Armadeus developed several development and test boards. They include lots of input/output capabilities, power management, and so on.
For our goal, we need to develop a new main board, with a reduced size and weight compared to the Armadeus' development board, and with only the needed external connectors and components. On this page, we make the list of those needed connectors and design constraints.
Real-time clock
The RTC device is used to keep track of the time in case of power interruption or reboot. The DevFull board from Armadeus embeds one, the Maxim DS1374. It uses the I²C bus and has an internal temperature-compensated oscillator. Datasheet is uploaded here.
