Technical Specification
...
To allow for maximum flexibility in development and testing (and unknown satellite provider) the V1R1 is designed for an input voltage of 5-18V, at 6A. Supplied with the prototype is a 12V, 4A, power supply for desktop use but we can solder on a connector for drone/balloon testing. The input voltage is connected to a switch-mode power supply module for maximum efficiency and then split into four different power rail for the image sensor and FGPA. The PicoZed board requires 5V, 3.3V and 1.8V and the image sensor 2.0V, 3.0V and 3.3V.
The main SMPS can be controlled through the external connector and shut of power to the entire connector. The four power rails will turn on in sequence after the PicoZed power supplies have turned on using the "Power Good" functionality of the regulators. When everything is up and running the microcontroller can check the power rails for the image sensor by reading pin xx.
