The limited mass available to Beagle 2 means that whenever possible the electronic systems have been gathered together so that common functions are not duplicated and connections are short. There is no space for a discrete electronics box. Instead, five circuit boards, of a far from standard shape, are mounted directly onto the lander base.
For thermal reasons, the electronics' boards and battery are situated in combination, one above the other. Extensive use of a 32-bit processor is made as software is obviously lighter than logic circuits and more flexible. The only way that Beagle 2 can achieve its mass goals is by having no redundancy in its electronics whilst relying on a robust and failure-tolerant design.

The "Common Electronics" provide the lander with power management and conditioning, power converters, the central processor, descent electronics, pyrotechnic supplies, motor drives, data handling and experiment interfaces.
