What the team does:

Implement low-level drivers for ARM-based MCUs and external chips on a real-time operating system or bare-metal environment
Implement satellite subsystems (battery, sun sensor, reaction wheel, ...)
Collaborate with the hardware/electronics team to ensure a smooth handover and bring-up of the boards
Interface with the Mission and Payload software team to provide low level features (communication interface, non-volatile memories, ...)
Assist with on-orbit flight operations
