Possible services:
- Definition or refinement of specifications

- Small and medium series with programming and unit testing
Types of projects already completed:
- Low-power 802.15.4 wireless sensors in a mesh network
- Embedded systems with RTOS

- Adaptations, improvements, corrections of existing designs
You can entrust me with a specific block (e.g., routing) or the entire development up to the functional prototype.
