Measurement board
This section introduces the OhmPi measurement boards. Starting from this year, it has been possible to use any measurement board with the latest OhmPi code. Consequently, the OhmPi group provides a variety of board options tailored to your technical needs (e.g., laboratory measurement, field measurement), budget, and electronic skills.
The characteristics of each measurement board are described in the following table:
