3.4.2 Minimalist Carrier Board Power Approach
The minimalist carrier board power approach shows the absolute minimum amount of external
components required for running the Verdin module with a carrier board. The Verdin module can
run directly from any power source between 3.135V and 5.5V. This means that the module can run
directly from a 5V USB power port. The PWR_1V8_MOCI provides up to 250mA output current
from the module to peripherals on the carrier board. This means that for simple applications -
which only feature a few sensors and peripherals on the carrier board - no extra 1.8V buck
converter is needed.
