PSU section[edit | edit source]
Powering is usually a delicate operation. In Lizard modules this operation has been embedded in the module and therefore power sequencing is self-contained and simplified. Nevertheless, power must be provided from carrier board, and therefore users should be aware of the ranges power supply can assume as well as all other parameters. Apart from backup supply voltage for on-board RTC, one power voltage is required (VIN). Two power schemes may be adopted:
- VIN = 3.3V (Zefeer compatibility)
- VIN in the range 3.6V-6V.
Scheme #1 is supported by default. In case scheme #2 is required, please contact technical support for more details.
