Vadj: not clear if can work with Vadj of 1.8V
The wiki page shows: Vadj can be 1.8V (please check!) or 2.5V. But it is not clear that this is true. The same wiki page also reads:
- VADJ is connected to
- MCP23017-E/SS (specified supply from 1.8V to 5.5V),
- the ADC AD7997BRUZ-1 (specified for VDD from 2.7 V to 5.5 V),
- and LD2 (which is less bright on Vadj of 1.8V).
EB has a mail where it was told that it has been tested on a FASEC card with Vadj of 1.8V without any problem. But it is not clear if the ADC has been used or not.
Correct wiki page if necessary.
