Max Vin voltage

Postby traviswatson » Sat Feb 16, 2019 11:33 pm

If I'm reading correctly, the product page says the max Vin is 12V: https://www.ezsbc.com/index.php/products/wifi01-33.html

Based on the schematic, that seems to be due to the HT7333A's 12V maximum limit. Is that where the limit comes from? I'm asking because I have an application with voltage closer to 14V, and I'm guessing I'm going to need an additional regulator.

Thanks!

Yes, the regulator is the limiting device. However, for higher voltages heat dissipation will enter into the picture as well.
