BQ25185 all-in-one Li-Poly board with 3.3V out 🔋🌞⚡
We had a previous version of this 3.3V buck output board with an MCP73831, but now we've replaced it with a BQ25185, which makes it a little more flexible: Vin can be up to 18V, and solar panels will work, too. There's also a power path and 4.5V regulated output. This charger chip can handle LiFePO4, but for that chip, we might swap the buck for a buck-boost or a boost / LDO to get the solid 3.3V output. Coming soon.
