Is the schematic correct in that the voltage regulator is driven by VCC from the mini and not VIN (or “RAW”)? That seems like a colossal mistake, since after the drop-out voltage many GPS’s will be right at their lower voltage limits.
The voltage regulator is driven by VCC. I did a quick test on my board with a 70mA load, and with VCC=3.296V, the LDO resulted with a VOUT=3.267V. The GPS recommended for this board is the GP-375, which has a supply voltage range of 3.1-5.5V.
Can I connect it with “Seeeduino Lotus V1.1 - ATMega328 Board with Grove Interface” ?
