Before you buy
Two things decide whether a board works with what you already own. Address first — every device on a bus needs its own, and the same few keep recurring, so check the address list and the clashes that actually bite before ordering a second sensor. Voltage second — a 3.3 V-only part on a 5 V host needs level shifting, and the compatibility checker answers that per connector ecosystem.
Not sure i2c is even the right bus for the job? i2c vs SPI is the usual decision, and all three compared if you're starting from scratch.
