POOM I2C Sensor Scanner

Connect a Qwiic or I2C sensor to POOM and scan the bus to identify device addresses before writing an application.

Run it: connect an I2C peripheral to POOM's I2C pins (see Hardware Reference), then THE MAKER → I2C → A.

Observe: each responding device shows up at its 7-bit address (e.g. 0x68 for many IMUs, 0x3C for a common OLED). No address means a wiring or power problem, not a code problem.
