Sensors & Peripherals

This is the inventory + reference list of sensors and peripherals you have on-hand.

Goal:

Collect photos + product links + key specs.
Keep wiring/interface details (I2C/SPI/UART/Analog) visible.
Later, generate reusable firmware blocks (gate-based) on RAK3112 for each item.

How to add a new item

When you send a new sensor/peripheral, include (as available):

I will create (or update) a dedicated page under this section and add it to the catalog below.
