ID01 UHF RFID Module-RS485 [Discontinued] _MAKE_POWER_PSU Supports AT commands to configure

Supports AT commands to configure BLE

this Gravity: Analog Infrared CO2 Sensor For Arduino (0~5000 ppm) is a high-performance sensor that combines technology of mature infrared absorption gas detection with precision optical circuit design as well as sophisticated circuit design

so you can expect things like I2C and SPI and analog reads to work

It not only helps protect the meter during transport
