The module also features 16MB of flash memory

Its an Adafruit Feather 32u4 with a FONA800 module

This allows additional IO to be connected to the board and the state of these can then be read or controlled by the Pico

when using the board at currents up to 6A the chips will barely become noticeably warm

Gravity: NH3 Sensor (Calibrated) - I2C & UART Shipping:1 day The module also features 16MBThis is a sensor that detects ammonia concentration and supports three output modes: analog, I2C, and UART. The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of ammonia in the environment. Can be widely used in the detection of ammonia in industrial and environmental protection fields. The probe adopts the electrochemical principle, has the characteristics of strong anti interference ability, high
