via the JM60 microcontroller’s 12-bit ADC. The exception is the MPXM2102A absolute pressure sensor. This is used for altitude
so it requires a high resolution sampling. It passes through an instrumentation amplifier and then is interfaced via an external
24-bit ADC chipset before communication via SPI to the JM60 MCU. The JM60 interfaces with the LCD screen and processes
inputs by the user for the displayed output.
