10299 Waveshare

4-Channel 12-bit ADC module 1. 4-Channel: This module has four separate ADC channels, allowing it to measure up to four analog inputs with a single board. 2. 12-Bit Resolution: Each of the four channels can measure a 12-bit resolution at either a Max of 2.048V or 4.096V. 3. SPI Interface: The Waveshare module uses Serial Peripheral Interface (SPI) to communicate with its host microcontroller. 4. Two Reference Voltages: The module has two reference voltages - one at 2.048V and the other at 4.096V. You can select which one you want to use for each channel accordingly. 5. Onboard Power Supply: The module has an onboard voltage regulator to supply power to the ADC, making it relatively simple to get up and running. 6. Over Voltage Protection: The module also provides over voltage protection to help protect against any accidental damage. 7. I2C Communication: This module also includes I2C communication, allowing multiple modules to be connected together with a daisy chain configuration. 8. Low Power Consumption: This module has a low power consumption, allowing it to be used with low power systems. 9. Small Size: The size of this module is around 25mm x 32mm, making it relatively easy to fit it into small projects. 10. Stackable: The module is stackable, allowing multiple modules can be connected together for higher resolution measurements.
