Features: 1. Onboard ADS1263 chip, low noise, low temperature drift, 10-channel 32-bit (5-channel differential input), 38.4kSPS Max sampling rate2. The chip comes with 24-bit auxiliary , internal , IDAC, 2.5V internal reference voltage, 8 multiplexed GPIO, (32 Max)3. The on-board pin header package input interface can to analog signals, with the -snow sensor interface standard, which is convenient to to various analog sensor modules4. The input interface of the on-board terminal package can be connected to analog signal and analog supply, which is convenient for in various occasions5. The on-board pin header package control interface can access control signals, which is convenient for using devices other than to control this module. On-board three-wire RTD (resistance temperature detector) circuit, by welding 0R resistors, it is convenient to three-wire RTD for measurementSpecification:Resolution: 32 Bitscolor: blueMaterial: PCBNumber of input channels: 10Sampling rate (Max): 38.4 kSPS multiple (Max): 32Interface type: SPIArchitecture: -Input Type: Differential, Single-endedReference Voltage: Internal, ExternalInput voltage range (Max): 2.5V, 5VInput voltage range (Min): -2.5V, 0VProduct size: 65 x 30.5mmPackage Contents:1 x Expansion Board Module1 x RPi copper pillar packageOnly the above package content, other products are not included.Note: Light reflection and different displays may the color of the item in the a little different from the real thing.
