LORDWORLD ADS1263 10-Ch 32-Bit ADC HAT Development Board

Precision ADC HAT for Raspberry Pi and Jetson Nano

The LORDWORLD ADS1263 board adds a 10-channel 32-bit analogue-to-digital converter to Raspberry Pi series and Jetson Nano platforms. It uses the ADS1263 chip for low noise and low temperature drift with a maximum sampling rate of 38.4 kSPS. An embedded 24-bit auxiliary ADC and programmable gain up to 32 times extend measurement flexibility. The board targets developers who need high-resolution data acquisition for sensors or instrumentation.

Header and terminal interfaces for sensor

An onboard AD header matches the Waveshare sensor pinout for direct module connection while a screw terminal block accepts generic analogue signals and power. A separate control header allows the module to be driven by hosts other than the Raspberry Pi. Eight multiplexed GPIO pins provide additional digital I/O. Builds requiring wireless connectivity or on-board signal conditioning beyond the provided PGA must add those functions externally.

Low-drift operation with internal 2.5 V reference

The ADS1263 delivers low temperature drift and low noise using a 2.5 V internal reference voltage and an internal test signal for verification. A three-wire RTD circuit can be enabled by soldering a 0R resistor for precision temperature sensing. IDAC current sources support resistive sensor excitation. The board draws power from the host platform and adds minimal thermal load in normal use.
