Build the instrument. Understand the reading.

Configure and verify the input range first. Start with a bounded low-voltage bench signal; no sensor calibration or measurement accuracy is promised.

Before choosing itUse the manual’s SPI pin map at 3.3V and explicitly configure reference, gain, channel and conversion timing. The power-up gain is 128, with a narrow input range. Bound the analog stimulus to the configured range and common-mode limits before connecting it.

Inputs

4 differential / 8 pseudo-differential

Digital interface

SPI / 6-pin Pmod

24-bit resolution is not guaranteed system accuracy or 24 noise-free bits. Settling, reference, gain and wiring matter. Header7F cannot read ADC samples or validate the analog circuit; use WaveForms and your own acquisition code for measurements.

Use ambient, non-condensing conditions within the manual. The board’s existing display and LEDs can report the result without another display module.

Before choosing itFollow the HYGRO reference manual’s SDA/SCL and power pin mapping. Use 3.3V power and pull-ups for Basys3, common ground, a correctly oriented port and controller logic that waits for conversion completion. Check the bus pull-up network before adding another I2C device.

Resolution

Up to14 bits

Host interface

I2C / Pmod pass-through

This measures local ambient conditions at the module. It does not measure component junction temperature or certify storage conditions. Header7F does not read the sensor, decode its I2C traffic or verify its accuracy.

One170-point breadboard is already included. This selection does not list another breadboard; your chosen test-point wiring still has to be built and checked.

Before choosing itCheck the module schematic, pin orientation and jumper blocks before connection. Plan accessible male header points for the AD3’s female flywires using its included headers, with power removed. The prototyping area needs appropriate wiring or soldering for your chosen route.

With Header7FPreserve the actual wiring map →

This is a passive prototype carrier, not an active signal adapter or automatic wiring map. A fitted breadboard does not connect itself to every Pmod signal. Header7F cannot verify the connections, shorts, pull-ups or voltage levels.

This 3.3V I2C module needs the separately selected Qwiic cable kit and your own controller logic. No soldering is needed at the Twist when its connector is used.

Before choosing itThe Twist’s Qwiic connector does not mate directly to Pmod. Use the selected cable kit’s header or breadboard lead, map3.3V/GND/SDA/SCL explicitly, and implement its register protocol in your FPGA design. Check I2C pull-ups and address conflicts; default address0x3F.

This is an encoder input, not a motor control, analog potentiometer or protection circuit. SparkFun’s Arduino examples explain the device protocol; they are not drop-in Basys3 RTL. Header7F does not read or configure the knob.

One complete KIT-15081 is selected, quantity1. It includes all 10 leads; none is sold again as a separate item in this bundle.

Before choosing itChoose the kit’s female-jumper lead for suitable male test points or its male breadboard lead for a checked female header/breadboard route. Match black GND, red 3.3V, blue SDA and yellow SCL to the actual Pmod pinout; the Qwiic end alone is polarized.

Lengths in kit

50–500mm

With Header7FKeep connector and pin mapping explicit →

A Qwiic cable is passive and does not translate voltage or rearrange the Pmod pinout. The kit includes 10 leads as one product; buy one kit and do not add its individual leads as separate bundle products. Header7F does not test cable continuity.

One black 4ft cable is selected. It serves Basys3; the measurement instrument’s included USB-C lead stays with that instrument.

Before choosing itAn owned computer needs a suitable USB-A port. Connect the Micro-B end to Basys3’s PROG/J4 port, use the board’s documented USB power setting and confirm board detection in AMD/Digilent tools. The AD3 uses its own included USB-C cable.

Function

With Header7FKeep a known-good programming baseline →

This passive cable does not add a PCIe interface or guarantee programming, current capacity for every loaded design or a working USB port. Header7F does not enumerate USB devices, inspect cable wiring or program the board.
