Attach the expansion board to the STEVAL-STWINBX1 kit using the provided flex cable and connectors.
Flash the STWIN.box with the FP-SNSDATALOG2 function pack for data acquisition.
For removal of the flex cable, use tweezers to avoid damage.

Precautions for use

Ensure to consider the following precautions:

Avoid exposure to intense radiant sources as per EN IEC 61000-4-3 standard.
During radiated immunity testing, expect performance degradation of over 2% in voltage and current measurement.

Introduction

The STEVAL-C34KPM1 evaluation kit allows the user to evaluate the performance of the TSC1641, 16-bit, high precision current and power monitor with an MIPI I3C/I2C interface. The board can measure: voltage up to 60 V, a load current up to 10 A delivered power, and temperature based on the dual channel power monitor. The current measurement can be high-side, low-side and bidirectional. Analog filters can be implemented on the board. This expansion kit is compatible with the STWIN.box (STEVAL-STWINBX1), and it is supported by the high speed datalogger function pack (FP-SNS-DATALOG2)

Main component

TSC1641

The TSC1641 is a high precision current, voltage, power, and temperature monitoring analog front-end (AFE). It monitors current into a shunt resistor and load voltage up to 60 V in a synchronized way. The current measurement can be high-side, low- side and bidirectional. The device integrates high precision 16-bit dual channel ADC with a programmable conversion time from 128 μs to 32.7 ms. The digital bus interface is flexible from an I²C/SMbus 1 MHz data rate to an MIPI I3C 12.5 MHz data rate. This allows connectivity to most of the recent STM32 products.

Get started with the board

The STEVAL-C34KPM1 expansion board can be used with the STEVAL-STWINBX1 kit (STWIN.box). The device can be attached to the STWIN.box using the provided flex cable, through the 34-pin connectors available on both platforms.

To plug the flex cable onto the STWIN.box, remove the plastic case cover.

You can then remount the cover, as it leaves enough space for the flex cable.

The easiest way to read data from the STEVAL- C34KPM1 is to flash the STWIN.box with the FP-SNSDATALOG2 function pack. The firmware package provides a ready- to-use, precompiled binary to perform sensor data acquisition.

Note: Be careful when you remove the flex cable as you may damage it. The safest way to remove it is by pulling it next to the connectors using tweezers.

Precautions for use

The board is not immune to the disturbance generated from intense radiant sources, according to EN IEC 61000-4-3. During the radiated immunity testing, the board obtained level B, meaning that the board was not damaged during the test, but showed a performance degradation of over 2% in voltage and current measurement
