data sheet is available here
>>>>>
The X-NUCLEO-IKS4A1 sensor expansion board for STM32 Nucleo boards includes a variety of sensors. These include an IMU with an embedded processing unit, an IMU with an embedded sensor fusion block, a high-precision pressure sensor, and a temperature and humidity sensor. It also features a QR electrode board for touch and swipe detection, a socket for an infrared sensor, and a DL 24 socket for external sensors.

A fatal error occurred: This chip is ESP32-C3, not ESP32-S3. Wrong --chip argument?

This is a comforting error message from the Arduino IDE 2.3.6

Arduino pro micro programmed successfully about 7 years ago using version 1.8.19 of Arduino IDE. Today we tried using the version 2.3.6 and the IDE did not recognize the device.

SSD1306 128 * 32 i2c happily responds and is back in operation.
The board is recognized as 'Arduino Micro'. The silk screen shows 'Pro Micro'.

So an old version of the IDE did the job.
