M5Stack launches compact Kmeter Isolation Unit

Mar 11, 2023 — by Giorgio Mendoza 364 views

M5Stack launched this month a compact K-type thermocouple sensor unit based on the STM32F030 microcontroller. This device is equipped with a 14-bit thermocouple sensor allowing readings from 200°C to 1350°C and ±2°C accuracy.

As described above, this embedded module features the following 32-bit STM32F030 low-power microcontroller:


  • STM32F030 — Arm Cortex-M0 (up to 48MHz); 64K Flash, 4K SRAM

The product page specifies that the KmeterISO Unit can receive firmware updates via I2C interface. Additionally, the module features a CA-IS3641HW chip to “isolate input and output signals to improve stability, safety, and reliability.”

There are a couple of Arduino sketches and UIFlow (Block programming) examples for reference that can be found under the Examples section and the M5Stack GitHub repository.

M5Stack has also recently launched a 2D/1D Barcode Scanner Kit compatible with their ESP32-based ATOM Lite module. 

Lastly, the company mentioned on Twitter that they have restocked their M5stick T-Lite Thermal Camera Dev Kit that was introduced earlier this year.
