Today a very pleasant event happened for us.
The first Epoxy Souvenir Geiger counter #GGreg20_ES has been ordered via @tindie by our user and is getting ready to go to California, USA.
Thank you, Mark! We really appreciate and feel your support for Ukraine. Image We will continue to write about these charitable activities. We also plan to create a dedicated page on our website with information and reports about this project.
As a reminder, the GGreg20_ES project helps to clear the market of non-working Geiger tubes and donates half of the

Application of I2CHUB_V1 – I2C bus interface splitter 🧵
Description of the problem
We have a main system controller and several devices with an I2C interface that need to be connected to it. The figure shows an approximate classic set of modules that may need to be connected to the main controller (MCU).
Most microcontrollers (MCUs) are miniature devices and have a very limited budget for free I / O ports. Typically, on Arduino / ESP8266 / ESP32 / STM32 controllers, only one interface can be reserved for the I2C bus (even if there are two) – two GPIO
