About the Test 09. With ESP module

Test 09. With ESP module is an open source ESP32 PCB design by henkjannl, published on GitHub under the MIT license. It is a 2-layer board measuring 90 × 54 mm, with 62 components from 41 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N8R2, from the ESP32 family. Other key parts include the UZ1086L-33-TN3-R, EL357N-G and ILI9341_no_touch. By type, the board carries 18 diodes, 12 resistors, 9 capacitors, 7 test points, 5 ICs and 3 connectors.

It belongs with the iot & wireless designs in this gallery.

From the project

Opentherm room thermostat that can be controlled through Telegram, but also locally

I wanted to create a room thermostat that can be controlled remotely ('honey, did you remember to switch off the heating?') but which also remains fully operational if internet connectivity is lost. Therefore it can be controlled through Telegram, but also via the hardware unit if WiFi is down. This is also useful since visitors may not want to use Telegram.
