Minimal-X Adapter Board 30pin

To the -> Shop!

Short description: Makes I2C, SPI, UART and 1-Wire readily accessible as header pins/plug/connector. Used for stand alone implementations where maximal one sensor per port will be used, or in combination with the extension board for many more possibilities.


Hardware: Intended for DOIT ESP32 DevKitV1 or corresponding development boards. See the Minimal-X Board version if you have a Heltec WiFi Lora 32 or the corresponding TTGO.


Problem: You have a DOIT ESP32 DevKitV1 development board and are tired of wiring the I2C, SPI, UART and 1-Wire ports again and again with lose wires making up a birds nest.

Solution: All typical ports are lines up as pin header plugs/connectors for easy extraction  – each including ground, 3.3V and 5V.



1.) You also have the space for components for one voltage divider (through hole resistors).

2.) Get further sensor connectors by plugging it into the extension board “Minimal-X Extension Board”
