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 Heltec WiFi Lora 32 or the corresponding TTGO version. See the 30pin version if you have a DOIT ESP32 DevKitV1, or the Heltec Cube Cell version.
Problem: You have a Heltec WiFi Lora 32 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: Use this board and all typical ports are lined up as pin header plugs/connectors for easy extraction – each including ground, 3.3V and 5V.
Goodies:
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”
