Small PCB for openDTU, supporting small display

Small PCB for openDTU Based on idea/ realization of breakout board 2nd version with much smaller PCB 1st version The PCB has the ESP32 on backside, Display and nRF24l01 on frontside. Dedicated case available in openscad directory Configuration file nodemcuesp32.json available in openDTU, please select "Generic NodeMCU 32 with SSD1306" as profile In case you struggle how to configure openDTU, the documentation can be found here openDTU Display documentation * The PCB is designed to work with ESP32S NodeMCU (38 Pins) e.g. Amazon

OpenDTU wDisplay: common questions

What microcontroller does the OpenDTU wDisplay use?

The OpenDTU wDisplay is built around the ESP32NodeMCU, from the ESP32 family.

How big is the OpenDTU wDisplay PCB?

The OpenDTU wDisplay measures 96 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OpenDTU wDisplay?

4 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the OpenDTU wDisplay design files?

From the SteffMUC/openDTU_wDisplay2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the OpenDTU wDisplay design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the OpenDTU wDisplay without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
