DIY InkHUD Builds

DIY Presets

Tried-and-tested hardware combinations, with pre-made configurations.

Supported Hardware

Base Device

• Heltec Mesh Node T114
• NRF52 Pro-micro DIY

Display Module

• WeAct Studio 1.54" B&W
• WeAct Studio 2.13" B&W (2025 Revision)
• WeAct Studio 2.9" B&W
• WeAct Studio 4.2" B&W

Firmware

Although configurations for these devices are provided, you will still need to build the Meshtastic firmware.

Building With Visual Studio Code

First, set up the build environment, then:

1. Open the PlatformIO Project Tasks pane

2. Select the environment which matches your node hardware

   • heltec-mesh-node-t114-inkhud
   • nrf52_promicro_diy-inkhud

3. Run the Build task which matches your display model

4. Once build is complete, find the generated .uf2 file at ./pio/build/<environment>/firmware.uf2

Building with Platformio CLI

Execute pio run -e <environment> -t <build task>, where:

<environment>

• heltec-mesh-node-t114-inkhud
• nrf52_promicro_diy-inkhud

<build task>

• build_weact_154
• build_weact_213
• build_weact_290
• build_weact_420

Then find the generated .uf2 file at ./pio/build/<environment>/firmware.uf2

Installation

Install the generated .uf2 file to device using the drag and drop method.

Other Hardware

Using InkHUD on hardware beyond the standard DIY presets will require manual customization of the firmware. No specific support can be given here; only a general overview.

Check for a Display Driver

InkHUD relies on custom display drivers. These are located in /src/graphics/niche/Drivers/EInk/. Choose a display which is already supported, otherwise you will have to write the driver yourself, which requires some specialist knowledge.

Clone and Modify an Existing InkHUD Variant

The general instructions for building with custom hardware apply here. In addition to modifying the variant.h file, you should also modify nicheGraphics.h, which is responsible for InkHUD's per-variant configuration.
