## Adding your own Hardware
The build system is modular. Adding a new board variant for an already supported architecture is straigtforward.
### Building for your own DIY hardware or mod that you don't want to distribute
1. go to the `variants` folder in the Meshtastic-device sourcecode and make a new directory for your hardware, let's call it `m5stack_core` and copy an existing configuration you wanna modify
```shell
cd variants; mkdir m5stack_core
cp ../heltec_v1/* m5stack_core
cd m5stack_core
```
2. modify the `platformio.ini` *in this subdirectory* from the canonical define of the hardware variant (`HELTEC_V1` in this case) to `PRIVATE_HW` and make the `-I` on the `build_flags` point to the newly created dir.
```shell
[env:m5stack-core]
extends = esp32_base
board = m5stack-core-esp32
monitor_filters = esp32_exception_decoder
build_flags =
${esp32_base.build_flags} -D PRIVATE_HW -I variants/m5stack_core
lib_deps =
${esp32_base.lib_deps}
```
3. edit the `variant.h` file *in this subdirectory* to reflect the defines and configurations for your board. The example is very well commented.
3. build, run and debug until you are satisfied with the result.
### Adding a new off-the-shelf or DIY hardware that you want to distribute (e.g. add a new canon board)
1. do all of the above until your hardware runs fine
2. [Send in a proposal to add a new board](https://github.com/meshtastic/Meshtastic-device/issues/new?assignees=&labels=enhancement%2Ctriage&template=New+Board.yml&title=%5BBoard%5D%3A+)
3. if approved, go to (https://github.com/meshtastic/Meshtastic-protobufs) and send a Pull Request for the mesh.proto file, adding your board to the HardwareModel enum.
4. change your define in `platformio.ini` from `PRIVATE_HW` to `YOUR_BOARD`. Adjust any macro guards in the code you need to support your board.
5. add your board identifier to `configuration.h` on the Meshtastic-device repo and send in that Pull Request too.
6. wait for the Pulls to be merged back into Master.
7. profit :-)
