# Kirdy Adapter
|
|
Kirdy Adapter is a Butterfly Laser Diode Mount to be used with [Kirdy](https://git.m-labs.hk/sinara-hw/kirdy) mainboard.
|
|
|
|
## Reproducible Project Outputs with Nix
|
|
User can run the following commands to export all the project output including Gerber & Drill files, Bill of Materials file, Schematics PDF and Step 3D model.
|
|
- `nix build .#LD_adapter_copper_plate`
|
|
- `nix build .#LD_adapter_type_1_PCB`
|
|
- `nix build .#LD_adapter_type_2_PCB`
|
|
|
|
## Development Environment
|
|
User can fetch the correct KiCad Version used in the project by running the following command.
|
|
- `nix develop`
|
|
|
|
## Laser Diode Adapter Type 1
|
|
User can configure the following features by populating the corresponding jumper resistors:
|
|
- Pinout of the laser mount
|
|
- Bypass or use the Bias-T Network for injecting RF Modulation into the laser diode
|
|
