# LEA Control Board



![](documentation/figures/lcb_all_pcbs_labeled.png)    



The LEA Control Board (LCB) is a construction kit to provide power electronic converters with a control board.



The basic module is the control board (LCB-CCB) itself. It contains a powerful dual-core processor, error latches and various predefined low-pass filters to respond to input signals. An XDS100v2 debugger is directly integrated on the board. 



The docking board (LCB-CDB) is suitable for initial operation. This contains various input options (switches, buttons, potentiometers) as well as LEDs for output.



The external hardware monitor (LCB-CHW) is for viewing internal counter variables on the oscilloscope and is mainly used for troubleshooting the control board in the overall system (control board + power converter).

The pin board (LCB-CPB) is for in-circuit signal measurments by an external scope on certain pins.

The test board (LCB-CTB) was developed to check all pins, PWM signals, ADCs and DACs for functionality after a new board has been completed (end of line test).



## PCB overview

This is the main repository of the LEA Control Board (LCB) project. Due to correct PCB versioning, every single PCB is in its own repository.

 * [LCB-CDB-01_Dock_Board](https://github.com/upb-lea/LCB-CDB-01_Dock_Board)

 * [LCB-CHW-01_Hardware_Monitor](https://github.com/upb-lea/LCB-CHW-01_Hardware_Monitor)

 * [LCB-ADA-01_Adapter_Board](https://github.com/upb-lea/LCB-ADA-01_Adapter_Board)

 * [LCB-CPB-01_Pin_Board](https://github.com/upb-lea/LCB-CPB-01_Pin_Board)

 * [LCB-CTB-01_Test_Board](https://github.com/upb-lea/LCB-CTB-01_Test_Board)

 * [LCB-CBB-01_Bus_Board](https://github.com/upb-lea/LCB-CBB-01_Bus_Board)



Symbols, footprints and 3D-models can be found in the [LEA KiCad Library](https://github.com/upb-lea/LEA_KiCad_Library).



Due initially wrong selected comparators (no rail-to-rail), the comparator adapter board [LCB-ADA-01](https://github.com/upb-lea/LCB-ADA-01_Adapter_Board) was introduced to replace the comparator.



## PCB versioning

Example `LCB-CCB-01-1.0.5`:

 * First three letters `LCB`: Parent project name `LEA Control Board`

 * Second three letters `CCB`: PCB name `Control Board`

 * Number `01`: PCB size. For future use in case of several PCB sizes

 * First version number `1`: Major version, increases for incompatible changes

 * Second number `0`: PCB release, increases for improved layouts

 * Third number `5`: Schematic version, increases for component changes, but no layout changes



## Kicad Options

To open the LEA Control Board files, [KiCad 8](https://www.kicad.org/) needs to be used. Make sure that you run the latest version of KiCad.



### Downloading this project and folder structure

To use this project, LEA KiCad symbols, footprints and 3D-models need to be included. Note, that both folders need to be in the same direction.



Clone the symbols, footprints and 3D-models:

```

git clone https://github.com/upb-lea/LEA_KiCad_Library.git

```



Clone this project:

```

https://github.com/upb-lea/LCB-CCB-01_LEA_Control_Board.git

```

If you are downloading the `.zip`-files manually, unpack them in the same direction.



### Symbol library and footprint libary

The libraries are included by default, if the above mentioned folder structure was considered. Open Kicad, load one of the projects and see the libraries:

 * `symbol editor` -> Search for `LEA_Symbol_Library`

 * `footprint editor` -> Search for `LEA_Footprint_Library`



### Set environment variable for 3D models:

Please refer to [this section](https://github.com/upb-lea/LEA_KiCad_Library#set-environment-variable-for-3d-models).



## Software

Various software examples using the LEA Control Board is available and can be found [in this repository](https://github.com/upb-lea/LCB-Software). There are examples for using the hardware monitor, SPI, UART and many others.
