====== LRE5-LCD2 ======
{{:phatline:LRE5-LCD2-Proto-CV1.jpg?500|}}\\
{{:phatline:LRE5-LCD2-3D-Top.png?500|}}\\

**  * 5 Encoders\\
  * 5 Ledrings\\
  * 5 ENC-Switchs\\
  * 5 3LEDS for ENC-Switches\\
  * 1 Shift-Switch\\
  * 2 1306 7Pin- OLED-LCDs**\\
controlled from a STM32F4 Microcontroller [[dipcoref4]],[[CV1]]\\
build for CV1 as UI-Expansion-PCB.\\

ready for Pick and Place\\
{{:phatline:LRE5-LCD2-3D-Buttom.png?500|}}\\
--all Parts except the ULN-Driver-ICs are on the Top-Side, and are presoldered..\\


====== Hardware Requirements ======
  * [[CV1]] or other MIOS32 Cores\\
  * Soldering Iron - with a Dip that can Handle Thruhole-Parts, solder Paste...\\
  * dont forget the Micromatch connectors, and Ribbon cables\\

====== Shematic ======
{{:phatline:LRE5-LCD2-Shematic.pdf?800|}}\\
{{:phatline:LRE5-LCD2-Shematic.png?800|}}\\

====== Building ======
The Design is optimized for Pick and Place > allmost all SMD Parts are on the Top-PCB\\
The Rest is Thruhole  > easy, the ULN Driver are SMD and has to be handsolderd\\

now waiting for Presoldered PCBs\\

10 assambled pick and place PCBs costs 60€ in 2021... so one PCB costs arround 6€\\
but we have to add the other parts wich costs 47€ incl taxes incl shipping in 2023.\\
a big cost is the frontplate which cost 20€... but if you panalize the frontpanel and order more off it you could reduce this costs massive!\\
so 47+6€= 53€ for one LRE5-LCD2-PCB. exclusive off this calculation are Knops for the Encoders.\\

Also you will need one ultrabright LED to illuminate the Matias Switch, the mounting at the moment is a bit diy (hot glue gun)...\\

====== Frontpanel======
{{:phatline:LRE-OLED-BAR2-Frontpanel-BILD.jpg?700|}}\\
I made a DXF File which you can send to [[https://www.formulor.de/|Formulor in Germany]]\\

Here a DXF with one Frontplate, ready to upload to Formulor:\\
I payed 20€ incl taxes and sipping from Germany to Austria\\

{{:phatline:Formulor-P1-1xLRE5LCD2.dxf.zip?700|}}\\

**Recommend Material from Formulor:**\\
3mm Acrylglas GS 181x181mm, mittelgrau transparent(7C83)\\
\\

If you plan to build a MSQ-CC-LRE wit your LRE5LCD2, then you may save money by use this panalized DXF, where 2x LRE5LCD Panels + 2x MSQ-CC-LRE Panels are placed:\\
{{:phatline:FP-LRE-OLED-2X-EURO-FORMULAR-2xLRE5LCD2.zip?700|}} ready to upload to Formulor:\\
I payed 45€ incl taxes and sipping from Germany to Austria\\

**Recommend Material from Formulor:**\\
3mm Acrylglas GS 384x384mm, mittelgrau transparent(7C83)\\



===== PART Locations=====

====== To Do ======
making Revision 2, because in 1 the Transistor-Array-Fottprint is wrong and had to bridged\\
{{:phatline:LRE5-LCD2-Proto-Bridges.jpg?500|}}\\

====== Community users working on it ======
  * **[[Phatline]]** =  PCB & Shematic, UI-Programming, Documentation...\\
