controlled from a STM32F4 Microcontroller dipcoref4,CV1
build for CV1 as UI-Expansion-PCB.
ready for Pick and Place
–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
Building
The Design is optimized for Pick and Place > all SMD Parts are on the Top-PCB
The Rest is Thruhole > easy
now waiting for Presoldered PCBs
