Morpheus-STM32
About the Morpheus-STM32 PCB
Morpheus-STM32 is an open source PCB design by pscrespo, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 66.4 × 92.5 mm, with 60 components from 37 distinct parts.
Other key parts include the Pololu Driver, LM1117-3.3 and BluePill_STM32F103C. By type, the board carries 13 resistors, 8 capacitors, 6 ICs, 6 connectors, 6 diodes and 3 transistors.
From the project
A small 3D printer controller board for use with a "blue pill" STM32F1 generic board. Inspired on http://reprap.org/wiki/SinapTec
- Follow the KISS Principle - Low cost - Single layer copper board - DIY-able (easy to make via toner transfer) - Only through-hole components - The very basic a printer would need - Keep bed circuit separated/optional (if you are making a PLA only printer without a heated bed, you don't need to populate the bed circuit zone) - Open Source Hardware, made in Open Source Software
