About the IbScaleFeederLite PCB
IbScaleFeederLite is an open source STM32 PCB design by ibScale, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 51.6 × 89 mm, with 74 components from 42 distinct parts.
Its main chip is the STM32F031C6Tx, from the STM32 family. Other key parts include the DRV8837, THVD1400D, TPS563300 and AMS1117-3.3. By type, the board carries 25 capacitors, 25 resistors, 8 diodes, 6 ICs, 3 connectors and 3 switches.
It belongs with the robotics & motion designs in this gallery.
From the project
ibScale Lite Feeder for the LumenPNP
ibScaleFeederLite is an updated version of the Opulo LumenPNP Rev 12 Feeder motherboard with several enhancements.
A Texas Instruments TPS563300 with MLCC capacitors has replaced the original design. The input capacitance has been reduced to 10uF to help prevent arcing during insertion. The reduced capacitance also helps mitigate the excessive bus capacitance start-up issue. A 0.75A PPTC fuse (F1) and diode (D1) have also been added to provide over-current and reverse-current protection.

IbScaleFeederLite: common questions
What microcontroller does the IbScaleFeederLite use?
The IbScaleFeederLite is built around the STM32F031C6Tx, from the STM32 family.
How big is the IbScaleFeederLite PCB?
The IbScaleFeederLite measures 51.6 × 89 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the IbScaleFeederLite?
74 components, from 42 distinct parts. The full bill of materials is listed on this page.
Where can I download the IbScaleFeederLite design files?
