ESCC
About the ESCC PCB
ESCC is an open source STM32 PCB design by berkeleyauv, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 36 × 40 mm, with 28 components from 17 distinct parts.
Its main chip is the STM32F072CBUx, from the STM32 family. Other key parts include the AZ1117-3.3, ATA6561, BESC and ACS725xLCTR-30AB. By type, the board carries 15 capacitors, 5 ICs, 3 connectors, 2 switches, 2 resistors and 1 diode.
It belongs with the robotics & motion designs in this gallery.

ESCC: common questions
What microcontroller does the ESCC use?
The ESCC is built around the STM32F072CBUx, from the STM32 family.
How big is the ESCC PCB?
The ESCC measures 36 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESCC?
28 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the ESCC design files?
From the berkeleyauv/RoboSub_HW repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ESCC design in my own project?
Yes, under the terms of its GPL-3.0 license, which berkeleyauv chose for the repository.
Can I test firmware for the ESCC without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
