About the STM32MP1 TestBoard RevB PCB

STM32MP1 TestBoard RevB is an open source STM32 PCB design by cracked-machine, published on GitHub under the MIT license. It is a board measuring 73.7 × 80 mm, with 109 components from 41 distinct parts.

Its main chip is the STM32MP157xAB, from the STM32 family. Other key parts include the MT41K256M16TW-107, SE8233X2, TPS54202DDC and SiP3250x. By type, the board carries 51 capacitors, 30 resistors, 13 connectors, 6 ICs, 4 diodes and 2 crystals.

It belongs with the dev boards & breakouts and power & battery designs in this gallery.

From the project

RevB breakout board for STM32MP1 (Dual A7 + M4). All pins routed to 0.1" headers.

A development board for the STM32MP1 Application Microprocessor with all MPU pins routed through to 2.54mm headers. No exotic proprietary connectors needed!

The power supply requirements for microprocessors are always complicated. I decided to use a discrete power supply scheme using a single LDO for the main 3.3V rail, a buck regulator for the DDR 1.35V rail and a load switch to detect the USB 1.8V rail. The latter comes from an internal regulator ands powers the VDD3V3USBFS and VDD3V3USBHS. This needs to be enabled only after the 1.8V rail comes up, so this needs to be enabled using a…
