About the LogPeaker PCB

LogPeaker is an open source STM32 PCB design by plen-maker, published on GitHub. It is a board, with 4 components from 4 distinct parts.

Its main chip is the STM32MP257F, from the STM32 family. By type, the board carries 1 IC, 1 transistor, 1 connector and 1 resistor.

From the project

An open, extensible board-diagnostics cockpit. Connect to a board over a transport (serial, CAN, or raw USB), let a decoder plugin turn the raw stream into named signals, and benchpeek does the rest: live table, live plot, session record/replay, and a rule engine that turns value

An open, extensible board-diagnostics cockpit. Connect to a board over a transport (serial, CAN, or raw USB), let a decoder plugin turn the raw stream into named signals, and benchpeek does the rest: live table, live plot, session record/replay, and a rule engine that turns values into a plain-language diagnosis ("VBAT 10.2 V — battery voltage out of range, check charging system").

LogPeaker: common questions

What microcontroller does the LogPeaker use?

The LogPeaker is built around the STM32MP257F, from the STM32 family.

How many components are on the LogPeaker?

4 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the LogPeaker design files?

From the plen-maker/LogPeaker repository on GitHub, which has a netlist; the links under Design files point to each one.

Can I use the LogPeaker design in my own project?

The repository has no license, so all rights stay with plen-maker. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LogPeaker 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.
