// embedded systems education

Firmware skills, taught by someone who ships them.

Hands-on embedded systems training from a working firmware engineer — C/C++, RTOS, and the communication protocols that actually run on production hardware.

What you can learn here

One course is live today. The rest are being built in the open — you'll see them here as "in development" rather than nowhere at all.

// why sofirm

A small program, on purpose

Built by a working engineer

Courses are written and maintained by someone shipping embedded firmware day to day, not a curriculum team.

Real hardware, real protocols

UART, SPI, I2C, AT commands — the same interfaces used on production boards, not just simulators.

Direct feedback, not a crowd

Small cohorts mean questions get answered by a person who read your code, not a forum queue.

Why this exists

SoFirm is built and taught by Thabiso Nxumalo, an embedded firmware engineer working hands-on with microcontrollers, RTOS, and telemetry hardware — STM32-based firmware, GSM/GPS systems, UART/SPI/I2C interfaces, and the PCB and schematic design that ties it all together.

Most embedded courses are taught by people who left the field years ago. This one is written between actual debugging sessions — so what you learn is what's currently being used to ship real hardware, not a syllabus frozen in time.
