About the Ireng PCB

Ireng is an open source STM32 PCB design by ahsanu123, published on GitHub. It is a 2-layer board measuring 57.9 × 24.2 mm, with 66 components from 29 distinct parts.

Its main chip is the STM32F103RCTX, from the STM32 family. Other key parts include the USBLC6-2P6, SN74LVC2T45DCUR and AMS1117-3.3. By type, the board carries 24 resistors, 22 capacitors, 7 ICs, 5 connectors, 4 diodes and 2 transistors.

From the project

✒️ Ireng Probe - A custom Black Magic Probe with STM32F103RC.

Ireng is custom Black Magic Probe Based on STM32F103RCT. Only for fun 😙 and learning about debugging in microcontroller.

- ~~Add SPI Flash from windbond, jumat 17 januari 2025 at 19:51~~, no pin left for spi and dont want to change pinout of original schematic. - ~~re-check schematic, jumat 17 januari 2025 at 19:51~~ - add usb type c, and use usb micro b as backup, jumat 17 januari 2025 at 19:51

Ireng: common questions

What microcontroller does the Ireng use?

The Ireng is built around the STM32F103RCTX, from the STM32 family.

How big is the Ireng PCB?

The Ireng measures 57.9 × 24.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ireng?

66 components, from 29 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Ireng design files?

From the ahsanu123/ireng repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Ireng design in my own project?

The repository has no license, so all rights stay with ahsanu123. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Ireng 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.
