My STM32 Bluepill projects

Post by profdc9 »

Since this is a new stm32duino, I thought I would talk about the projects I've developed, so far with Roger's core


A theremin that has both pitch and volume control and digitally synthesizes the audio signal using an external DAC (MCP4921).

Vector Network Analyzer (VNA) from 100 kHz to 600 MHz:

This is a 2-port VNA that is good for testing antennas, filters, or other components. It really is an impedance meter, but provides results that are consistent with 50 ohm ports.

Modular Antenna Tuner for HF band (1.8 MHz-30 MHz):

A homebrewed antenna tuner for the HF band that automatically matches the impedance of an antenna to 50 ohms. It has ICOM rig support as well.


A Bluepill you can build or modify yourself that uses generic parts (except for the STM32F103C8T6).


A Bluepill pinout compatible board that uses the STM32F405RGT6 processor.
