About the PhaseLatchMini PCB

PhaseLatchMini is an open source STM32 PCB design by AndersBNielsen, published on GitHub. It is a 4-layer board measuring 60.2 × 20.8 mm, with 63 components from 28 distinct parts.

Its main chip is the STM32F103C8TX, from the STM32 family. Other key parts include the MIC5504-3.3YM5. By type, the board carries 23 capacitors, 19 resistors, 8 connectors, 7 inductors, 2 ICs and 2 crystals.

It belongs with the rf & radio designs in this gallery.

From the project

High-rate continuous streaming of interleaved dual ADC (I/Q) samples over USB Full‑Speed (FS) using only the built‑in CDC class on an STM32F103C8 ("Blue Pill" style) board. Companion Python host tools provide live visualization, FIFO bridging, raw capture, diagnostics, and throughput benchmarking.

PhaseLatchMini: common questions

What microcontroller does the PhaseLatchMini use?

The PhaseLatchMini is built around the STM32F103C8TX, from the STM32 family.

How big is the PhaseLatchMini PCB?

The PhaseLatchMini measures 60.2 × 20.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the PhaseLatchMini?

63 components, from 28 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 PhaseLatchMini design files?

From the AndersBNielsen/PhaseLatchMini 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 PhaseLatchMini design in my own project?

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

Can I test firmware for the PhaseLatchMini 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.
