About the Controller PCB

Controller is an open source STM32 PCB design by kamilix2003, published on GitHub under the MIT license. It is a 2-layer board measuring 54 × 35 mm, with 60 components from 16 distinct parts.

Its main chip is the STM32G0B1CBTX, from the STM32 family. Other key parts include the AP2127K-3.3, TPS60403DBV and USBLC6-2SC6. By type, the board carries 18 resistors, 16 capacitors, 12 diodes, 6 connectors, 4 ICs and 3 switches.

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

From the project

Interface for RF phase shifter as part of phased antenna array

STM32G0B01 based board for controlling daisy-chained digital phase shifter via SPI-like serial interface. User can interface with the board either by buttons and LEDs on the board or via virtual serial port over USB, communication over serial port is realized using simple TLV protocol. The board is providing bipolar supply for the phase shifters.

Available commands: | Type | Length [bytes] | Value | Description | |----------|--------------------|-----------------------|-------------| | 0x02 | 1 | command id | Ack | | 0x10 | 4 | phase shifts (0 - 15) | Set phase | | 0x11 | 0 | - | Transmit |…

Controller: common questions

What microcontroller does the Controller use?

The Controller is built around the STM32G0B1CBTX, from the STM32 family.

How big is the Controller PCB?

The Controller measures 54 × 35 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Controller?

60 components, from 16 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 Controller design files?

From the kamilix2003/Phase-Shifter 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 Controller design in my own project?

Yes, under the terms of its MIT license, which kamilix2003 chose for the repository.

Can I test firmware for the Controller 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.
