Description
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.

Firmware
Serial communication
Available commands:
| Type | Length [bytes] | Value | Description |
|---|---|---|---|
| 0x02 | 1 | command id | Ack |
| 0x10 | 4 | phase shifts (0 - 15) | Set phase |
| 0x11 | 0 | - | Transmit |
| 0x12 | 1 | latch state | Latch state |
After each message microcontroller should send ACK message with payload containing command id of original message
Example routine to set new phase delay:
0x12 0x01 0x00- make sure that latch is set low in order to accept data via serial interface0x10 0x04 0x04 0x02 0x0f 0x08- send phase shifts to the controller0x11 0x00- transmit phase shifts via SPI to the phase shifters0x12 0x01 0x01- set latch to update phase shift0x12 0x01 0x00- reset latch
Buttons and LEDs
The board is equiped in 3 tactile buttons and two 4-led displays where each display shows according to the silkscreen description either currently selected phase shifter or phase shift set for the selected phase shifter. Buttons have following functions starting from the left most button:
- On short press transmits current phase shifter configuration over SPI
- On short press cycles through 4 phase shifters, on long press sets all phase shifters to 0
- On short press increments phase delay, on long press set current phase shifter to 0

Questions
How big is the Controller PCB?
It measures 54 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
67 parts, built around the TPS60403DBV, USBLC6-2SC6 and SMAJ5.0A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Controller KiCad files?
From the kamilix2003/Phase-Shifter repository on GitHub, at the commit this page was made from: the board is KiCAD/Controller/Controller.kicad_pcb and its schematic KiCAD/Antenna_array/Antenna_array.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
