README
hardware/controller-f407/README.mdF407 controller schematic
This is the new controller, started from the outside in. The rotor interface and the AC motor drive are on rotor_drive. The Drive MCU and the analog front end are the next two sheets.
The directory is hardware/controller-f407/ because ADR 0014 names the STM32F407, and the tree sits beside the imported V4 project at hardware/controller/ without mixing files. Leave hardware/controller/ untouched. It is the reference for the V4 TVS, snubber, and connector practice.
| File | What it is |
|---|---|
controller-f407.kicad_sch | Root sheet. rotor_drive, drive_mcu, and analog_input hang off it. +5V and AC_FUSED stay no-connects until the power sheet exists. |
rotor_drive.kicad_sch | Azimuth rotor connector, motor caps, triac drive, ARM relay, 26 VAC tap. |
drive_mcu.kicad_sch | Drive MCU, STM32G431RBT6. Power, SWD, and the UART to the Station. |
analog_input.kicad_sch | Pot front end, the VIN_RECT warning, and the ADC reference filter. |
rotor-drive.pdf | Plot of both sheets, for review away from KiCad. |
DESIGN-NOTES.md | What each block does, the calculations, the bill of materials, and the open questions. |
symbols/controller-f407.kicad_sym | Unused TPS3823-33 symbol (the supervisor is not on the rotor sheet) and the no-pad Powerpole gland marker. |
footprints/controller-f407.pretty/ | The two motor-cap footprints copied from the Hammond outline, and the gland marker. |
KiCad 9. Nets leave rotor_drive on hierarchical labels (AZ_CW_EN, AZ_CCW_EN, AZ_BRAKE_EN, ARM_EN, ZC_SENSE, and the rest listed in the design notes). The pin assignment is in the Drive note. Through-hole parts are bought from Mouser. SMT parts that have a checked LCSC number say so on the symbol; the rest are TBD.
Elevation is a later copy of this sheet (ADR 0008), not a second channel here.

Questions
How big is the Controller f407 PCB?
It measures 159 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller f407 use?
122 parts, built around the BTA16-600SWRG, LTV-814S-TA1, MOC3023SM and BAT54. 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 f407 KiCad files?
From the wa1hco/rotator_controller repository on GitHub, at the commit this page was made from: the board is hardware/controller-f407/controller-f407.kicad_pcb and its schematic hardware/controller-f407/analog_input.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller f407 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
