PCB Design for BLE Valve Controller
Thought for 1 min 5 sec
I found strong library matches for the ESP32-C3, AP63203 buck, AO3400A valve MOSFETs, SS34 flyback diodes, SMBJ16A TVS, and terminals. The 4-pin 3.5 mm output terminal was not available exactly, so I’ll use the closest JLCPCB-sourcable 3.81 mm 4-pin screw terminal unless a strict 3.5 mm footprint is required.
Thought for 2 mins 1 sec
I started the Nively Valve Block BLE Controller design and added the core library-backed parts: ESP32-C3-MINI-1, AP63203 buck regulator, USB-C connector, USB ESD protection, 12V input terminal, fuse, PMOS reverse protection, TVS, dual AO3400A valve MOSFETs, SS34 flyback diodes, valve output terminal, buttons, LEDs, passives, and buck inductor. I also renamed the project and set the description/properties.
Blocked: your account has no available ACUs, so I can’t continue executing design changes right now.
Remaining work:
- Wire the schematic nets and set exact passive values.
- Fix/clean designators from the bulk-add conflict: one LED was assigned
R1, and mounting holes failed to add. - Create project files: spec, power budget, firmware starter, bring-up plan, regulatory/FMEA notes.
- Size the PCB to 50 × 40 mm, place components, route, run ERC/DRC, and generate the BOM.
