Botaniq V2
Thought for 12 sec
You can transfer the project to KiCad, but the best path depends on what you want to finish there:
Best option: export manufacturing/layout files
From Flux, export:
- Gerber ZIP — PCB copper, solder mask, silkscreen, drill, board outline
- BOM CSV — parts list
- Pick-and-place CSV — placement data
- Netlist if available — helps cross-check connectivity
Then in KiCad:
- Open KiCad → GerbView.
- Load the Gerber ZIP/drill files to inspect or manually recreate routing.
- Use the BOM and placement CSV as references.
- If you need editable KiCad PCB data, you’ll likely need to manually rebuild/import from these references, because Gerbers are manufacturing outputs, not fully editable design files.
Gerbers do not convert cleanly back into a KiCad schematic + editable PCB. They preserve the board artwork, but not design intent like components, nets, rules, or schematic symbols.
Better practical workflow
Use Flux to export:
- PDF schematic or schematic screenshots for reference
- BOM
- Gerbers
- Pick-and-place
- IPC/netlist if available
Then recreate the schematic in KiCad using the same parts and use the Flux routed board/Gerbers as a visual reference.
Before exporting
Your board still had unresolved routing cleanup issues last time:
- remaining airwires/unrouted connections
- copper overlap conflicts may need final verification
So I would not manufacture directly from the current Gerbers without checking them in a Gerber viewer first.
Export Flux files
Fix routing first

Board Bring-Up Plan — Botaniq Indoor v2 Mainboard
Prerequisites
- Current-limited 12 V bench supply, multimeter, oscilloscope if available, USB/serial programming setup for ESP32-S3 module.
- Start with no pumps or LED strip connected.
- Initial current limit: 250 mA for bare board power-up, then increase only after rails verify.
1. Visual Inspection
- Confirm orientation of D1 AO3401A, TVS1 SMBJ18A, D2-D8 SS14, U2/U3 MP1584EN, Q1-Q7 AO3400A, and all polarized connectors.
- Check solder bridges around ESP32-S3 header/socket, MP1584 pins, and WS2812B LEDs.
- Confirm input barrel jack is center-positive.
2. Power Rail Verification
Table
| Rail | Source | Expected | Measure at | Current limit / pass criteria |
|---|---|---|---|---|
| 12V_IN_RAW | J1 center through F1 input | 12 V | J1 center / F1 pin 1 | Bench supply reads <250 mA before buck startup load |
| 12V_PROT | F1 + D1 reverse-polarity stage | ~12 V | TVS1 cathode, pump connector P1 | Within diode/FET drop of input |
| 5V | U2 MP1584 buck | 5.0 V | C2 P1 / 5V net | 4.75–5.25 V, ripple preferably <100 mVpp |
| 3V3 | U3 MP1584 buck | 3.3 V | C5 P1 / U1 3V3 | 3.20–3.40 V, ripple preferably <75 mVpp |
| GND | Common return | 0 V | J1 terminal, ESP32 GND pins | Continuity across all ground points |
Procedure:
- With power off, measure resistance from 12V_PROT, 5V, and 3V3 to GND; investigate any near-short.
- Apply 12 V with 250 mA current limit and verify 12V_PROT.
- Verify 5V, then 3V3 before plugging in pumps or LED strip.
- If any regulator output is wrong, power off and inspect MP1584 feedback, inductor, BST, COMP, and FREQ components.
3. Critical Signals
Table
| Signal | Expected idle state | Test |
|---|---|---|
| ESP_EN | High at 3.3 V | RESET button pulls low, releases high |
| ESP_BOOT_IO0 | High at 3.3 V | BOOT button pulls low for flashing |
| PUMP1_GPIO..PUMP6_GPIO | Low at boot | Pumps off at reset |
| LED_STRIP_PWM | Low at boot | LED strip off at reset |
| I2C_SDA / I2C_SCL | High at 3.3 V | I2C scan should find OLED 0x3C and BH1750 0x23/0x5C when connected |
| WS2812_DATA_GPIO | 3.3 V logic waveform when firmware updates LEDs | Check LED1 DIN if LEDs do not light |
4. Connector and Functional Tests
Table
| Connector / block | Test |
|---|---|
| J-P1..J-P6 pump outputs | Connect one pump at a time; command one channel; verify only that pump runs |
| J-LED | Attach 12 V LED strip after rail checks; verify PWM dimming and MOSFET temperature |
| JS1..JS6 sensors | Verify pinout: Pin 1 = 3V3, Pin 2 = GND, Pin 3 = filtered ADC signal |
| J-OLED | Verify 3V3/GND/SDA/SCL and OLED address 0x3C |
| J-LUX | Verify 3V3/GND/SDA/SCL and BH1750 address 0x23 or 0x5C |
| LED1-LED6 | Firmware should show dim green idle status |
| SW1 | Serial monitor should report button pressed when SW1 is held |
5. Programming
- Use the firmware starter project file for PlatformIO setup.
- To enter bootloader: hold BOOT, tap RESET, release BOOT, then upload.
- Confirm serial output at 115200 baud after reset.
6. Design Notes / Production Checks
- MP1584 COMP/FREQ support values are present as schematic placeholders and should be final-verified against the exact MP1584EN datasheet before production build.
- The input fuse is a 5 A / 125 V SMD fuse placeholder because the requested 3 A PPTC was unavailable in the library.
- Test with actual pump and LED-strip current loads while monitoring U2, U3, Q1-Q7, D1, and F1 temperature.
