- Set R32's Resistance to "10kΩ"
- Set R32's Role Details to "Battery monitor divider upper resistor from +12V_RAIL to BATTERY_ADC per requirement"
- Set R33's Resistance to "3.3kΩ"
- Set R33's Role Details to "Battery monitor divider lower resistor from BATTERY_ADC to GND per requirement"

Work done
- Completed the remaining schematic updates: replaced the RS-485 placeholder with U5 MAX485CSA+, powered it from 5V, wired UART/control nets, corrected DMX polarity labels to
DMX_PLUS/DMX_MINUS, and updated the battery monitor divider to R32=10kΩ / R33=3.3kΩ. - Verified OLED is on 3V3 with
I2C_SDA/I2C_SCL, dual XLR connectors are wired in parallel, and the user-input nets remain present for the 11 pots, 5 illuminated pushbuttons, and 4 toggles includingLOW_BATT_OVERRIDE. - Updated the project notes with the four-block organization and full GPIO/signal assignment table: Carousel Horse LED Controller Design Notes.
- ✅ User inputs implemented and documented.
- ✅ Comms/display updates completed, including MAX485, OLED, DMX XLRs, and monitor inputs.
- ✅ ALL_CAPS net labels used for the updated/significant nets.
- ✅ GPIO assignment table added to project notes.
- ✅ ERC check reports no ERROR or WARNING items.
- The schematic is complete; next I can proceed to PCB layout cleanup/placement for the newly replaced MAX485 and then routing/manufacturing checks.
