I’m blocked again because the account has no available ACUs, so I can’t continue executing schematic edits right now.
Accomplished in this session:
Added the core real components: ESP32-S3-WROOM-1-N16R8, TPSM63610 5 V buck, LMR33630 3.3 V buck, TPS7A2033 audio LDO, TPS259474 eFuse, DRV8874, 74LVC2G08, USB-C, ESD, fuses, connectors, MOSFETs, test points, LEDs, ferrite bead, and support passives.
Wired major power architecture: 12 V battery input, input fuse/reverse MOSFET/TVS/bulk, BAT_PROTECTED distribution, MD10A/TB6600/myRIO branches, TPSM63610 +5V_MAIN, fused +5V_LOGIC/+5V_SERVOS/+5V_MARKER, +3V3_DIGITAL, +3V3_AUDIO, ESP32 power/EN/BOOT, and USB-C native USB D+/D− with CC pull-downs and VBUS sense.
Used datasheet-backed values for the TPSM63610, LMR33630, TPS7A2033, ESP32-S3 boot/reset, and USB-C sink behavior.
Open items:
The schematic is not complete yet: microphones, servos, TB6600 MOSFET sinks, myRIO UART, DRV8874/AND-gate marker motor logic, LEDs, and several test points still need final wiring.
The TPS259474 myRIO eFuse configuration pins need proper individual resistor/cap networks; I had flagged the current placeholder approach for correction.
Schematic organization/placement and ERC cleanup have not been completed.
Final fuse values, battery max voltage, motor/servo stall currents, TB6600 resistor values, and myRIO input limits are still TBD.
Suggested next steps once ACUs are available:
Finish wiring the remaining signal/interface blocks.
Correct the myRIO eFuse configuration network.
Organize the schematic into readable functional blocks.
Run ERC/design review and fix real violations before moving to PCB layout.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
