Sprocket designing a robot controller schematic and previewing it as an artifact while other threads run in parallel

Designs electronics

Describe a device, and Sprocket designs the circuit around real parts.

Draws clear schematics from the datasheets of the parts it picks
Writes the BOM, pin maps, and step-by-step assembly guides
Writes and tests the firmware that runs on the board

Design the electronics for a 4-motor robot car I can drive over Wi-Fi.

Read ESP32-CAM, TB6612FNG, and LM2596 datasheets

Wrote docs/assembly.md with 12 steps

Works from real docs

Sprocket checks current sources before it acts, so its answers hold up on real hardware.

Searches the web and reads full pages, not just snippets
Reads PDFs, spreadsheets, and images you share
Runs commands to confirm the fix works

My BNO085 IMU only reads zeros on the Raspberry Pi. Why?

Searched the web for "BNO085 Raspberry Pi I2C"

Read learn.adafruit.com · BNO085 Python setup

Read BNO08x-datasheet.pdf · I2C interface

sudo nano /boot/firmware/config.txt

The Pi's I2C controller doesn't handle the BNO085's clock stretching well. I set the bus speed from Adafruit's guide, and the IMU now reports orientation.

Verified 100 Hz readings for 60 seconds

Buys what the project needs

Sprocket orders parts and subscriptions for you, within limits you set.

You approve each spending limit once with a passkey
Limits are locked to a merchant and an amount
Unused money goes back as soon as the order completes

Asks before guessing

When a request is ambiguous, Sprocket asks a quick question instead of assuming.

Multiple-choice answers for design choices, frameworks, and parts
An option to let Sprocket decide when you don't mind
Your answer goes straight into the work

Splits big tasks

Sprocket hands parts of a large task to subagents and keeps working while they run.

Subagents run in the background and report back when they finish
Each subagent has its own context, so the main thread stays focused
Subagents can work in their own git worktrees

Edited firmware/motors.cpp

A copy-paste bug capped M2 at 90% duty. I fixed it, and all 18 motor tests pass.
