Ada is an autonomous hardware engineer: it draws the schematic, proves it with KiCad's own checks, and routes a board you can send to the fab.
It finds the floating ground and the missing pull-up while the design is still a file, not after the boards show up.
6 of 6 test boards come out with zero ERC errors, zero DRC violations, and a schematic that matches the board. USB routes as a coupled pair at a fixed 0.25 mm gap.
What Ada designs, how it checks it, and what it hands you.
Every claim about the board names the check that proved it. One failed check stops the run.
Ada drives the KiCad you already have. Every stage opens in the editor, and nothing that costs money runs until you approve it.
KiCad's ERC runs while Ada draws. A floating ground pin in round one is fixed by round two.
propose · round 1 ✗ AMS1117-3.3.GND is on no net put it on the ground net ✗ erc.pin_not_connected U1 pin 1 propose · round 2 ✓ one ground: GND ✓ erc clean
Ground poured on both layers and stitched together. USB routed as a real differential pair.
Ada reviews its own design like a skeptical senior engineer. Every finding names the pins and the fix, and anything the netlist can't back gets dropped.
HIGH Serial header TX and RX wired straight through
TXD0 lands on the header pin named TXD. On an FTDI adapter that pin is an output too, so two drivers fight and both receivers float.
fix: cross the pair, TXD0 to header RXD
HIGH No pull-ups on SDA and SCL
The Qwiic port hangs off IO21 and IO22 with nothing pulling either line to 3.3 V. I2C is open-drain, so the bus never idles high.
fix: 4.7 kΩ from SDA and SCL to +3V3
HIGH The header's 3.3 V pin backfeeds the regulator
The header shares the regulator's output net with no diode, so a 3.3 V cable and USB-C plugged in together fight each other.
fix: a Schottky or a solder jumper on that pin
