PowerWILL FAIL
Fine on a charger. Resets on a laptop.
Your motors want more current than the USB port can give. The board browns out the moment they move.
Fix: Add a separate 5 V supply for the servos.
Small beta now forming
Your board idea, built right the first time. No EE degree needed.
Tell Typmax what you want to build in plain English. It designs the circuit, checks it the way an experienced engineer would, and tells you what’s wrong in words you understand. You find the mistakes before you pay for boards.
- Describe it, don’t draw it
- Problems explained in plain English
- One-click fixes
FAILTwo servos on USB power. The 5 V budget sums to 2.5 A against the 500 mA a laptop port promises.
PASSI²C pull-ups 2.2 kΩ. Inside the 0.99–9.57 kΩ window for 400 kHz at 3.3 V.
PASSUSB-C CC resistors 5.1 kΩ. Inside 4.59–5.61 kΩ, so a charger sees a device.
FAILDisplay chip-select floats at boot. No pull-up on DS1.CS.

A desk robot: ESP32-S3, round display, and two servos.
A preview of the direction: bring the design, decisions, and feedback together in one workspace.
The problem
A board can look right and still be wrong.
One wrong resistor won’t show up on screen. It shows up weeks later, when the board arrives and won’t turn on. Then you fix it, order again, and wait again.
- 01You order boards and parts.The design looked finished.
- 02You wait one to three weeks.Your project sits still the whole time.
- 03It resets every time the servos move.Back to step one. A respin costs money and time, and it kills momentum.
Typmax finds those problems while they’re still free to fix.
How it works
Describe it in a sentence. Get a board you can build.
You decide what it should do. Typmax works out the voltages, resistor values and wiring rules.
-
Say what you want
What it does, how it’s powered, what it connects to. Write it the way you’d explain it to a friend.
“A desk robot with a round face display, a voice, and a head that turns.”“A single-cell LiPo charger”“A CAN bus node for my car” -
Typmax designs and checks it
It picks real parts, wires up the circuit, and reviews every connection. When something’s off, it tells you why.
-
Take it to a real board
The same design becomes a board you can send to a manufacturer. Nothing gets redrawn in another tool.
What it catches
Like having an engineer look over your shoulder.
You don’t get a list of error codes. Typmax tells you what will actually happen to your board, and how to fix it.
BootWILL FAIL
The screen stays blank at startup.
A pin is left floating while the chip boots, so the display can miss its wake-up signal.
Fix: One 10 kΩ resistor to 3.3 V. Typmax adds it.
StartupRISKY
It might not boot at all, some of the time.
Another part can hold a boot pin low during reset, so the chip starts in the wrong mode.
Fix: Move that signal to a safe pin.
ConnectionsWILL FAIL
The GPS will never get a fix.
The antenna input isn’t connected to anything. Easy to miss, impossible to fix after the board is made.
Fix: Route the antenna pin to the connector.
StandardsLOOKS GOOD
Your car network will accept it.
The cable termination matches what the standard expects, so it won’t disrupt other devices on the bus.
Fix: Nothing to do.
SafetyGET A 2ND LOOK
Batteries need a human sign-off.
All the safety checks pass, but anything that charges a lithium cell gets flagged for a second pair of eyes.
Fix: Have someone experienced confirm before ordering.
Who it’s for
You know what it should do. We’ll handle the electrical details.
Makers & hobbyists
Go past breadboards and modules to your own custom board, without spending a year learning circuit theory first.
- Turn a weekend project into a real PCB
- Learn why something is wrong, not only that it is
- Fewer dead boards in the drawer
Hardware startup founders
Get a working prototype in front of customers and investors before you can afford a full-time electrical engineer.
- Reach a working prototype sooner
- Spend less on respins
- Hand a clean design to your first hire or contractor
FAQ
Before you ask.
Common questions. Anything else, just email us.
Have a board in mind?Tell us what you’re building
We’ll tell you honestly whether it’s a good fit for the beta.
hello@typmax.com →Do I need to know electronics to use it?
You need to know what you want your device to do. Typmax handles the electrical decisions and explains each one, so you learn as you go. It’s built so that someone who has never designed a circuit can still end up with a board that works.
Why not just ask ChatGPT or Claude?
A chat answer gives you advice, not a design. Typmax keeps your board as a real, editable design and checks every connection against the actual parts you’re using, so what it tells you is grounded in your circuit.
Can I actually get a board made?
That’s the goal. The beta starts with designing and checking, and the path to manufacturing files is what we’re building with beta testers right now.
What if I already use KiCad?
Typmax writes standard KiCad files, so you can open the work in tools you already know. Importing existing designs isn’t in the first beta. If you need it, say so in the signup form.
Do I own my designs?
Yes. Your designs are yours. We’ll make data handling and export terms clear before access begins.
What will it cost?
The beta is invitation-only while we learn with a small group of builders. We’ll share pricing well before any wider launch.
More about the beta’s scope and privacy on the full FAQ.
EARLY ACCESS
