A circuit that runs in the simulator still has to be bought and wired on a desk. The build guide turns your Mokxi project into one printable page for that: the shopping list, the schematic, the wiring step by step, a pin table, the code, and the checks to do before you plug in USB. Beside it, Order these parts sends the same list to a store. The demo above is the built-in Keypad lock: an Uno, a 4x4 keypad, an RGB LED, a relay and a lamp. Its guide is a good example of why a list helps, because a project like this needs a dozen parts and over twenty wires, and missing one means a second order. ## Open the build guide Open Export in the editor’s header, next to Share, and press Build guide (PDF). The guide opens in a panel over the editor. Print or save as PDF sends it to your browser’s print dialog, where Save as PDF makes the file, and Shopping list (CSV) downloads the parts as a spreadsheet. Everything is read from the project as it stands: the parts on the canvas, the nets as the wire labels see them (breadboard strips and plugged-in pins included), a picture of the circuit and the project’s own code files. Change the circuit and open the guide again; it is drawn fresh each time. ## What is in it The shopping list comes first, one row per part with its quantity, value and color, an estimated price each and in total, and a search link. The prices are estimates in US dollars for budgeting, not a quote: the store sets the real price. Jumper wires are one line. Then the schematic as a full page, and the wiring as numbered steps grouped into ground, power and signals, so you wire the grounds first, the way a careful bench build goes. A pin table lists every board pin in use and what it connects to. The code follows, every file of every board in the project. Last is a power-on checklist written for that project: unplug while you wire, check every ground is shared, count the wires against the steps. It adds lines for what the circuit has, such as which leg of an LED goes to the pin, checking resistor bands against the list, and giving motors, servos and relays their own supply when they need it. ## The shopping list as a spreadsheet Shopping list (CSV) has the columns Quantity, Part, Type, Value, Color, Category, Est. each (USD), Est. total (USD) and Search, and a last row with the estimated total. Open it in any spreadsheet to tick off what you already own, or hand it to whoever is buying for a class. This is different from the PCB view’s bill of materials, which lists footprints and designators for a fabricated, assembled board. The shopping list is for loose parts on a breadboard. ## Order these parts Order these parts is in the Export menu and at the foot of the build guide. Pick a store and the list becomes what that store takes. Your country picks the first store, and the editor remembers the one you choose. On Amazon.com, Amazon.in and Amazon.com.br it is one link that adds every matched item to your cart. AliExpress has no multi-item cart link, so you get a link per item. LCSC, DigiKey and Mouser get a BOM file to download and a button that opens the store’s own BOM tool, where you upload it. A part with no matched product at that store is listed with a search link there, never a guess. Where a link carries a partner tag, the panel says before you press it that Mokxi may earn a commission at no extra cost to you. Without one, it says the links go straight to the store. Prices, stock and shipping are always the store’s. ## Common problems The Build guide button is dim: the canvas is empty. The exports need at least one part to work from. A part shows no price or no product: not every part has an estimate or a mapped product at every store. Use the search link on its row, or try another store. The guide opens blurred: on Free it is a preview of your own project’s guide, with the cover, the totals and the first rows and steps readable and the rest blurred behind Get the full guide with Pro. Order these parts is missing on a school account: for a student in a class or a child account it is off unless the teacher turned it on for the class. ## Questions Is the build guide free? The full guide, its print or PDF and the shopping list CSV come with Pro; a 14-day trial that needs no card unlocks them too. On Free the guide opens as a preview of your own project. Students in a class keep the exports on any plan. Is Order these parts a Pro feature? No. It works on every plan, Free included, even from the guide’s preview. For a student in a class or a child it is off unless a teacher turns it on. Are the prices exact? No. They are estimates in US dollars for budgeting a build. The store you order from sets the real price, and pack sizes differ. Which stores can I order from? Amazon in the US, India and Brazil as one cart link, AliExpress as a link per item, and LCSC, DigiKey and Mouser as a BOM file for their BOM tools. Can I print the guide for a class? Yes. Print or save as PDF uses your browser’s print dialog, and the page is laid out for paper, so each student or group can have the parts, the steps and the code in hand.
