[Stock issue] What if a part is out of stock when I place my order? Using JLCPCB’s pre-order.

In order to deal with out-of-stock issues like this one when they decide to order, JLCPCB allows pre-ordering, which means that the parts can be ordered before the PCB assembly is ordered and kept in stock at JLCPCB until the PCBA service is required. These pre-ordered parts are sent together with the PCB (and surface mount if you have also asked for surface mount), rather than separately from the PCB and only the parts are sent to you.

Create PCB by EasyEDA and order PCB by JLCPCB. If you want to keep costs down, request 2 boards to be mounted.

Create schematics in EasyEDA and convert the schematics to PCBs Work on the PCBs includes component placement, number printing, board outline drawing, wiring with auto routing, creating mounting holes and creating solid copper foil After completing the work on the PCBs, order the boards from JLCPCB.

[ESP32] From development board to designing your own printed circuit board and making it into a product

The cat-shaped talking robot Mia is developed on a home-made board using an ESP32 Wi-Fi Bluetooth module; this memorandum summarises the process from the initial development using an ESP32 development board to the creation of a home-made board and several changes for the product.

[JLCPCB] I received a confirmation email after ordering 100 boards. PCB operation is not checked

If there is no problem with the PCB layout, you will not receive an email from JLCPCB, so if you receive an email, it is when there is a problem, such as an incomplete circuit. Also, JLCPCB does not check the functionality of your own PCB, so you need to look at the schematic and PCB yourself to determine if the order is correct.
