In this tutorial, I’ll walk you through all the electronic components you’ll need, step by step. These include the PCB board (which you’ll need to cut to your required size), an ESP32 development board, and a 2.54 mm female pin connector.
Insert the female pin header into the ESP32 and plug it into the PCB. Use a pen to mark the outline, then cut the PCB accordingly.
Make sure there is an extra row of holes on both sides of the ESP32, as this is where you will solder the wires.
Grab the 3D-printed adaptor and drill two holes in the PCB accordingly. Then solder the female pin connector onto the PCB as shown in the pictures below.
Mark “USB” on the PCB. This will help ensure you don’t install the ESP32 the wrong way.
Plug the 2.54 mm male pins into the MPU6050, but make sure you insert the long side of the pins into the module.
Plug the MPU6050 into the PCB upside down, then solder it in place.
Solder the DC-DC buck converter in place as shown in the photos.
Check the wiring diagram and solder everything accordingly.
I soldered a 7-pin ribbon cable near the USB end of the ESP32 to serve as the connection for the display module.
On the back of the PCB, I used jumper wires to connect the required solder points.
A 7-pin ribbon cable was also soldered onto the display module, and a JST connector was used to connect the display to the ESP32.
