In my previous video I showed you the BLough Clock by Brian Lough. His design inspired me to also make a D1 mini board.
After designing the board, PCBWay offered me to order it using their services. In this video I will show you the board I made, how I used a soldering stencil and hot-air gun to solder SMD components on one side, and the soldering iron for the other side.
Then you can see me test the various components and finally I show you my first project made using this board: a remote controlled robot.

Board features:
- D1 mini complient headers
- Four through-hole prototyping areas
- 16 PWM output ports for LEDs, servos or motordrivers (using PCA9685)
- 16 digital I/O ports for sensors, LEDs or other devices (using PCF8575)
- 4-digit 7-segment LED display (using TM1637)
- 2x RGB LED
- 5-way joystick
- Buzzer, LDR and 2 extra buttons

Used parts for robot:
- Yellow geared motors and wheels (listed as "TT Motor Smart Car Robot Gear Motor")
- MX1616 dual motor driver module (listed as "Mini Victory L298N")
- 3D printed motor mount and filament wire connector rings
- 3D printed o-ring castor wheel
- 8-bit LED-indicator connected to PCF8575 to indicate direction. (See https://youtu.be/oG29a3th8ys )
- 5V USB-powerbank to power both motors and D1 mini
