Robot controller board for Raspberry Pi (Zero W)

• 4 motors
• 4 servos
• Battery voltage divider/monitor
• 6-DOF IMU (MPU6050)
• Pi <-> Arduino Communication via I2C, SPI, and UART (Serial)

Components used:

• 2x MX1508 Motor Driver IC
• 2x 4.7K SMT Resistors (Arduino I2C pull-ups)
• 1x 2.2K SMT Resistor (Voltage divider high side)
• 1x 1K SMT Resistor (Voltage divider low side)
• 1x 10K SMT Resistor (Arduino reset pull-up)
• 1x Atmega328pb (B variant has 2x I2C needed for MPU6050)
• 1x 2x20 Stacking header (You can use male or female for your project)
• 1x 2x3 SMT Header for ICSP connection (Optional)
• 1x DROK Mini DC-DC voltage converter (Make sure to set to 5V)
• 1x 1x4 Male header pins for voltage regulator (1x3 works, EN is not connected)
• 4x JST Headers for motor connections (Can use standard headers too, 2.54mm pitch)
• 4x 1x3 Male header pins (2.54mm pitch) for servos (Or 3x 1x4)

I’ll be adding code to run this at my github, http://bit.ly/RoboHAT
I ordered almost everything from AliExpress, but some of the SMT parts I had laying around
