From the project
The electronics stack consists of two PCB.
The electronics stack consists of two PCB.
The first main PCB is the main EPS PCB. It contains most of the components including DCDC for 5V, 6V, 3V3, connection to Raspberry Zero 2W, power switch and power indication LED, as well as onboard power monitoring for all three voltage bus via the INA3221, onboard MPU6050 with external connection option, as well as connector to the PWM Driver PCB.
