Pilot is a prototyping breadboard power supply controller and interface expansion.
Main features
- 7-20V DC power supply
- High efficiency step-down power regulator module for 5V supply and 3.3V LDO
- Provides power to Raspberry Pi
- Switchable and protected 3.3V and 5V rails to breadboard
- Header (with jumper shunt) for current sensing
- Status LEDs (3x)
- Push buttons for power rails enable and user actions
- Can be used for MCU control (reset or flash programing)
- Pin header exposing Raspberry Pi UART, SPI, I2C and 4 GPIOs interfaces.
