WebJun 9, 2024 · Pinout The board routes one UART, I2C, and SPI bus to the pair of 0.1"-spaced headers on the board as well as six analog pins labeled A0-A5, eight GPIO configured as digital pins (with D38/IO38 to the Freebie pin). The headers also include the Reset and Enable pins as well as the voltage pins for VUSB, VBATT, and 3.3V. WebSep 5, 2024 · Setting the pin to input and disabling the pull-up/-down resistors seems the way to go. You would have to define a helper function that accepts low, high and float as parameters.

WebJul 12, 2024 · On the raspberry pi 3 all GPIO pins are powered up with a direction of "input". Each pin has a pull-up and a pull-down resistor associated with it. The status of these resistors is preserved through power loss or reset. (This is why there is no way to read the status of these resistors because they may not be known after a reset.) WebThe GPIO pin on the Pi is hooked up to Vg. It has a 10 Ohm current limiting resistor going into Vg and a 10k pull down resistor. Vs is grounded, and Vd has my device and 5 V source. The 5V source is what powers the Pi and is capable of producing 3 A. However, it doesn’t activate the MOSFET for some reason.
