Pushbuttons use two kinds of resistors: pull-up and pull-down. The one with 3.3V connected to the resistor is a pull-up resistor. It pulls the voltage upward. Meanwhile, pull-down resistors pull ...

In a short note, Adafruit also mentions that the board uses the A2 revision of the Raspberry Pi RP2350 SoC, which has an E9 erratum affecting GPIO pull-down resistors. This errata affects some uses of ...

The newly released RP2350 microcontroller has a confirmed new bug in the current A2 stepping, affecting GPIO pull-down behavior. Listed in the Raspberry Pi RP2350 datasheet (page 1340) as erratum R… ...

Documentation is limited with PDF schematics, “board shape”, 3D STEP file, blink code samples for the Arduino IDE and VS Code (C program), as well as a datasheet and user manual for the RA4M1. But it ...
