RPDot is an open-source project to create a tiny, hackable Raspberry Pi computer. It is based on the Raspberry Pi RP2040 microcontroller, which is a powerful and versatile chip that can be used to create a wide variety of projects.

The RPDot is designed to be as small and compact as possible, while still providing access to all of the features of the RP2040. It measures just 10x10mm, and uses only 0201 components to save space.

The RPDot features a castellated edge, which allows it to be soldered directly to a PCB. This makes it ideal for use in custom projects.

The RPDot also breaks out all of the important pins of the RP2040, including SWD, ADC, USB, and GPIO. This makes it easy to connect the RPDot to other devices and peripherals.

The RPDot is still under development, but it is a promising project that has the potential to create a new generation of tiny, hackable Raspberry Pi computers.
