Pseudonymous maker “iketsj” has turned a Raspberry Pi Pico right into a CircuitPython-compatible dev board echoing the traditional Arduino Uno pinout — utilizing a ProtoShield because the design’s circuit board.
“The elements that i’m going to make use of are a ProtoShield for Arduino boards as the bottom of the entire challenge, because it conveniently follows the Arduino 1.0 pin out. 7805 voltage regulator with accompanying elements to control exterior voltage enter down to five volts. Some diodes to order 5 volts and for reverse polarity safety. I haven’t got a pin-compatible energy jack so I am simply going to make use of a terminal block. Additionally a reset button.”
All put collectively, the ProtoShield turns into the house for a Raspberry Pi Pico – the primary board to hit the market that includes the dual-core Arm Cortex-M0+ Raspberry Pi RP2040 microcontroller. It is this which truly runs CircuitPython, the education-centric fork of the MicroPython challenge, and which handles the microcontroller duties — although, iketsj warns, “some GPIOs [General-Purpose Input/Output pins] are usually not linked to something — oh, properly!”
“In fact, it isn’t for vital stuff,” iketsj admits. “I simply wish to do an RP2040 in a, you could possibly say, traditional Arduino type issue. ‘Why not simply design a customized PCB relatively than simply doing it that method?’ True. Perhaps subsequent time.”
A video of the board’s meeting and check is now obtainable on iketsj’s YouTube channel.
