Raspberry Pi’s lack, that uses variable voltages to connect to, for example, a potentiometers, joystick or light-
dependent resistor.

26 × multi-function 3.3V GPIO pins
2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels
8 × Programmable I/O (PIO) state machines for custom peripheral support.
Castellated module allows soldering directly to carrier boards.

The GPIO pins themselves feature castellation’s, small cut-out’s that permit the Raspberry Pi Pico to be soldered in
place into a project or carrier board.

More importantly, we can also solder header pins to the Pico and use it in a breadboard.

Retailing for under £4, the Raspberry Pi Pico is a cost effective means to tinker with electronics projects and study
physical computing.

You can use the power of Pico at the heart of robotics and motorized projects, collect data using sensors for tempera-
ture, humidity, light and pollution and you can learn the basics of programming and electronics.

The RP2040 may be the new kid on the block, but it has already brought lots of alternatives to the table, and this is
just the start for this low power, high speed chip.

First and third party accessories are the life blood of the Raspberry Pi and maker communities. They bring extra fea-
tures and enable projects to be realised more easily. With the Raspberry Pi Pico's new form factor there is a need for
new accessories and the first to market are Pimoroni, a UK based official Raspberry Pi reseller. They have released
12 new accessories for the Pico, nine of which are available at launch. They range from simple breakout boards ena-
bling multiple add-ons to be used at once, to advanced audio output devices and a VGA Demo board which uses the
Programmable IO of the RP2040 to create DVI video signals.
