Today, Raspberry Pi has announced the launch of their new board – and what a surprise it is! It is their first micro-controller and is called the Raspberry Pi Pico!
Raspberry Pi Pico has been built around Raspberry Pi’s own silicon, developed in-house by them over the last few years. The chip, the RP2040, is a dual-core ARM Cortex M0+ processor, with a flexible clock running up to 133MHz.
- RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom
- Dual-core ARM Cortex M0+ processor, flexible clock running up to 133 MHz
- 264kB of SRAM, and 2MB of on-board Flash memory
- Castellated module allows soldering direct to carrier boards
- USB 1.1 Host and Device support
- Low-power sleep and dormant modes
- Drag & drop programming using mass storage over USB
- 26 multi-function GPIO pins
- 2×SPI, 2×I2C, 2×UART, 3×12-bit ADC, 16×controllable PWM channels
- Real-time clock (RTC)
- Temperature sensor
- Accelerated floating point libraries on-chip
- 8×Programmable IO (PIO) state machines for custom peripheral support
It runs both C/C++ and MicroPython and you can see a pinout of this very capable little board below:
One of the most impressive things about the Pico is the price – just $4/£3.60 or thereabouts.
You can buy the Pico from The Pi Hut, and of course from the pirates at Pimoroni and other official resellers. Pimoroni, in particular, have gone all-out to release a set of extras – check them out here.
Pimoroni have also been working on the tinyest 2040-based board called the Tiny 2040 – it’s coming soon and is the size of the end of your finger!
If you subscribe to Hackspace magazine, or you’re lucky enough to find a copy in a newsagent/supermarket, there is a FREE one on the cover this month!
Thinking to yourself “oh, it’s just a microcontroller”? Take a look at Dave Akerman’s post in which he uses the Pico as a high altitude balloon tracker! Take a look also at Russell’s experiments with Pimoroni breakout garden displays!
Take a look also at Jeff Geerling’s blog for his review. He highlights one of the flaws with the Pico – a lack of pin labelling on the top of the board which means that once it’s plugged into a breadboard, or even a carrier board, you have to consult a pin-out to find out which pin’s which. You can check out his review video below:
