The Raspberry Pi Foundation continues to add new devices to its product range. And if a few weeks ago he surprised us with this keyboard with Raspberry inside that responds to the name of Raspberry Pi 400 a few hours ago he repeated the play by presenting his «Raspberry Pi Pico« a microcontroller based on its RP2040 chipset and that can already be yours for only 4 euros.
In this sense, the new Raspberry is closer to what Arduino proposes, than to classic products such as Raspberry Pi or Raspberry Pi Zero. In fact, as the foundation explains in the notes accompanying this release, Arduino is one of the companies that has partnered with Raspberry to develop accessories compatible with the Pico, plus it will use the RP2040 boards for its next Arduino Nano RP2040 Connect.
Comment James adams COO of the organization to explain why they have decided to enter this field, that “while the Raspberry Pi takes care of the heavy computing, network access and storage, the new microcontroller takes care of the analog input and I / O It’s low latency and sometimes provides a very low power standby mode. ‘
The specifications are therefore not comparable to those of the other products they offer. We speak in this sense of a tiny plate built around a design Arm Cortex-M0 + Dual-core operating at 133 MHz, 26 kilobytes of on-chip RAM, and support for up to 16 MB of off-chip Flash memory via a dedicated QSPI bus.
The new microcontroller also has its own power supply, which supports voltages between 1.8 and 5.5 watts, so two or three AA batteries or a small rechargeable battery are enough to start it up.
Along with the new device, the foundation has released a SDK based on C, accessible from any of the main development environments, such as Visual Studio Code; plus another based on Python 3.
In addition to Arduino, at the time of its launch, companies such as Adafruit, Pimonori and Sparkfun have developed their own accessories for the “Pico”.
