Raspberry Pi Development

Raspberry Pi has added a wireless module to its Pico microcontroller board, giving it 802.11n Wi-Fi capability – all for $6. Pico W, as it will be known, is just the same size as the original Pico (~ 21 x 51mm) – which was recently qualified for operation across -40 to +85°C for industrial users – and has the same pin-out. ...

At Embedded World  today, Raspberry Pi was giving away its Pico development boards to all comers, to emphasise that there is no shortage of its RP2040 microcontroller, which was recently qualified for the industrial -40 to +85°C temperature range – previously it was to -20°C. “We risk-bought quite a lot of wafers, and could sell one to two million per ...

I have just put a fan case around my Raspberry Pi 4 – on which I am typing these very words. The brushless fan, from Pi Hut, is always on and, while it is commendably quiet, could be even quieter – especially as Raspberry Pi OS now includes an on-off control option that depends on CPU temperature. See part 2 ...

Having found it so easy to put 64bit Raspberry Pi OS onto an SSD drive, and then discovering that Raspberry Pi 4 is more nippy running from an SSD card (as everyone said it would be), the next step was to get a case could support both the drive and the Pi so that the cable is not constantly being ...

I cannot believe how simple it is now to get a Raspberry Pi 4 running from an SSD rather than from an SD Card. I have written what to do here, because the web seems devoid of a simple list of instructions just at the moment. It is a newly-smoothed process – in the last month or so – and ...

Sfera Labs of Milan has launched an 80 x 80mm multi-sensor edge-computer built around the Raspberry Pi RP2040 microcontroller. Called Exo Sense RP, module integrates temperature, humidity, VOC (air quality – volatile organic compounds), light and motion sensors, as well as a microphone with audio processing. RP2040 has two Arm Cortex-M0+ cores, 16Mbyts of flash and 264kbyte of ram. Clocking is ...

The winners of the 2022 Raspberry Pi coding competition organised by PA Consulting have been announced, with schools across the UK having been challenged to solve problems using the the single-board computer. Now in its tenth year, “Saving the planet” via sustainability was the challenge, to be addressed by school children in different age groups. And the entries covered a ...

In celebration of Pi Day, element14.com has launched the Raspberry Pi Pi-Fest Design Challenge. This design challenge will put Raspberry Pi Pico at the centre stage as community members will use the device, coupled with any other Raspberry Pi products of their choice, to create music or audio-themed project. Fifty sponsored challengers will receive a Raspberry Pi Pico kit free of charge ...

Maker Mahesh Venkitachalam has designed a high quality microphone he calls Mico using the main component of the Raspberry Pi Pico  – the RP2040 controller chip – which can be bought separately from the Pico platform. The sensing device is a MEMS microphone that outputs a pulse density modulated (PDM) signal. Mahesh designed a PCB that holds the RP2040 with ...

Digi-Key Electronics has partnered with Make – the publishers behind the maker magazines and books – to release an augmented reality (AR) app to accompany its 2021 Boards Guide. Divided into sections for microcontroller (MCU), single-board controller (SBC) and field programmable gate array (FPGA)-based boards, the guide helps students, makers and professional engineers navigate the latest technology for their possible ...
