PiSquare enables wireless Raspberry Pi HAT control though ESP8266 and RP2040 MCUs (Crowdfunding)

PiSquare Wireless Raspberry Pi HAT RP2040 & ESP8266

SB Components PiSquare is a board following the Raspberry Pi HAT form factor, and based on Raspberry Pi RP2040 microcontroller & ESP-12E Wireless module in order to control multiple Raspberry Pi HATs wirelessly without stacking them on their Raspberry Pi. The PiSquare uses Socket programming to control multiple Raspberry Pi HATs wirelessly, and for instance, you could connect multiple HATs with SPI or UART without the expansion boards conflicting with each other since the physical interface is handled by the Raspberry Pi RP2040 on each PiSquare connected over WiFi (ESP8266) to the Raspberry Pi SBC. PiSquare hardware specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz Storage – 16Mbit SPI flash Display – 0.91-inch OLED display Connectivity – 802.11b/g/n WiFi 4 via ESP-12 (ESP8266) module USB – 1x USB Type-C port 40-pin header and form factor compatible with the official Raspberry Pi HATs Power Supply […]

How to Install dnsmasq caching DNS server in Ubuntu

As you may have noticed in recent days, my domain registrar (HostFast) suspended cnx-software.com domain for what I believe are dubious reasons, meaning the site was inaccessible to the outside world and myself. I cannot do much about the latter and I’m held hostage to what the domain registrar’s will, but I was able to access my own website with my domain name after installing a DNS server through dnsmasq on my Ubuntu 20.04 laptop. Edit: most of the steps below are actually not needed in Ubuntu 20.04, since you could just edit /etc/hosts (step 4). I’ll just leave the instructions below in case somebody needs to install dnsmasq. Here are the steps I followed. Install dnsmasq

sudo apt install dnsmasq

1	sudo apt install dnsmasq

This did not work at first since systemd-resolved is already installed, so I disabled it by following instructions on askubuntu:

sudo systemctl stop systemd-resolved
sudo systemctl disable systemd-resolved
sudo systemctl mask systemd-resolved

sudo systemctl stop systemd-resolved

sudo systemctl disable systemd-resolved

sudo systemctl mask systemd-resolved

I then added name servers to /etc/dnsmasq.conf:

server=8.8.8.8
server=4.4.4.4

1 2	server=8.8.8.8 server=4.4.4.4

and cnx-software.com IP […]

Bluetooth LE audio evaluation kit supports nRF52840 Bluetooth Low Energy SoC

Software company Packetcraft has announced the availability of its Bluetooth LE audio evaluation kit for the Nordic Semiconductor nRF52840 Bluetooth Low Energy SoC used to let engineers evaluate the technology and develop Bluetooth LE Audio applications. Bluetooth LE audio was first announced in January 2020 together with the LC3 audio codec, and promised to deliver a much longer battery life for your Bluetooth headphone or battery-operated speaker, as well as support for multi-stream and broadcast audio. But it’s taken some time before being adopted in chips like Qualcomm QCC305x/QCC3056 or FastConnect 7800, as well as operating systems with, for instance, Android 12 being the first version of Android with LE audio support. The kit is comprised of three Nordic Semi nRF52840-DK boards each fitted with a Packetcraft audio interface board (AIB) equipped with two 3.5mm audio jacks for microphone and speaker, plus a ground loop isolator, three 3.5mm audio cables […]
